There’s nothing like a glass of cool, clear water to quench one’s thirst. But the next time you or your child reaches for one, you might want to question whether that water is in fact, too toxic to drink. If your water is fluoridated, the answer may well be yes.

For decades, we have been told a lie, a lie that has led to the deaths of hundreds of thousands of Americans and the weakening of the immune systems of tens of millions more. This lie is called fluoridation. A process we were led to believe was a safe and effective method of protecting teeth from decay is in fact a fraud. In recent years it’s been shown that fluoridation is neither essential for good health nor protective of teeth. What it does is poison the body. We should all at this point be asking how and why public health policy and the American media continue to live with and perpetuate this scientific sham.

How to Market a Toxic Waste

We would not purposely add arsenic to the water supply. And we would not purposely add lead. But we do add fluoride. The fact is that fluoride is more toxic than lead and just slightly less toxic than arsenic.”(1)

These words of Dr. John Yiamouyiannis may come as a shock to you because, if you’re like most Americans, you have positive associations with fluoride. You may envision tooth protection, strong bones, and a government that cares about your dental needs. What you’ve probably never been told is that the fluoride added to drinking water and toothpaste is a crude industrial waste product of the aluminum and fertilizer industries, and a substance toxic enough to be used as rat poison. How is it that Americans have learned to love an environmental hazard? This phenomenon can be attributed to a carefully planned marketing program begun even before Grand Rapids, Michigan, became the first community to officially fluoridate its drinking water in 1945.(2) As a result of this ongoing campaign, nearly two-thirds of the nation has enthusiastically followed Grand Rapids’ example. But this push for fluoridation has less to do with a concern for America’s health than with industry’s penchant to expand at the expense of our nation’s well-being.

The first thing you have to understand about fluoride is that it’s the problem child of industry. Its toxicity was recognized at the beginning of the Industrial Revolution, when, in the 1850s iron and copper factories discharged it into the air and poisoned plants, animals, and people.(3) The problem was exacerbated in the 1920s when rapid industrial growth meant massive pollution. Medical writer Joel Griffiths explains that “it was abundantly clear to both industry and government that spectacular U.S. industrial expansion – and the economic and military power and vast profits it promised – would necessitate releasing millions of tons of waste fluoride into the environment.”(4)Their biggest fear was that “if serious injury to people were established, lawsuits alone could prove devastating to companies, while public outcry could force industry-wide government regulations, billions in pollution-control costs, and even mandatory changes in high-fluoride raw materials and profitable technologies.”(5)

Insecticide & Rat Poison are Good for You

At first, industry could dispose of fluoride legally only in small amounts by selling it to insecticide and rat poison manufacturers.(6) Then a commercial outlet was devised in the 1930s when a connection was made between water supplies bearing traces of fluoride and lower rates of tooth decay. Griffiths writes that this was not a scientific breakthrough, but rather part of a “public disinformation campaign” by the aluminum industry “to convince the public that fluoride was safe and good.” Industry’s need prompted Alcoa-funded scientist Gerald J. Cox to announce that “The present trend toward complete removal of fluoride from water may need some reversal.”(7)Griffiths writes:

“The big news in Cox’s announcement was that this ‘apparently worthless by-product’ had not only been proved safe (in low doses), but actually beneficial; it might reduce cavities in children. A proposal was in the air to add fluoride to the entire nation’s drinking water. While the dose to each individual would be low, ‘fluoridation’ on a national scale would require the annual addition of hundreds of thousands of tons of fluoride to the country’s drinking water.

Fluoride: Drink it and Like it!

“Government and industry – especially Alcoa – strongly supported intentional water fluoridation…[it] made possible a master public relations stroke – one that could keep scientists and the public off fluoride’s case for years to come. If the leaders of dentistry, medicine, and public health could be persuaded to endorse fluoride in the public’s drinking water, proclaiming to the nation that there was a ‘wide margin of safety,’ how were they going to turn around later and say industry’s fluoride pollution was dangerous?

“As for the public, if fluoride could be introduced as a health enhancing substance that should be added to the environment for the children’s sake, those opposing it would look like quacks and lunatics….

“Back at the Mellon Institute, Alcoa’s Pittsburgh Industrial research lab, this news was galvanic. Alcoa-sponsored biochemist Gerald J. Cox immediately fluoridated some lab rats in a study and concluded that fluoride reduced cavities and that ‘The case should be regarded as proved.’ In a historic moment in 1939, the first public proposal that the U.S. should fluoridate its water supplies was made – not by a doctor, or dentist, but by Cox, an industry scientist working for a company threatened by fluoride damage claims.”(8)

Once the plan was put into action, industry was buoyant. They had finally found the channel for fluoride that they were looking for, and they were even cheered on by dentists, government agencies, and the public. Chemical Week, a publication for the chemical industry, described the tenor of the times: “All over the country, slide rules are getting warm as waterworks engineers figure the cost of adding fluoride to their water supplies.” They are riding a trend urged upon them, by the U.S. Public Health Service, the American Dental Association, the State Dental Health Directors, various state and local health bodies, and vocal women’s clubs from coast to coast. It adds up to a nice piece of business on all sides and many firms are cheering the PHS and similar groups as they plump for increasing adoption of fluoridation.”(9)

Such overwhelming acceptance allowed government and industry to proceed hastily, albeit irresponsibly. The Grand Rapids experiment was supposed to take 15 years, during which time health benefits and hazards were to be studied. In 1946, however, just one year into the experiment, six more U.S. cities adopted the process. By 1947, 87 more communities were treated; popular demand was the official reason for this unscientific haste.The general public and its leaders did support the cause, but only after a massive government public relations campaign spearheaded by Edward L. Bernays, a nephew of Sigmund Freud. Bernays, a public relations pioneer who has been called “the original spin doctor,”(10) was a masterful PR strategist. As a result of his influence, Griffiths writes, “Almost overnight…the popular image of fluoride – which at the time was being widely sold as rat and bug poison – became that of a beneficial provider of gleaming smiles, absolutely safe, and good for children, bestowed by a benevolent paternal government. Its opponents were permanently engraved on the public mind as crackpots and right-wing loonies.”(11)
Griffiths explains that while opposition to fluoridation is usually associated with right-wingers, this picture is not totally accurate. He provides an interesting historical perspective on the anti-fluoridation stance:”Fluoridation attracted opponents from every point on the continuum of politics and sanity. The prospect of the government mass-medicating the water supplies with a well-known rat poison to prevent a nonlethal disease flipped the switches of delusionals across the country – as well as generating concern among responsible scientists, doctors, and citizens.

“Moreover, by a fortuitous twist of circumstances, fluoride’s natural opponents on the left were alienated from the rest of the opposition. Oscar Ewing, a Federal Security Agency administrator, was a Truman “fair dealer” who pushed many progressive programs such as nationalized medicine. Fluoridation was lumped with his proposals. Inevitably, it was attacked by conservatives as a manifestation of “creeping socialism,” while the left rallied to its support. Later during the McCarthy era, the left was further alienated from the opposition when extreme right-wing groups, including the John Birch Society and the Ku Klux Klan, raved that fluoridation was a plot by the Soviet Union and/or communists in the government to poison America’s brain cells.

“It was a simple task for promoters, under the guidance of the ‘original spin doctor,’ to paint all opponents as deranged – and they played this angle to the hilt….

“Actually, many of the strongest opponents originally started out as proponents, but changed their minds after a close look at the evidence. And many opponents came to view fluoridation not as a communist plot, but simply as a capitalist-style con job of epic proportions. Some could be termed early environmentalists, such as the physicians George L. Waldbott and Frederick B. Exner, who first documented government-industry complicity in hiding the hazards of fluoride pollution from the public. Waldbott and Exner risked their careers in a clash with fluoride defenders, only to see their cause buried in toothpaste ads.”(11)

By 1950, fluoridation’s image was a sterling one, and there was not much science could do at this point. The Public Health Service was fluoridation’s main source of funding as well as its promoter, and therefore caught in a fundamental conflict of interest.(12) If fluoridation were found to be unsafe and ineffective, and laws were repealed, the organization feared a loss of face, since scientists, politicians, dental groups, and physicians unanimously supported it.(13) For this reason, studies concerning its effects were not undertaken. The Oakland Tribune noted this when it stated that “public health officials have often suppressed scientific doubts” about fluoridation.(14)Waldbott sums up the situation when he says that from the beginning, the controversy over fluoridating water supplies was “a political, not a scientific health issue.”(15)

The Marketing of Fluoride Today

The marketing of fluoride continues. In a 1983 letter from the Environmental Protection Agency, then Deputy Assistant Administrator for Water, Rebecca Hammer, writes that the EPA “regards [fluoridation] as an ideal environmental solution to a long-standing problem. By recovering by-product fluosilicic acid from fertilizer manufacturing, water and air pollution are minimized and water utilities have a low-cost source of fluoride available to them.”(16) More recently, a 1992 policy statement from the Department of Health and Human Services says, “A recent comprehensive PHS review of the benefits and potential health risks of fluoride has concluded that the practice of fluoridating community water supplies is safe and effective.”(17)

Today, nearly 250 million people worldwide drink fluoridated water, including about 130 million Americans in 9600 communities. Out of the 50 largest cities in the US, 41 have fluoridated water.(18)

To help celebrate fluoride’s widespread use, the media recently reported on the 50th anniversary of fluoridation in Grand Rapids. Newspaper articles titled “Fluoridation: a shining public health success”(19) and “After 50 years, fluoride still works with a smile”(20) painted glowing pictures of the practice. Had investigators looked more closely, though, they might have learned that children in Muskegon, Michigan, an unfluoridated “control” city, had equal drops in dental decay. They might also have learned of the other studies that dispute the supposed wonders of fluoride.

The Fluoride Myth Doesn’t Hold Water

The big hope for fluoride was its ability to immunize children’s developing teeth against cavities. Rates of dental caries were supposed to plummet in areas where water was treated. Yet decades of experience and worldwide research have contradicted this expectation numerous times. Here are just a few examples:

  • In British Columbia, only 11% of the population drinks fluoridated water, as opposed to 40-70% in other Canadian regions. Yet British Columbia has the lowest rate of tooth decay in Canada. In addition, the lowest rates of dental caries within the province are found in areas that do not have their water supplies fluoridated.(21)
  • According to a Sierra Club study, people in unfluoridated developing nations have fewer dental caries than those living in industrialized nations. As a result, they conclude that “fluoride is not essential to dental health.”(22)
  • In 1986-87, the largest study on fluoridation and tooth decay ever was performed. The subjects were 39,000 school children between 5 and 17 living in 84 areas around the country. A third of the places were fluoridated, a third were partially fluoridated, and a third were not. Results indicate no statistically significant differences in dental decay between fluoridated and unfluoridated cities.(23)
  • A World Health Organization survey reports a decline of dental decay in western Europe, which is 98% unfluoridated. They state that western Europe’s declining dental decay rates are equal to and sometimes better than those in the U.S.(24)
  • A 1992 University of Arizona study yielded surprising results when they found that “the more fluoride a child drinks, the more cavities appear in the teeth.”(25)
  • Although all Native American reservations are fluoridated, children living there have much higher incidences of dental decay and other oral health problems than do children living in other U.S. communities.(26)

In light of all the evidence, fluoride proponents now make more modest claims. For example, in 1988, the ADA professed that a 40% to 60% cavity reduction could be achieved with the help of fluoride. Now they claim an 18% to 25% reduction. Other promoters mention a 12% decline in tooth decay.

Some former supporters are even beginning to question the need for fluoridation altogether. In 1990, a National Institute for Dental Research report stated that “it is likely that if caries in children remain at low levels or decline further, the necessity of continuing the current variety and extent of fluoride-based prevention programs will be questioned.”(27)

Most government agencies, however, continue to ignore the scientific evidence and to market fluoridation by making fictional claims about its benefits and pushing for its expansion. For instance, according to the U.S. Department of Health and Human Services, “National surveys of oral health dating back several decades document continuing decreases in tooth decay in children, adults and senior citizens. Nevertheless, there are parts of the country and particular populations that remain without protection. For these reasons, the U.S. PHS…has set a national goal for the year 2000 that 75% of persons served by community water systems will have access to optimally fluoridated drinking water; currently this figure is just about 60%. The year 2000 target goal is both desirable and yet challenging, based on past progress and continuing evidence of effectiveness and safety of this public health measure.”(17)

This statement is flawed on several accounts. First, as we’ve seen, research does not support the effectiveness of fluoridation for preventing tooth disease. Second, purported benefits are supposedly for children, not adults and senior citizens. At about age 13, any advantage fluoridation might offer comes to an end, and less than 1% of the fluoridated water supply reaches this population.(28) And third, fluoridation has never been proven safe. On the contrary, several studies directly link fluoridation to skeletal fluorosis, dental fluorosis, and several rare forms of cancer. This alone should frighten us away from its use.


Biological Safety Concerns

Only a small margin separates supposedly beneficial fluoride levels from amounts that are known to cause adverse effects. Dr. James Patrick, a former antibiotics research scientist at the National Institutes of Health, describes the predicament:

“[There is] a very low margin of safety involved in fluoridating water. A concentration of about 1 ppm is recommended…in several countries, severe fluorosis has been documented from water supplies containing only 2 or 3 ppm. In the development of drugs…we generally insist on a therapeutic index (margin of safety) of the order of 100; a therapeutic index of 2 or 3 is totally unacceptable, yet that is what has been proposed for public water supplies.”(29)

Other countries argue that even 1 ppm is not a safe concentration. Canadian studies, for example, imply that children under three should have no fluoride whatsoever. The Journal of the Canadian Dental Association states that “Fluoride supplements should not be recommended for children less than 3 years old.”(30) Since these supplements contain the same amount of fluoride as water does, they are basically saying that children under the age of three shouldn’t be drinking fluoridated water at all, under any circumstances. Japan has reduced the amount of fluoride in their drinking water to one-eighth of what is recommended in the U.S. Instead of 1 milligram per liter, they use less than 15 hundredths of a milligram per liter as the upper limit allowed. (31)

Even supposing that low concentrations are safe, there is no way to control how much fluoride different people consume, as some take in a lot more than others. For example, laborers, athletes, diabetics, and those living in hot or dry regions can all be expected to drink more water, and therefore more fluoride (in fluoridated areas) than others.(32) Due to such wide variations in water consumption, it is impossible to scientifically control what dosage of fluoride a person receives via the water supply.(33)

Another concern is that fluoride is not found only in drinking water; it is everywhere. Fluoride is found in foods that are processed with it, which, in the United States, include nearly all bottled drinks and canned foods.(34) Researchers writing in The Journal of Clinical Pediatric Dentistry have found that fruit juices, in particular, contain significant amounts of fluoride. In a recent study, a variety of popular juices and juice blends were analyzed and it was discovered that 42% of the samples examined had more than 1 ppm of fluoride, with some brands of grape juice containing much higher levels – up to 6.8 ppm! The authors cite the common practice of using fluoride-containing insecticide in growing grapes as a factor in these high levels, and they suggest that the fluoride content of beverages be printed on their labels, as is other nutritional information.(35)Considering how much juice some children ingest, and the fact that youngsters often insist on particular brands that they consume day after day, labeling seems like a prudent idea. But beyond this is the larger issue that this study brings up: Is it wise to subject children and others who are heavy juice drinkers to additional fluoride in their water?

Here’s a little-publicized reality: Cooking can greatly increase a food’s fluoride content. Peas, for example, contain 12 micrograms of fluoride when raw and 1500 micrograms after they are cooked in fluoridated water, which is a tremendous difference. Also, we should keep in mind that fluoride is an ingredient in pharmaceuticals, aerosols, insecticides, and pesticides.

And of course, toothpastes. It’s interesting to note that in the 1950s, fluoridated toothpastes were required to carry warnings on their labels saying that they were not to be used in areas where water was already fluoridated. Crest toothpaste went so far as to write: “Caution: Children under 6 should not use Crest.” These regulations were dropped in 1958, although no new research was available to prove that the overdose hazard no longer existed.(36)

Today, common fluoride levels in toothpaste are 1000 ppm. Research chemist Woodfun Ligon notes that swallowing a small amount adds substantially to fluoride intake.(36) Dentists say that children commonly ingest up to 0.5 mg of fluoride a day from toothpaste.(36)

This inevitably raises another issue: How safe is all this fluoride? According to scientists and informed doctors, such as Dr. John Lee, it is not safe at all. Dr. Lee first took an anti-fluoridation stance back in 1972, when as chairman of an environmental health committee for a local medical society, he was asked to state their position on the subject. He stated that after investigating the references given by both pro- and anti-fluoridationists, the group discovered three important things:

“One, the claims of benefit of fluoride, the 60% reduction of cavities, was not established by any of these studies. Two, we found that the investigations into the toxic side effects of fluoride have not been done in any way that was acceptable. And three, we discovered that the estimate of the amount of fluoride in the food chain, in the total daily fluoride intake, had been measured in 1943, and not since then. By adding the amount of fluoride that we now have in the food chain, which comes from food processing with fluoridated water, plus all the fluoridated toothpaste that was not present in 1943, we found that the daily intake of fluoride was far in excess of what was considered optimal.”(31)

What happens when fluoride intake exceeds the optimal? The inescapable fact is that this substance has been associated with severe health problems, ranging from skeletal and dental fluorosis to bone fractures, to fluoride poisoning, and even to cancer.

Skeletal Fluorosis

When fluoride is ingested, approximately 93% of it is absorbed into the bloodstream. A good part of the material is excreted, but the rest is deposited in the bones and teeth,(37) and is capable of causing a crippling skeletal fluorosis. This is a condition that can damage the musculoskeletal and nervous systems and result in muscle wasting, limited joint motion, spine deformities, and calcification of the ligaments, as well as neurological deficits. (38)

Large numbers of people in Japan, China, India, the Middle East, and Africa have been diagnosed with skeletal fluorosis from drinking naturally fluoridated water. In India alone, nearly a million people suffer from the affliction.(39) While only a dozen cases of skeletal fluorosis have been reported in the United States, Chemical and Engineering News states that “critics of the EPA standard speculate that there probably have been many more cases of fluorosis – even crippling fluorosis – than the few reported in the literature because most doctors in the U.S. have not studied the disease and do not know how to diagnose it.”(40)

Radiologic changes in bone occur when fluoride exposure is 5 mg/day, according to the late Dr. George Waldbott, author of Fluoridation: The Great Dilemma. While this 5 mg/day level is the amount of fluoride ingested by most people living in fluoridated areas,(41) the number increases for diabetics and laborers, who can ingest up to 20 mg of fluoride daily. In addition, a survey conducted by the Department of Agriculture shows that 3% of the U.S. population drinks 4 liters or more of water every day. If these individuals live in areas where the water contains a fluoride level of 4 ppm, allowed by the EPA, they are ingesting 16 mg/day from the consumption of water alone, and are thus at greater risk for getting skeletal fluorosis.(42)

Dental Fluorosis

According to a 1989 National Institute for Dental Research study, 1-2% of children living in areas fluoridated at 1 ppm develop dental fluorosis, that is, permanently stained, brown mottled teeth. Up to 23% of children living in areas naturally fluoridated at 4 ppm develop severe dental fluorosis.(43) Other research gives higher figures. The publication Health Effects of Ingested Fluoride, put out by the National Academy of Sciences, reports that in areas with optimally fluoridated water (1 ppm, either natural or added), dental fluorosis levels in recent years ranged from 8 to 51%. Recently, a prevalence of slightly over 80% was reported in children 12-14 years old in Augusta, Georgia.(43)

Fluoride is a noteworthy chemical additive in that its officially acknowledged benefit and damage levels are about the same. Writing in The Progressive, science journalist Daniel Grossman elucidates this point: “Though many beneficial chemicals are dangerous when consumed at excessive levels, fluoride is unique because the amount that dentists recommend to prevent cavities is about the same as the amount that causes dental fluorosis.”(44) Although the American Dental Association and the government consider dental fluorosis only a cosmetic problem, the American Journal of Public Health says that “…brittleness of moderately and severely mottled teeth may be associated with elevated caries levels.”(45) In other words, in these cases the fluoride is causing the exact problem that it’s supposed to prevent. Yiamouyiannis adds, “In highly naturally-fluoridated areas, the teeth actually crumble as a result. These are the first visible symptoms of fluoride poisoning.”(46)

Also, when considering dental fluorosis, there are factors beyond the physical that you can’t ignore – the negative psychological effects of having moderately to severely mottled teeth. These were recognized in a 1984 National Institute of Mental Health panel that looked into this problem.(44)

A telling trend is that TV commercials for toothpaste, and toothpaste tubes themselves, are now downplaying fluoride content as a virtue. This was noted in an article in the Sarasota/Florida ECO Report,(47) whose author, George Glasser, feels that manufacturers are distancing themselves from the additive because of fears of lawsuits. The climate is ripe for these, and Glasser points out that such a class action suit has already been filed in England against the manufacturers of fluoride-containing products on behalf of children suffering from dental fluorosis.

Bone Fractures

At one time, fluoride therapy was recommended for building denser bones and preventing fractures associated with osteoporosis. Now several articles in peer-reviewed journals suggest that fluoride actually causes more harm than good, as it is associated with bone breakage. Three studies reported in The Journal of the American Medical Association showed links between hip fractures and fluoride.(48-50) Findings here were, for instance, that there is “a small but significant increase in the risk of hip fractures in both men and women exposed to artificial fluoridation at 1 ppm.”(51) In addition, the New England Journal of Medicine reports that people given fluoride to cure their osteoporosis actually wound up with an increased nonvertebral fracture rate.(52) Austrian researchers have also found that fluoride tablets make bones more susceptible to fractures.(53)The U.S. National Research Council states that the U.S. hip fracture rate is now the highest in the world.(54)

Louis V. Avioli, professor at the Washington University School of Medicine, says in a 1987 review of the subject: “Sodium fluoride therapy is accompanied by so many medical complications and side effects that it is hardly worth exploring in depth as a therapeutic mode for postmenopausal osteoporosis, since it fails to decrease the propensity for hip fractures and increases the incidence of stress fractures in the extremities.”(54)

Fluoride Poisoning

In May 1992, 260 people were poisoned, and one man died, in Hooper Bay, Alaska, after drinking water contaminated with 150 ppm of fluoride. The accident was attributed to poor equipment and an unqualified operator.(55) Was this a fluke? Not at all. Over the years, the CDC has recorded several incidents of excessive fluoride permeating the water supply and sickening or killing people. We don’t usually hear about these occurrences in news reports, but interested citizens have learned the truth from data obtained under the Freedom of Information Act.

Here is a partial list of toxic spills we have not been told about:

July 1993 – Chicago, Illinois: Three dialysis patients died and five experienced toxic reactions to the fluoridated water used in the treatment process. The CDC was asked to investigate, but to date there have been no press releases.
May 1993 – Kodiak, Alaska (Old Harbor): The population was warned not to consume water due to high fluoride levels. They were also cautioned against boiling the water, since this concentrates the substance and worsens the danger. Although equipment appeared to be functioning normally, 22-24 ppm of fluoride was found in a sample.
July 1992 – Marin County, California: A pump malfunction allowed too much fluoride into the Bon Tempe treatment plant. Two million gallons of fluoridated water were diverted to Phoenix Lake, elevating the lake surface by more than two inches and forcing some water over the spillway.
December 1991 – Benton Harbor, Michigan: A faulty pump allowed approximately 900 gallons of hydrofluosilicic acid to leak into a chemical storage building at the water plant. City engineer Roland Klockow stated, “The concentrated hydrofluosilicic acid was so corrosive that it ate through more than two inches of concrete in the storage building.” This water did not reach water consumers, but fluoridation was stopped until June 1993. The original equipment was only two years old.
July 1991 – Porgate, Michigan: After a fluoride injector pump failed, fluoride levels reached 92 ppm and resulted in approximately 40 children developing abdominal pains, sickness, vomiting, and diarrhea at a school arts and crafts show.
November 1979 – Annapolis, Maryland: One patient died and eight became ill after renal dialysis treatment. Symptoms included cardiac arrest (resuscitated), hypotension, chest pain, difficulty breathing, and a whole gamut of intestinal problems. Patients not on dialysis also reported nausea, headaches, cramps, diarrhea, and dizziness. The fluoride level was later found to be 35 ppm; the problem was traced to a valve at a water plant that had been left open all night.(55)

Instead of addressing fluoridation’s problematic safety record, officials have chosen to cover it up. For example, the ADA says in one booklet distributed to health agencies that “Fluoride feeders are designed to stop operating when a malfunction occurs… so prolonged over-fluoridation becomes a mechanical impossibility.”(56) In addition, the information that does reach the population after an accident is woefully inaccurate. A spill in Annapolis, Maryland, placed thousands at risk, but official reports reduced the number to eight.(57) Perhaps officials are afraid they will invite more lawsuits like the one for $480 million by the wife of a dialysis patient who became brain-injured as the result of fluoride poisoning.

Not all fluoride poisoning is accidental. For decades, industry has knowingly released massive quantities of fluoride into the air and water. Disenfranchised communities, with people least able to fight back, are often the victims. Medical writer Joel Griffiths relays this description of what industrial pollution can do, in this case to a devastatingly poisoned Indian reservation:

“Cows crawled around the pasture on their bellies, inching along like giant snails. So crippled by bone disease they could not stand up, this was the only way they could graze. Some died kneeling, after giving birth to stunted calves. Others kept on crawling until, no longer able to chew because their teeth had crumbled down to the nerves, they began to starve….” They were the cattle of the Mohawk Indians on the New York-Canadian St. Regis Reservation during the period 1960-1975, when industrial pollution devastated the herd – and along with it, the Mohawks’ way of life….Mohawk children, too, have shown signs of damage to bones and teeth.”(58)

Mohawks filed suit against the Reynolds Metals Company and the Aluminum Company of America (Alcoa) in 1960, but ended up settling out of court, where they received $650,000 for their cows.(59)

Fluoride is one of industry’s major pollutants, and no one remains immune to its effects. In 1989, 155,000 tons were being released annually into the air,(60) and 500,000 tons a year were disposed of in our lakes, rivers, and oceans.(61)

Cancer

Numerous studies demonstrate links between fluoridation and cancer; however, agencies promoting fluoride consistently refute or cover up these findings.

In 1977, Dr. John Yiamouyiannis and Dr. Dean Burk, former chief chemist at the National Cancer Institute, released a study that linked fluoridation to 10,000 cancer deaths per year in the U.S. Their inquiry, which compared cancer deaths in the ten largest fluoridated American cities to those in the ten largest unfluoridated cities between 1940 and 1950, discovered a 5% greater rate in the fluoridated areas.(62) The NCI disputed these findings, since an earlier analysis of theirs apparently failed to pick up these extra deaths. Federal authorities claimed that Yiamouyiannis and Burk were in error, and that any increase was caused by statistical changes over the years in age, gender, and racial composition.(63)

In order to settle the question of whether or not fluoride is a carcinogen, a Congressional subcommittee instructed the National Toxicology Program (NTP) to perform another investigation.(64) That study, due in 1980, was not released until 1990. However, in 1986, while the study was delayed, the EPA raised the standard fluoride level in drinking water from 2.4 to 4 ppm.(65) After this step, some of the government’s own employees in NFFE Local 2050 took what the Oakland Tribune termed the “remarkable step of denouncing that action as political.”(66)

When the NTP study results became known in early 1990, union president Dr. Robert Carton, who works in the EPA’s Toxic Substances Division, published a statement. It read, in part: “Four years ago, NFFE Local 2050, which represents all 1100 professionals at EPA headquarters, alerted then Administrator Lee Thomas to the fact that the scientific support documents for the fluoride in drinking water standard were fatally flawed. The fluoride juggernaut proceeded as it apparently had for the last 40 years – without any regard for the facts or concern for public health.

“EPA raised the allowed level of fluoride before the results of the rat/mouse study ordered by Congress in 1977 was complete. Today, we find out how irresponsible that decision was. The results reported by NTP, and explained today by Dr. Yiamouyiannis, are, as he notes, not surprising considering the vast amount of data that caused the animal study to be conducted in the first place. The results are not surprising to NFFE Local 2050 either. Four years ago we realized that the claim that there was no evidence that fluoride could cause genetic effects or cancer could not be supported by the shoddy document thrown together by the EPA contractor.

“It was apparent to us that EPA bowed to political pressure without having done an in-depth, independent analysis, using in-house experts, of the currently existing data that show fluoride causes genetic effects, promotes the growth of cancerous tissue, and is likely to cause cancer in humans. If EPA had done so, it would have been readily apparent – as it was to Congress in 1977 – that there were serious reasons to believe in a cancer threat.

“The behavior by EPA in this affair raises questions about the integrity of science at EPA and the role of professional scientists, lawyers and engineers who provide the interpretation of the available data and the judgements (sic) necessary to protect the public health and the environment. Are scientists at EPA there to arrange facts to fit preconceived conclusions? Does the Agency have a responsibility to develop world-class experts in the risks posed by chemicals we are exposed to every day, or is it permissible for EPA to cynically shop around for contractors who will provide them the ‘correct’ answers?”(67) What were the NTP study results? Out of 130 male rats that ingested 45 to 79 ppm of fluoride, 5 developed osteosarcoma, a rare bone cancer. There were cases, in both males and females at those doses, of squamous cell carcinoma in the mouth.(68)Both rats and mice had dose-related fluorosis of the teeth, and female rats suffered osteosclerosis of the long bones.(69)

When Yiamouyiannis analyzed the same data, he found mice with a particularly rare form of liver cancer, known as hepatocholangiocarcinoma. This cancer is so rare, according to Yiamouyiannis, that the odds of its appearance in this study by chance are 1 in 2 million in male mice and 1in 100,000 in female mice.(39) He also found precancerous changes in oral squamous cells, an increase in squamous cell tumors and cancers, and thyroid follicular cell tumors as a result of increasing levels of fluoride in drinking water.(70)

A March 13, 1990, New York Times article commented on the NTP findings: “Previous animal tests suggesting that water fluoridation might pose risks to humans have been widely discounted as technically flawed, but the latest investigation carefully weeded out sources of experimental or statistical error, many scientists say, and cannot be discounted.”(71) In the same article, biologist Dr. Edward Groth notes: “The importance of this study…is that it is the first fluoride bioassay giving positive results in which the latest state-of-the-art procedures have been rigorously applied. It has to be taken seriously.”(71)

On February 22, 1990, the Medical Tribune, an international medical news weekly received by 125,000 doctors, offered the opinion of a federal scientist who preferred to remain anonymous:

“It is difficult to see how EPA can fail to regulate fluoride as a carcinogen in light of what NTP has found. Osteosarcomas are an extremely unusual result in rat carcinogenicity tests. Toxicologists tell me that the only other substance that has produced this is radium….The fact that this is a highly atypical form of cancer implicates fluoride as the cause. Also, the osteosarcomas appeared to be dose-related, and did not occur in controls, making it a clean study.”(72)

Public health officials were quick to assure a concerned public that there was nothing to worry about! The ADA said the occurrence of cancers in the lab may not be relevant to humans since the level of fluoridation in the experimental animals’ water was so high.(73) But the Federal Register, which is the handbook of government practices, disagrees: “The high exposure of experimental animals to toxic agents is a necessary and valid method of discovering possible carcinogenic hazards in man. To disavow the findings of this test would be to disavow those of all such tests, since they are all conducted according to this standard.”(73) As a February 5, 1990, Newsweek article pointed out, “such megadosing is standard toxicological practice. It’s the only way to detect an effect without using an impossibly large number of test animals to stand in for the humans exposed to the substance.”(74) And as the Safer Water Foundation explains, higher doses are generally administered to test animals to compensate for the animals’ shorter life span and because humans are generally more vulnerable than test animals on a body-weight basis.(75)

Several other studies link fluoride to genetic damage and cancer. An article in Mutation Research says that a study by Proctor and Gamble, the very company that makes Crest toothpaste, did research showing that 1 ppm fluoride causes genetic damage.(76) Results were never published but Proctor and Gamble called them “clean,” meaning animals were supposedly free of malignant tumors. Not so, according to scientists who believe some of the changes observed in test animals could be interpreted as precancerous.(77) Yiamouyiannis says the Public Health Service sat on the data, which were finally released via a Freedom of Information Act request in 1989. “Since they are biased, they have tried to cover up harmful effects,” he says. “But the data speaks for itself. Half the amount of fluoride that is found in the New York City drinking water causes genetic damage.”(46)

A National Institutes of Environmental Health Sciences publication, Environmental and Molecular Mutagenesis, also linked fluoride to genetic toxicity when it stated that “in cultured human and rodent cells, the weight of evidence leads to the conclusion that fluoride exposure results in increased chromosome aberrations.”(78) The result of this is not only birth defects but the mutation of normal cells into cancer cells. The Journal of Carcinogenesis further states that “fluoride not only has the ability to transform normal cells into cancer cells but also to enhance the cancer-causing properties of other chemicals.”(79)

Surprisingly, the PHS put out a report called Review of fluoride: benefits and risks, in which they showed a substantially higher incidence of bone cancer in young men exposed to fluoridated water compared to those who were not. The New Jersey Department of Health also found that the risk of bone cancer was about three times as high in fluoridated areas as in nonfluoridated areas.(46)

Despite cover-up attempts, the light of knowledge is filtering through to some enlightened scientists. Regarding animal test results, the director of the U.S. National Institute of Environmental Health Sciences, James Huff, does say that “the reason these animals got a few osteosarcomas was because they were given fluoride…Bone is the target organ for fluoride.”(80) Toxicologist William Marcus adds that “fluoride is a carcinogen by any standard we use. I believe EPA should act immediately to protect the public, not just on the cancer data, but on the evidence of bone fractures, arthritis, mutagenicity, and other effects.”(81)

The Challenge of Eliminating Fluoride

Given all the scientific challenges to the idea of the safety of fluoride, why does it remain a protected contaminant? As Susan Pare of the Center for Health Action asks, “…even if fluoride in the water did reduce tooth decay, which it does not, how can the EPA allow a substance more toxic than Alar, red dye #3, and vinyl chloride to be injected purposely into drinking water?”(82)

This is certainly a logical question and, with all the good science that seems to exist on the subject, you would think that there would be a great deal of interest in getting fluoride out of our water supply. Unfortunately, that hasn’t been the case. As Dr. William Marcus, a senior science advisor in the EPA’s Office of Drinking Water, has found, the top governmental priority has been to sweep the facts under the rug and, if need be, to suppress truth-tellers. Marcus explains(83) that fluoride is one of the chemicals the EPA specifically regulates, and that he was following the data coming in on fluoride very carefully when a determination was going to be made on whether the levels should be changed. He discovered that the data were not being heeded. But that was only the beginning of the story for him. Marcus recounts what happened:

“The studies that were done by Botel Northwest showed that there was an increased level of bone cancer and other types of cancer in animals….in that same study, there were very rare liver cancers, according to the board-certified veterinary pathologists at the contractor, Botel. Those really were very upsetting because they were hepatocholangeal carcinomas, very rare liver cancers….Then there were several other kinds of cancers that were found in the jaw and other places.

“I felt at that time that the reports were alarming. They showed that the levels of fluoride that can cause cancers in animals are actually lower than those levels ingested in people (who take lower amounts but for longer periods of time).

“I went to a meeting that was held in Research Triangle Park, in April 1990, in which the National Toxicology Program was presenting their review of the study. I went with several colleagues of mine, one of whom was a board-certified veterinary pathologist who originally reported hepatocholangeal carcinoma as a separate entity in rats and mice. I asked him if he would look at the slides to see if that really was a tumor or if the pathologists at Botel had made an error. He told me after looking at the slides that, in fact, it was correct.

“At the meeting, every one of the cancers reported by the contractor had been downgraded by the National Toxicology Program. I have been in the toxicology business looking at studies of this nature for nearly 25 years and I have never before seen every single cancer endpoint downgraded…. I found that very suspicious and went to see an investigator in the Congress at the suggestion of my friend, Bob Carton. This gentleman and his staff investigated very thoroughly and found out that the scientists at the National Toxicology Program down at Research Triangle Park had been coerced by their superiors to change their findings.”(83)

Once Dr. Marcus acted on his findings, something ominous started to happen in his life: “…I wrote an internal memorandum and gave it to my supervisors. I waited for a month without hearing anything. Usually, you get a feedback in a week or so. I wrote another memorandum to a person who was my second-line supervisor explaining that if there was even a slight chance of increased cancer in the general population, since 140 million people were potentially ingesting this material, that the deaths could be in the many thousands. Then I gave a copy of the memorandum to the Fluoride Work Group, who waited some time and then released it to the press.

“Once it got into the press all sorts of things started happening at EPA. I was getting disciplinary threats, being isolated, and all kinds of thingswhich (sic) ultimately resulted in them firing me on March 15, 1992.”(83)

In order to be reinstated at work, Dr. Marcus took his case to court. In the process, he learned that the government had engaged in various illegal activities, including 70 felony counts, in order to get him fired. At the same time, those who committed perjury were not held accountable for it. In fact, they were rewarded for their efforts:

“When we finally got the EPA to the courtroom…they admitted to doing several things to get me fired. We had notes of a meeting…that showed that fluoride was one of the main topics discussed and that it was agreed that they would fire me with the help of the Inspector General. When we got them on the stand and showed them the memoranda, they finally remembered and said, oh yes, we lied about that in our previous statements.

“Then…they admitted to shredding more than 70 documents that they had in hand – Freedom of Information requests. That’s a felony…. In addition, they charged me with stealing time from the government. They…tried to show…that I had been doing private work on government time and getting paid for it. When we came to court, I was able to show that the time cards they produced were forged, and forged by the Inspector General’s staff….”(83)

For all his efforts, Dr. Marcus was rehired, but nothing else has changed: “The EPA was ordered to rehire me, which they did. They were given a whole series of requirements to be met, such as paying me my back pay, restoring my leave, privileges, and sick leave and annual leave. The only thing they’ve done is put me back to work. They haven’t given me any of those things that they were required to do.”(83)

What is at the core of such ruthless tactics? John Yiamouyiannis feels that the central concern of government is to protect industry, and that the motivating force behind fluoride use is the need of certain businesses to dump their toxic waste products somewhere. They try to be inconspicuous in the disposal process and not make waves. “As is normal, the solution to pollution is dilution. You poison everyone a little bit rather than poison a few people a lot. This way, people don’t know what’s going on.”(46)

Since the Public Health Service has promoted the fluoride myth for over 50 years, they’re concerned about protecting their reputation. So scientists like Dr. Marcus, who know about the dangers, are intimidated into keeping silent. Otherwise, they jeopardize their careers. Dr. John Lee elaborates: “Back in 1943, the PHS staked their professional careers on the benefits and safety of fluoride. It has since become bureaucratized. Any public health official who criticizes fluoride, or even hints that perhaps it was an unwise decision, is at risk of losing his career entirely. This has happened time and time again. Public health officials such as Dr. Gray in British Columbia and Dr. Colquhoun in New Zealand found no benefit from fluoridation. When they reported these results, they immediately lost their careers…. This is what happens – the public health officials who speak out against fluoride are at great risk of losing their careers on the spot.”(31)

Yiamouyiannis adds that for the authorities to admit that they’re wrong would be devastating. “It would show that their reputations really don’t mean that much…. They don’t have the scientific background. As Ralph Nader once said, if they admit they’re wrong on fluoridation, people would ask, and legitimately so, what else have they not told us right?”(46)

Accompanying a loss in status would be a tremendous loss in revenue. Yiamouyiannis points out that “the indiscriminate careless handling of fluoride has a lot of companies, such as Exxon, U.S. Steel, and Alcoa, making tens of billions of dollars in extra profits at our expense…. For them to go ahead now and admit that this is bad, this presents a problem, a threat, would mean tens of billions of dollars in lost profit because they would have to handle fluoride properly. Fluoride is present in everything from phosphate fertilizers to cracking agents for the petroleum industry.”(46)

Fluoride could only be legally disposed of at a great cost to industry. As Dr. Bill Marcus explains, “There are prescribed methods for disposal and they’re very expensive. Fluoride is a very potent poison. It’s a registered pesticide, used for killing rats or mice…. If it were to be disposed of, it would require a class-one landfill. That would cost the people who are producing aluminum or fertilizer about $7000+ per 5000- to 6000-gallon truckload to dispose of it. It’s highly corrosive.”(83)

Another problem is that the U.S. judicial system, even when convinced of the dangers, is powerless to change policy. Yiamouyiannis tells of his involvement in court cases in Pennsylvania and Texas in which, while the judges were convinced that fluoride was a health hazard, they did not have the jurisdiction to grant relief from fluoridation. That would have to be done, it was ultimately found, through the legislative process.(46) Interestingly, the judiciary seems to have more power to effect change in other countries. Yiamouyiannis states that when he presented the same technical evidence in Scotland, the Scottish court outlawed fluoridation based on the evidence.(46)

Indeed, most of western Europe has rejected fluoridation on the grounds that it is unsafe. In 1971, after 11 years of testing, Sweden’s Nobel Medical Institute recommended against fluoridation, and the process was banned. The Netherlands outlawed the practice in 1976, after 23 years of tests. France decided against it after consulting with its Pasteur Institute(64) and West Germany, now Germany, rejected the practice because the recommended dosage of 1 ppm was “too close to the dose at which long-term damage to the human body is to be expected.”(84) Dr. Lee sums it up: “All of western Europe, except one or two test towns in Spain, has abandoned fluoride as a public health plan. It is not put in the water anywhere. They all established test cities and found that the benefits did not occur and the toxicity was evident.”(31)

Isn’t it time the United States followed western Europe’s example? While the answer is obvious, it is also apparent that government policy is unlikely to change without public support. We therefore must communicate with legislators, and insist on one of our most precious resources – pure, unadulterated drinking water. Yiamouyiannis urges all American people to do so, pointing out that public pressure has gotten fluoride out of the water in places like Los Angeles; Newark and Jersey City in New Jersey; and Bedford, Massachusetts.(46) He emphasizes the immediacy of the problem: “There is no question with regard to fluoridation of public water supplies. It is absolutely unsafe…and should be stopped immediately. This is causing more destruction to human health than any other single substance added purposely or inadvertently to the water supply. We’re talking about 35,000 excess deaths a year…10,000 cancer deaths a year…130 million people who are being chronically poisoned. We’re not talking about dropping dead after drinking a glass of fluoridated water…. It takes its toll on human health and life, glass after glass.”(46)

There is also a moral issue in the debate that has largely escaped notice. According to columnist James Kilpatrick, it is “the right of each person to control the drugs he or she takes.” Kilpatrick calls fluoridation compulsory mass medication, a procedure that violates the principles of medical ethics.(13) A recent New York Times editorial agrees:

“In light of the uncertainty, critics [of fluoridation] argue that administrative bodies are unjustified in imposing fluoridation on communities without obtaining public consent…. The real issue here is not just the scientific debate. The question is whether any establishment has the right to decide that benefits outweigh risks and impose involuntary medication on an entire population. In the case of fluoridation, the dental establishment has made opposition to fluoridation seem intellectually disreputable. Some people regard that as tyranny.”(85)

Fluoride: Poison or Panacea?

by Gene Eberts, Ph.D., Health Psychologist

Here is the question.

Are you slowly killing yourself and your children with one of the most toxic substances on Earth, or merely benefiting from a substance that the American Dental Association (ADA), the National Academy of Sciences (NAS) and the Environmental Protection Agency (EPA) claims is a safe and effective way to reduce cavities?

If you are like most people, you would probably vote for “safe and effective.” After all it has been added to our public water supply for almost 50 years; how bad could it be?

Well… have you read the back of a tube of toothpaste lately? On the back of every tube you will find a warning from the Food and Drug Administration (FDA) to, “keep out of the reach of children and contact poison control if accidentally swallowed.” So how safe is this fluoride that is protecting us from cavities?

Investigating the Health Effects of Fluoride

In may of 2001, the U.S. Congress expanded its probe into the health effects of the fluoridation (adding fluoride) of public water systems. This controversial issue is far from dead.

Opponents of fluoride have concluded that fluoride does not prevent cavities and that it is dangerous to public health. Supporters of fluoride including the ADA, the NAS and the EPA would have you believe that all opponents of fluoride are half-crazed, muddle-brained, right-wing idiots who don’t know the first thing about real science. While neither side may be completely right, the scientific evidence is beginning to stack up against fluoride.

The Evidence Against Fluoride

In the United States the rate of cavities in children has been declining for at least the past 70 years. However, the addition of fluoride to public drinking water and toothpaste has had no discernable effect on this rate of decline.

Several recent scientific reports, including a comprehensive study of 39,000 school children have failed to show any difference in cavity rates in fluoridated vs. non-fluoridated communities.

Studies in the Journal of Dental Research recently concluded that rates of tooth decay have declined as much in Western Europe as they have in the United States in recent decades. The problem is that Western Europe is 98% non-fluoridated.

Both the Pasteur Institute and the Nobel Institute oppose fluoridation and as a result most Western European nations, including Germany, France, Sweden and Holland prohibit fluoride.

Even if all of these studies were flawed, and I have mentioned only a few of hundreds of studies that are out there, and even if we conclude that fluoride does protect against cavities, there is still one glaring problem with ingesting fluoride – fluoride overdoese.

Fluoride overdose

We have been dumping fluoride into our public water systems for almosts 50 years. This has created what is now called the “multiplier effect.” Fluoride from our drinking water is transferred during manufacturing into processed food and beverages. For example, a 12 ounce can of Coke contains 1/3rd of the recommended Total Daily Amount of fluoride.

In 1991, the U.s. Health and Human Services agency reported that even non-fluoridated communities get 1 to 2 times the

recommended amount of fluoride and fluoridated communities were overdosing on as much as 7 times the recommended amount of total daily fluoride intake.

This overdosing is the most likely cause of the only significant difference in dental health found between fluoridated and non-fluoridated communities: Fluoridated communities show almost double the incidence of dental Fluoridosis.

Dental Fluoridosis, caused by ingesting an overdose of fluoride, is a condition in which the cells that lay down tooth enamel are poisoned. In less severe cases the damage shows up as chalky white areas on the teeth. In more severe cases the teeth exhibit yellow, brown and black stains and pitting of the enamel. Eventually this structural weakness leads to breakage of the tips of the teeth.

There are studies that support the cavity fighting effects of fluoride. After all, fluoride is a poison and it will kill the cavity creating bacteria that infect the teeth. However, most leading dental researchers also agree that the benefits of fluoride come from the tropical application of fluoride, not the ingestion (eating or drinking) of it.

The Side Effects of Fluoride and its’ Contaminants

Another lesser known aspect of the controversy over fluoride has to do with the source of the fluoride itself.

To maintain scientific control over the dosage, practically every clinical experiment on the effects of fluoride has used pharmaceutical grade sodium fluoride. But more than 90% of the fluoride added to public water supplied in this country is extracted from the waste water collected in the smokestack scrubbers used by the phosphate fertilizer industry. This toxic waste contains lead, cadmium, arsenic, radium and other poisonous substances. By law this toxic waste could not be dumped into rivers, lakes or the sea, but it is added to our public water supply.

The picture is even bleaker when we turn to the safety of fluoride itself. Scientific evidence from around the world continues to link fluoride to severe health risks. If these studies were reporting high doses of fluoride this would not be surprising. After all, fluoride is second to arsenic in toxicity and more toxic than lead. Among its other uses, fluoride has been quite effective in killing bugs and rats.

What is shocking is that these studies report on fluoride use that is equal to or less than the amounts commonly placed in our public drinking water. Chronic fluoride use has been linked to bone cancer, kidney cancer, Alzheimer’s, hip fractures in the elderly and other health problems.

The Union of scientists at the EPA wrote a white paper (a short authoritative report or treatise prepared to educate readers about a specific topic) outlining why scientist members working at the EPA oppose drinking water fluoridation. The following is a quote from that paper.

“…our opposition to drinking water fluoridation has grown, based on the scientific literature documenting the increasingly out-of-control exposures to fluoride, the lack of benefit to dental health from ingestion of fluoride and the hazards to human health from such ingestion. These hazards include acute toxic hazard, such as to people with impairred kidney function, as well as chronic toxic hazards of gene mutations, cancer, neurotoxicity, bone pathology and dental fluorosis.”

Conclusion

The final chapter in this controversy about the health effects fluoride hasn’t been written yet, but my advice is: why take the chance? At least 12 Nobel Prize winners in the fields of chemistry and medicine (you know, those “idiots who don’t know the first thing about real science”) have expressed reservation about using fluoride in public water systems. Why expose yourself to this toxic substanvce anymore than you have to?

Our Position on Fluoride

You probably have not even considered that fluoride has any effects other than beneficial. Anyone born after World War Ii has been educated about the beneficial effects of fluoride to reduce dental cavities. After all, fluoride is placed in our water and in our toothpastes as well as applied to our teeth when we visit the dentist.

But – Have you read the back of the tube of toothpaste lately? There’s a warning from the Food and Drug Administration – “keep out of the reach of children and contact poison control if accidentally swallowed.” How safe is this fluoride that is protecting us from cavities? Would you be surprised to find out fluoride is second to arsenic in toxicity and more toxic than lead?

There are scientific studies to correlate a link between fluoride and an increase in hip fractures as well as bone cancer. The most noted study, done in New York, compared two communities over an extended number of years — one with fluoride, one without.

The conclusion: no evidence that fluoride reduced the number of cavities.

A survey in British Columbia reported the highest cavity rates occurred in the provinces that were totally on unfluoridated.

Also it has been clearly demonstrated that over ingestion of fluoridated water causes dental fluorosis or mottling. This is evidenced by chalky white areas on teeth and in advanced cases the teeth exhibit yellow, brown and black stains, pitting of the enamel, and breaking of the tips of teeth.

So, if there are no clinical studies to prove fluoride prevents cavities, and there are potential damaging health effects from fluoride, and may cause mottling of the teeth, why are we exposing ourselves and our children to this?

We have not been given the choice in our drinking water but we can drink filtered or ionized water. We also have a choice not to use fluoride toothpastes or to avoid fluoride treatment from our dentist.

How concerned is the Institute about the possible negative health effects of fluoride? We could earn at least an extra $100,000 each year by giving fluoride treatments. That’s almost two million dollars in extra income the Institute has given up over the past twenty years. If that’s not commitment, what is?

If you want to believe this is just my opinion, research for yourself – you owe it to yourself and your children.

Multiple Sclerosis

Heavy Metal Poisoning

By Gary P. Owen

MS and mercury poisoning is something that rears its head from time to time and needs to be taken seriously. The substances in the blood harmful to nerves are kept separate by a special filtering layer in the walls of blood vessels called the endothelium. This is particularly important in the brain where the filter mechanism is known as the blood brain barrier.

Any number of life events can cause this barrier to be breached, including stress, tiredness, fever, emotional upset, heat, injury and eating too much fat. This allows chemicals from the blood which are poisonous to the nervous system into the brain where they can cause serious damage. Heavy metals such as mercury, cadmium, and aluminum are well-known examples of such potent neurotoxins.

Some researchers now believe that MS is a direct result of neurotoxins from the blood entering the central nervous system through the brain and some researchers claim they have found mercury levels more than seven times higher than normal in the spinal fluid of people with MS. This research lays the blame on the high amounts of mercury used in routine dental fillings and indeed some countries have now already banned the use of mercury fillings.

Shortly after I was diagnosed with MS I made a decision to have all of my mercury fillings removed because of articles I had read which linked MS and mercury. I had quite a lot of them and it took several visits to the dentist to have them all removed and replaced with white fillings. The dentist could only remove two at a time because to remove any more would have introduced too much mercury to my system at the one time. This surprised me because I had this dangerous substance in my mouth for a number of years, and was never made aware when I was getting them of the potential dangers. I now insist and pay extra to ensure that my children do not get mercury fillings and it might be something that you want to consider as well.

A few months after having the fillings removed I did begin to feel slightly better but at the same time I also embarked on a brand new diet. I took control of my MS and decided that I was going to control it rather than it control me.

I have greatly benefits from a book which has examined the link between what we eat and multiple sclerosis. If you would like to know what foods are attacking your body, what supplements you must take and how to create the energy that you need, then this book is a must read. Reverse Multiple Sclerosis

I am not a doctor nor am I qualified in medicine in any way. These are things that have worked for me in controlling my MS. Before undertaking any diet or fitness regime you should always consult your physician first.

Thanks for reading,

Chronic Fatigue

Chronic fatigue is one of the main reasons people go to a health practitioner and it is one of the hardest illnesses to tolerate. Lacking energy and mental alertness means you don’t feel like doing anything, which in turn makes you feel worse and consequently you don’t sleep well. Fatigue is the most common complaint stated by patients in my dental practice. Which is why I began looking for a connection between mercury amalgam and chronic fatigue.

You may not be aware that the silver amalgam fillings in your teeth are actually fifty percent mercury or that this mercury is highly toxic. There is a mass of scientific evidence that clearly demonstrates that mercury can leak from the amalgam fillings in your mouth and harm the body.

The World Health Organization recognizes that dental amalgam contaminates the human body and has made recommendations regarding safe levels of mercury in food. Yet this highly dangerous material is placed in your mouth because traditional dentists believe it to be a safe and stable substance once mixed.

Double Jeopardy

Interestingly enough, “silver” amalgams not only present a danger from mercury. The other fifty percent of metals in the composite are silver, tin, copper and zinc. When you put these metals into the mouth surrounded by saliva it has a battery effect. The battery effect creates an electrical current that can disrupt the nervous system and normal flow of energy to the body. This is one of the reasons why a person may experience fatigue.

Many countries worldwide have looked closely at the science behind this practice and many places in Europe and Canada have banned the use of mercury. It’s beginning to happen here in the USA, but it’s taking a little longer. However, in the UK, mercury fillings are the norm for national health patients.

From my experience as a dental practitioner, I believe that many of today’s so called “mystery syndromes” like chronic fatigue may not actually be so mysterious, but related to mercury amalgams. Physicians often bunch chronic fatigue together with recurrent depression, fibromyalgia and anorexia as supposedly incurable conditions. Basically they do not know how to treat them and many people suffer unnecessarily.

For more than twenty years I have treated patients with “silver” fillings without realizing the potential dangers of filling teeth with mercury. However, chronic fatigue seems to be such a common physical complaint that I started to wonder if there is a connection. It’s clear to me that there is no environmental cause and effect, as these people didn’t all live in the same house, work at the same job or eat the same food.

Obviously, diet, exercise or lack of it can be contributing factors, but what became really clear to me was that most of these patients have had dental amalgams at one point in their life, if not currently.

I’ve had clients come to me with a history of being very active. They took part in athletic activities, even marathon runners, yet over a period of time they became more and more fatigued, whereas others experience fatigue shortly after having dental work done.

You are probably wondering why the dental profession is not open to the idea that mercury is a toxic metal that should not be put in the mouth, so before going further I will give you a little background.

History of Mercury and the Dental Associations

Mercury has historically been used as an antiseptic (mercurial/mercurochrome), to kill bacteria in the treatment of some diseases. Its use in dentistry dates back to the eighteen hundreds when the governing body of dentists was the International Society of Dental Surgeons. In those days you could either have your teeth filled with gold, extracted or endure toothache and its consequences. The problem was that gold was far too expensive for most people.

It was as this point of time that two brothers introduced the concept of mercury, other wise known as quacksilber (German for quicksilver). This amalgam of silver and mercury could be shapes by hand, was easily installed in the tooth and was a great deal cheaper than gold.

The governing body of International Society of Dental Surgeons actually made a bylaw stating that dentists using this material could no longer belong to the organization. However, dentists of the time decided this was a viable option for treating and filling teeth, despite there being overwhelming evidence of its toxicity.

It was also no secret that hat makers were developing neurological problems. In fact “mad hatter syndrome” was well known, yet these dentists decided to go off on their own and formed the American Dental Association and became first to patent mercury fillings.

This is not to say that the American Dental Association’s intentions are malevolent. But when they started the first dental school, this became part of the education, as they were not willing to look at the science. From a psychological perspective it’s easy to see why they would want to protect their profession, as it’s very hard for anyone to admit they have been poisoning their clients for more than fifty years.

When You Remove The Mercury

Previously, I stated that the most common condition my patients report to me is chronic fatigue and that it’s clear to me that this is multi-factorial. Mercury fillings are yet another facet and I started to investigate what was the big deal about this. It soon became evident that mercury affects every system and every cell in the body. Of course this is dependent on what else is going on in people’s lives, how stressed they are and the diet they eat.

The average patient comes to my practice presenting chronic fatigue, not necessarily chronic fatigue syndrome, but some tiredness and not feeling up to doing all that they want to do in life. After removing mercury amalgams from patient’s mouths and filling with a non-toxic substance, the most common improvement in health was that they had more energy.

Over and over again I have seen so many symptoms improve after removing the amalgam fillings – skin rashes heal, muscles are less stressed, headaches go away and I can see the changes in their face. Most people really notice the difference and say how much more alive they feel.

I’ve had numerous patients who, all of a sudden, get their life back after having only one amalgam removed, even if they have four quadrants (all upper, lower, right and left) with fillings.

I always caution them to take it easy and allow the body to heal itself properly, but all of a sudden they are able to do things they haven’t been able to do for so long. So they are out there riding their bikes, playing with their children or mowing the lawn because they suddenly just felt better.

Science points to a connection between mercury poisoning and chronic fatigue.

This is not so hard to understand from a more scientific viewpoint, as it is known that mercury affects all the major organs. It can attack the thyroid gland, which makes people lethargic, sluggish, often tired and lacking energy. Mercury will displace the active thyroid hormone and may even attach to the thyroid gland and make it inactive.

This means when you are tested you may have plenty of thyroid hormone, but the mercury may be preventing it from being active. As it can embed itself in tissue, it may attach and destroy the organ itself leaving you with not thyroid function. The same thing can happen to the pituitary gland, which releases the thyroid-stimulating hormone, again affecting the thyroid.

This in turn could affect the adrenal glands so that less cortisol and adrenaline are released for energy. Circulation is affected because there is a displacement in the iron group, the heme in the hemoglobin, so that it is unable to carry oxygen efficiently, which affects the heart and will create fatigue.

The Immune System

As well as having an effect on the red blood cells and their ability to carry oxygen, mercury can attack the white blood cells (lymphocytes) and affect the immune system.

When these cells that are needed to defend your body are not functioning, an autoimmune disease will occur and the body will attack itself.

This means your body will be less able to fight other infections, which places even more stress on the body.

The Future of Dentistry

I believe it is important that as many people as possible learn about the dangers of mercury amalgam and chronic fatigue. It is not possible to definitely state that removing your fillings will improve chronic fatigue, but this is the result in most cases.

Just one word of caution here, if you are thinking of having your amalgam fillings removed, choose your dentist carefully. A biological dentist will take great care to ensure safe removal of your mercury fillings, whereas a cosmetic or traditional dentist may not have the correct instruments or safety protocol to prevent contamination.

With there being such a split between mainstream and alternative dentistry, you are not always presented with the truth, so I advise keeping an open mind and seeking out as much information as you can possibly find, as your health, perhaps even your life, depends on it.

Teen Charged with Mercury Spill

Teen Charged With Cardozo Mercury Spill

By: Tarran Lively – The Washington Times – February 27, 2005

A 16-year old boy was arrested yesterday afternoon in connection with the mercury contamination of Cardozo High School in Northwest. The teen was taken into custody at about 5 p.m. and charged with illegal dumping of a hazardous material, said D.C. police spokesman Sgt. Joe Gentile. It wasn’t known whether the boy is a student at Cardozo, but he was arrested after police identified possible suspects from a school surveillance video. The investigation is ongoing, Sgt. Gentile Said.

Authorities tested two homes in which investigators believe the mercury may have been kept before it was spilled at the school on Wednesday. Mercury vapors were found in one home, in the 3600 block of Warder Street NW, in the Petworth neighborhood. Authorities evacuated the home of 13 persons, who ranged in age from 18 months to about 60 years. None of the residents tested positive for mercury contamination, but clothing in one of the closets tested positive for mercury, said Dr. Greg Payne, the city’s health director. The crews also tested a home in the 600 block of Irving Street NW. It was not clear where the student suspected of spreading the mercury lived. Cardozo, at 13th and Clifton streets, has been closed since hazardous-materials crews found about 2 ounces of mercury in three places inside the school, including the back of a stairwell on the first floor. Cardozo Principal Reginald Ballard Jr. said last week no mercury was stored in the school. He also said the mercury was likely smuggled in by a “prankster.” D.C. schools Superintendent Clifford B. Janey called the contamination a “dangerous situation.” About 600 students and 150 staff and faculty members were screened, and at least 15 persons had traces of the metallic element on their clothing.

Some students who left the building before they could be tested were examined yesterday, and all were cleared of any contamination, health officials said. The school is being cleaned and an announcement is expected today on when it will reopen. In fall 2003, students at Ballou High School in Southeast found mercury in an unlocked cabinet and threw it at walls and at each other. The contamination forced city officials to close the school for more than a month. The cleanup cost more than $1 million. The Environmental Protection Agency screened about 1,200 people and 86 homes after the students brought the toxic metal onto a Metro bus and into many of their homes. A 16-year-old Ballou High School student was arrested in the theft of the vial of mercury.

More on Mercury

  • TUNA TYPES- One particularly common source of low-level mercury exposure is tuna. Because they are large, long-lived predators, tuna accumulate more mercury in their tissue than smaller, short-lived fish. When tested for mercury – in parts per million, flesh from albacore tuna, which take five years to mature, was shown to contain about four times as much mercury as chunk light tuna, which is harvested from younger fish.
  • HISTORY– Mercury was known to the ancient Chinese and Hindus; the element has been found in Egyptian tombs from 1500 B.C.
  • SOURCE– Mercury rarely occurs free in nature but can be found in ores, principally cinnabar. The element, which exists in its natural form as a mix of seven stable isotopes, is most often found near volcanoes or geothermal springs. The metal is obtained by heating cinnabar in an air current and condensing the vapor.
  • USES– Mercury easily forms alloys, called amalgams, with other metals like gold, silver, and tin. The element has many uses in the chemical industry, such as in the manufacture of sodium hydroxide and chlorine by the electrolysis of brine, as well as in making advertising signs, mercury switches, and other electrical apparatuses. It is also used to make sensitive measuring devices for laboratories. Other uses are in dental work, batteries, and catalysts. Because of mercury’s toxicity, many of these uses are under review.
  • FAVORED FISH- An inspector at a California cannery in 1953 spot-checks canned tuna. In the United States, canned tuna is the third most commonly purchased food item, after sugar and coffee, based on dollar sales per amount of shelf space devoted to the product. An EPA study reported the median amount of mercury, measured in parts per million, in the following varieties of canned tuna: chunk light: .08 parts per million; canned albacore tuna: .34ppm; fresh or frozen tuna: .30ppm. A 2004 EPA advisory mentions five types of fish and shellfish that are low in mercury: shrimp, canned light tuna, salmon, pollack, and catfish. The advisory also warns consumers not to eat shark, swordfish, king mackerel, and tilefish because they all contain high levels of mercury.
  • MERCURY FILLINGS- Dental amalgams, known as silver fillings, are composed of roughly 50 percent mercury. Studies of people with mercury-containing dental fillings show a correlation between the number and size of the fillings and the amount of mercury excreted in their urine. The relationship suggests that the mercury is derived from mercury vapor released from the fillings. Some evidence shows that the level of mercury in the brain tissue of fetuses, newborns, and young children is also directly proportional to the number of surfaces of amalgam fillings the mother has.
  • TESTING TROUBLE- Chronic low-level exposure to mercury is difficult to quantify because analyses of blood, urine, and hair will reflect only recent acute exposure, not past exposure. If acute mercury poisoning is diagnosed, administering compounds that bind to mercury and draw it out of the tissue — a process called chelation therapy — can remove elemental or inorganic mercury. However, chelation cannot remove methylmercury. Mercury has a strong affinity for the brain, especially the fetal brain. Methylmercury has been shown to alter the construction of structural components of the brain called microtubules and influence the development of neurons.
  • SOURCES OF MERCURY RELEASE- During the last 150 years, human activities may have doubled or tripled natural amounts of mercury in the atmosphere. Although there are many natural sources of mercury emissions — such as volcanoes, geothermal springs, geologic deposits, and the ocean — there are also numerous industrial sources such as coal combustion, waste incineration, and mining. The greatest contributors are coal-fired utilities and industrial boilers, which account for about 50 percent of the transmission of inorganic mercury to the atmosphere.

The Poisonous Effects of Mercury

Our Preferred Poison

A  little mercury  is  all that  humans  need to do away  with themselves quietly, slowly, and surely.

By Karen Wright  –  DISCOVER  Vol. 26  No. 03  –  March 2005                    Biology & Medicine

 

Let’s start with a straightforward fact:

Mercury is unimaginably toxic and dangerous.

A single drop on a human hand can be irreversibly fatal.

A single drop in a large lake can make all the fish in it unsafe to eat.

Often referred to as quicksilver, mercury is the only common metal that is liquid at room temperature. Alchemists, including the young Sir Isaac newton, believed it was the source of gold. In the modern era, it became a common ingredient of paints, diuretics, pesticides, batteries, fluorescent light bulbs, skin creams, antifungal agents, vaccines for children, and of course, thermometers. There is probably some in your mouth right now: So-called silver dental fillings are half mercury.

Mercury is also a by-product of many industrial processes. In the United States coal-fired power plants alone pump about 50 tons of it into the air each year. That mercury rains out of the sky into oceans, lakes, rivers, and streams, where it becomes concentrated in the flesh of fish, shellfish, seals, and whales. Last year the Food and Drug Administration determined there is so much mercury in the sea that women of childbearing age should severely limit their consumption of larger ocean fish. The warning comes too late for many mothers. A nationwide survey by the Centers for Disease Control shows that one in 12 women of childbearing age already have unsafe blood levels of mercury and that as many as 600,000 babies in the United States could be at risk. But that begs a critical question: At risk for what?

Infants born to mothers contaminated by mercury in Japan’s Minamata Bay in 1956 had profound neurological disabilities including deafness, blindness, mental retardation, and cerebral palsy. In adults mercury can cause numbness, stumbling, dementia, and death. “It’s no secret that mercury exposure is highly toxic,” says toxicologist Alan Stern, a contributor to a 2000 National Research Council report on mercury toxicity. But high-level exposures like those at Minamata cannot help scientists determine whether six silver fillings and a weekly tuna-salad sandwich will poison you or an unborn child. “The question is, what are the effects at low levels of exposure?” he says.

Data now suggest effects might occur at levels lower than anyone suspected. Some studies show that children who were exposed to tiny amounts of mercury in utero have slower reflexes, language deficits, and shortened attention spans. In adults, recent studies show a possible link between heart disease and mercury ingested from eating fish. Other groups claim mercury exposure is responsible for Parkinson’s disease, multiple sclerosis, Alzheimer’s, and the escalating rate of autism.

How–and in what form–mercury inflicts damage is still unclear. Yet scientists and policymakers agree that more regulation is imperative. The Environmental Protection Agency plans to finalize its controversial first rule on reducing mercury emissions from power plants this month, and delegates from the United Nations Environment Programme met in late February to discuss an international convention limiting mercury use and emissions.

A decade ago researchers and lawmakers agreed that lead, another heavy metal, was harmful to children at levels one-sixth as high as previously recognized. But it took scientists decades to establish the scope and subtlety of lead poisoning. Mercury is now a ubiquitous contaminant. The average American may have several micrograms of it in each liter of blood, and the atmospheric burden of mercury has perhaps tripled since the industrial age. Whatever needs to be done to protect humanity from its love affair with quicksilver, it had better happen soon.

In August 1996 Karen Wetterhahn, a chemistry professor at Dartmouth College in Hanover, New Hampshire, spilled a few drops of a laboratory compound called dimethyl mercury onto one of her hands. She was wearing latex lab gloves, so she didn’t think much of it. A colleague saw her at a conference the following November. “She said she thought she was coming down with the flu,” says toxicologist Vas Aposhian of the University of Arizona. By the time Wetterhahn was diagnosed with mercury poisoning, in January, it was too late. Despite subsequent treatment that helped clear the metal from her body, she lapsed into a vegetative state in February and died the following June.

Scientists are at a loss to explain why mercury often takes months to exert its effects. “If we knew that, we’d know a lot more about how mercury poisons the brain,” says Tom Clarkson, a toxicologist at the University of Rochester Medical Center.

The degree of mercury’s toxicity depends on the form and route of exposure. You can swallow the liquid form of elemental mercury without much fear because it doesn’t easily penetrate the lining of the stomach and intestines. On the other hand, liquid mercury vaporizes at room temperature, and when you inhale the vapor it moves right from the lungs to the bloodstream to the brain. A broken thermometer can release enough mercury vapor to poison the air in a room–one reason why some cities and several states discourage the sale of mercury fever thermometers.

Mercury also binds with other elements in salts and organic compounds of varying toxicity. Dimethyl mercury, the substance that poisoned the Dartmouth chemist, is a synthetic form of organic mercury rarely found outside a lab. A simpler organic compound called methylmercury is of greater concern because methyl-mercury is the form found in the flesh of fish.

Seafood is one of the two most common sources of mercury exposure in adults. Although concentrations of mercury in air and water are increasing, they are still too small for alarm. But bacteria process the mercury in lakes and oceans into a form that accumulates in living tissue. Plankton take in the bacteria and are in turn eaten by small fish. With each meal, the mercury concentration rises. Then larger fish eat the small fish, increasing tissue concentrations still more. Fish at the top of the food chain accumulate the most mercury. The species singled out by the recent FDA advisory–big predators such as albacore tuna, shark, and swordfish–can have 100 times more mercury in their tissues than smaller fish do.

The methylmercury in fish passes readily from the human gut to the bloodstream and on into all organs and tissues. It seems to act most powerfully on the brain because the compound is strongly attracted to fatty molecules called lipids, and the brain has the highest lipid content of any organ. Methylmercury crosses the protective blood-brain barrier by binding with an essential amino acid that has dedicated carrier proteins for shunting it into brain cells. Once inside brain cells, some of it gets converted to an inorganic form that sticks to and disable many structural proteins and enzymes essential to cell function. “It can destroy the biological function of any protein it binds to,” says Boyd Haley, a biochemist at the University of Kentucky.

Researchers learned how much  mercury the body can tolerate from studies of victims of catastrophic poisoning, such as the Japanese sickened by eating fish from Minamata Bay and the Iraqis who ate grain treated with a methylmercury-based preservative in the early 1970s. But those studies do not reveal how little mercury it takes to cause harm. At the time of her diagnosis, the Dartmouth chemist had 4,000 micrograms of mercury per liter in her blood. A diet consistently high in fish can create a blood-mercury level of about 25 micrograms per liter. That’s far below a lethal dose, but it still may not be safe.

Concerns about low-level toxicity haunt discussions of another ubiquitous source of mercury exposure: silver dental fillings. Elemental mercury, which makes up half of silver fillings, release mercury vapor, just as liquid mercury does. The vapor from dental amalgams is the primary source of the one to eight micrograms of mercury per liter of blood, that is, according to some sources, in the average American adult. That amount uncomfortably overlaps the Environmental Protection Agency’s current safe level of 5.8 micrograms per liter. But the EPA’s safety level is based on methylmercury exposure, about which more is known. No human studies have assessed prolonged exposure to low levels of mercury vapor. One study hints at subtle neural and behavioral anomalies in dentists, who collectively use 300 metric tons of mercury in amalgams each year and who often have two to five times the typical concentration of mercury in their urine.

“I think the methylmercury in fish is probably our least toxic exposure,” says Haley, who broadcasts the hazards of dental fillings.

Silver-mercury fillings have never been tested for safety. “The amalgam question will never be solved until we do a clinical trial like those we do with other medical devices,” says Aposhian.

“It’s really unclear what’s going on with dental amalgams,” says Stern, who notes that the issue is complicated by the potential for panic and lawsuits. “It’s a snake pit.”

One of the lessons of Minamata is that mercury, like lead, is harder on fetuses than on the women carrying them, or adults in general. In the Japanese event, women with no overt symptoms of poisoning gave birth to severely disabled children. “It was evident there was a major difference in susceptibility between the developing brain and the mature brain,” says Philippe Grandjean, an epidemiologist at the Harvard University School of Public Health. “When we saw serious poisonings in Minamata, that made us wonder whether mercury could be like lead.”

Studies of lead have shown that IQ decreases approximately two or three points for every doubling of prenatal and early postnatal exposure. To see if mercury has comparable effects, Grandjean, along with Pal Weihe at the University of Southern Denmark, is conducting the largest study to date of children’s cognition and behavior in a population routinely exposed to low levels of mercury. His work in the Faeroe Islands of Denmark includes 1,000 mother-child pairs and spans almost 20 years. In a typical year, Faeroe islanders consume 1,000 pilot whales, or one whale for every 50 islanders. “They belong to one of the most fish-eating populations in the world,” says Grandjean.

Whale meat is one of the most highly contaminated seafoods because whales are at the top of the food chain. Even so, the mercury content of whale meat is considerably lower than that of the hypertoxic Minamata fish. An earlier study of shark eaters in New Zealand suggested that relatively high levels of mercury in a mother’s hair during pregnancy correlated with a loss of three IQ points in her child. High levels, in that study, were identified as six parts per million and above in the hair shaft.

Grandjean gave a battery of sophisticated cognitive and developmental tests to the Faeroese children when they were 7 and 14. His results indicate that IQ drops 1.5 points for every doubling in prenatal exposure to mercury. The 2000 National Research Council report concluded that the risk documented by Grandjean “is likely to be sufficient to result in an increase in the number of children who have to struggle to keep up in school.”

“We learned there is a response at low levels,” says Grandjean. “It’s not a huge loss, but it’s certainly not negligible.”

Yet in another large, long-term epidemiological study conducted on the Seychelles Islands in the Indian Ocean, Clarkson has so far found no effect on neurological development from prenatal exposure to low levels of mercury in seafood. “We can’t exclude effects from 20 parts per million or even 12 parts per million,” he notes. But he concludes there is no graded risk that extends to the lowest exposure levels.

The 2000 research council report evaluated the Faeroe, Seychelles, and New Zealand studies and recommended that the EPA set safety standards based on Grandjean’s more sobering findings. The agency did. Then, for good measure, it added a 10-fold uncertainty factor–a safety margin to protect against scientific unknowns and individual differences in response to a toxin. The uncertainty factor lowers the threshold to a figure of 5.8 micrograms per liter of blood and 1.2 parts per million in hair.

The problem with safety factors is that they create a toxicological limbo between demonstrably harmful doses and levels that have been declared safe. Thus, when Centers for Disease Control surveys find that one in twelve American women of childbearing age–8 percent–have blood mercury levels above the safety threshold, the implications aren’t clear, either for them or for the children they bear. Epidemiologist Tom Sinks says, “It doesn’t tell us there’s a hazard.”

“The whole idea of a safety factor is to protect people,” Clarkson says. “You can’t turn it around to use an indication of who’s at risk. If you’re just above it, you aren’t necessarily in trouble.”

That kind of hedging, along with disagreement among population studies, leaves regulators with plenty of wiggle room. The FDA, for example, uses a more relaxed safety standard for mercury based on studies from the 1970s and 1980s. Where the EPA safety level for daily exposure is 0.1 microgram per kilogram (about 2.2 pounds) of body weight, the FDA’s standard is about 0.4 microgram per kilogram per day. The difference is four times as much mercury.

Concern about early exposure to mercury doesn’t end at birth. Until recently, many infants received regular injections of mercury on a state-mandated, medically sanctioned schedule. The mercury came from a compound called thimerosal that has been used as a preservative in vaccines and other medicines since the 1930s. In 1999 the FDA recommended that thimerosal no longer be used in pediatric vaccines, and manufacturers have removed if from all but the influenza vaccine. But some scientists and many more aggrieved parents are convinced that thimerosal in childhood vaccines has already caused, or at least catalyzed, the U.S. epidemic of autism.

An estimated 400,000 Americans today have autism, a once rare neurological disorder characterized by social withdrawal, difficulty communicating, and involuntary, repetitive movements. Although the exact numbers are in dispute, the rate of diagnosis seems to have climbed sharply in the last decade. In California the incidence of autism was six times higher in 2002 than 1987.

During that period, federal health officials added four new kinds of vaccines to the childhood immunization schedule, and the amount of mercury routinely administered to infants in the first six months of life more than doubled. Throughout the 1990s, a 3-month-old baby might receive as much as 63 micrograms of mercury in a single visit to a doctor–roughly 100 times the daily EPA safety level. By the age of 6 months, properly immunized children were exposed to at least 188 micrograms of mercury in a series of at least nine injections. Although the 1999 FDA action minimized such exposure, some infant flu vaccines still contain 12.5 micrograms of mercury per dose–more than 10 times the daily EPA safety level for a 20-pound baby.

Circumstantial evidence also implicates mercury in autism. Some of the symptoms of autism and mercury poisoning are similar, and Haley has garnered evidence from hair samples that autistic children do not clear mercury from their bodies as efficiently as most kids do. They may have a genetic susceptibility that allows more mercury to accumulate in their tissues, he says. That could make them more vulnerable to mercury-laced vaccines and the continuous low-level exposure from their mothers’ dental fillings. “It is amazing to me that no one has taken the tissue of autistic children to see if there is excess mercury there,” Aposhian told a committee at the Institute of Medicine in Washington, D.C., last year. “That’s one thing that really has to be done.”

There are other sources of uncertainty. The form of mercury in thimerosal–an organic compound called ethyl mercury–is the least studied of all mercury’s incarnations. When scientists argue about its toxicity, they typically rely on data from methylmercury, which may not be an equivalent form of exposure. Experts even disagree about whether ethyl mercury can cross the blood-brain barrier. (It probably does.) “There are no good ways to measure ethyl mercury in tissue,” toxicologist Polly Sager of the National Institute of Allergy and Infectious Diseases told the Institute of Medicine committee.

The Institute of Medicine concluded last May that no claim could be made for a causal link between mercury-laced vaccines and autism, but several independent researchers had complained that their access to federal vaccine databases, which could provide evidence of a link, had been repeatedly blocked. A few scientists, including Haley and neuropharmacolgoist Richard Deth of Northeastern University in Boston, continue to study possible mechanisms for the connection. Deth reported last year, for example, that in human nerve cells thimerosal blocks a chemical reaction called methylation that is critical to gene activity and that is also disabled by exposure to lead.

The report that first triggered worries about a connection between vaccines and autism was published in the British medical journal The Lancet in 1998. It described eight children whose behavioral problems surfaced within two weeks of receiving the measles-mumps-rubella vaccine. The Lancet and most of the article’s coauthors ultimately disowned the study because its lead author had not divulged that he was also being paid to conduct research for parents seeking to sue vaccine manufacturers. Nonetheless, the number of parents in the United Kingdom willing to immunize their babies with the vaccine dropped from 90 percent in 1998 to less than 80 percent in 2004.

Health officials in the United States addressed suspicions about immunization by recommending that thimerosal be removed from pediatric vaccines. Thimerosal might yet prove harmless, they reasoned, but the threat to public health posed by a drop in immunization rates was not worth risking. The same balance of risks exists regarding the issue of mercury in fish. The current Federal Dietary Guidelines Advisory Committee Report recommends at least two fish meals a week. Fish are high in omega-3 fatty acids, which have proven benefits in preventing heart disease, the number one killer in the United States. “We know mercury is a hazardous substance,” says the CDC’s Sinks. “We know that less is better than more. We know that fish and shellfish are the principal source of methylmercury. But we also know that fish and shellfish are pretty nutritious food: high in protein, high in vitamins. They contain healthy fats.”

But troubling evidence suggests that methylmercury in fish might cause heart disease. A seven-year study of more than 1,800 men in Finland showed that those who ate the most fish doubled their risk of heart attack compared with those whose diets had less fish. The same men showed the same increase in risk for death from coronary and cardiovascular disease. And Grandjean’s Faeroe Islands study found that prenatal exposure to mercury caused significant increases in blood pressure among 7-year-olds.

The most troubling aspect of this controversial heart-disease data is that deleterious effects occur at mercury-exposure levels equal to or lower than for any other toxicological outcome, including the subtle neurological symptoms in the Faeroe Islands study. In Grandjean’s most recent examination of 14-year-olds, he has found a doubling of certain neurotoxic effects at five parts per million in hair samples. In the Finnish study, the men with the doubled risk of heart attack had hair samples with only two parts per million of mercury. They were eating little more than an ounce of fish a day. Stern speculates that 10 percent of American mean may already eat enough fish to raise their risk of heart attack.

“There’s this interaction between mercury and fish oils that makes it very complicated because they both come from the same place,” he says.

The National Research Council report noted that low levels of mercury contamination might also harm the immune and reproductive systems. And mercury is being investigated in relation to Alzheimer’s, Parkinson’s, attention deficit disorder, and multiple sclerosis. But many low-level developmental effects will be difficult to identify, Stern says, because the compromised organ or function still falls within the range of normal. The intelligence scores of the Faeroese children, for example, were not pathologically low; it took rigorous statistical analyses to prove they were simply lower than they would have been otherwise. Likewise heart disease, as the nation’s leading killer, has plenty of confounding variables. “You’re looking to pull a signal out of a lot of noise,” Stern says.

That signal might soon get a lot stronger. While mercury contamination is no longer a threat in most childhood vaccines, it is likely to get worse in fish. “Because of the beneficial effects of fish consumption, the long-term goal needs to be a reduction in the concentrations of [methylmercury] in fish rather than a replacement of fish in the diet by other foods,” said the council’s report.

That goal is nothing less than unrealistic.

Mercury was a naturally occurring element in Earth’s atmosphere long before coal-fired generators, medical-waste incinerators, and chlor-alkali plants put more there. Some mercury escapes into the air when volcanoes erupt and mountains erode. It stands to reason that mercury has been accumulating in the flesh of fish, shellfish, and marine mammals since humankind began eating them–which is most likely why humans have a protein called metallothione to help detoxify mercury and other heavy metals.

But human activities have caused the mercury content of the atmosphere to rise by 1.5 percent a year, according to the U.S. Geological Survey, and the problem is global. Roughly half of the mercury deposited on U.S. soils and streams comes across the Pacific from Asia. Last year a United Nations report found that the toxin can travel thousands of miles in the atmosphere to contaminate pristine and uninhabited areas, such as the Arctic. Still, the United States has so far balked at attempts by the United Nations Environment Programme to draw up a binding protocol to reduce mercury pollution worldwide.

In the 1990s the United States made considerable progress in curbing emissions from incinerators for medical and municipal waste. Yet the number of states issuing local fishing advisories went from 27 to 48 in the last decade. Due to heightened concern, advisories for mercury are increasing faster than for any other pollutant.

The EPA is in the final stages of formalizing a rule that would limit emissions from coal-fired utilities, which produce 42 percent of the nation’s domestic mercury pollution. The agency’s standing proposal has been for a 70 percent reduction in mercury emissions by 2018. But environmentalists argue that the Clean Air Act calls for a 90 percent reduction by 2008. In 1992 the Natural Resources Defense Council sued the EPA for not maintaining the act’s standards, and in 1994 the parties reached a settlement. Under the terms of the agreement, the agency is required to issue a cleanup rule this month.

 

Editorial About Mercury

Rising Mercury

Home Editorials – from the Bangor Daily News — Thursday, Apr. 12, 2001

Despite protests from the American Dental Association, any country that seriously discusses doing away with mercury thermometers because of their potential impact on health cannot be long from restricting the use of mercury dental fillings.

Congress will soon work on the question while Maine reviews LD 1409, a concept bill that seeks to examine the long-term effects of these fillings and the steps the state should take to protect residents and the environment. For one expert who testified last week, the answers are clear. Dr. Boyd Haley, chairman of the Department of Chemistry at the University of Kentucky, concludes that normal body loads of mercury in older adults produce two diagnostic hallmarks for Alzheimer’s disease.

Further, he says, in a test for mercury in the blood and urine of more than 1,000 soldiers, the vast majority, more than 87 percent, was traced to dental amalgams. Further still, the primary source of mercury in wastewater treatment plants came through feces and urine of people with these fillings. That is, he and other reputable scientists are identifying dental amalgams as a major source of this toxin in humans and in the environment.

The ADA will have none of this. It says 150 years of dentistry show that the amalgams are not a problem, as evidenced by the dentists themselves who spend a career around these products. Individual dentists in Maine, however, sometimes tell a different story. They note that the alternatives to the mercury amalgams are more expensive but that they are safer for their patients, themselves and their staff, and for the environment.

The legislature’s job in this case is not to start an argument among dentists but to look at the relative risk of mercury to the public and the level of importance of dental amalgams in contributing to that risk. Mercury can be toxic to the nervous system. U.S. dentists, according to the U.S. Geological Survey, annually use a total of between 40 and 60 metric tons of mercury in their practices but other sources have attracted the attention of regulators.

Bills in Congress would more tightly regulate mercury emissions from power plants and incinerators, would reduce mercury in light bulbs and eliminate it in thermometers, switches and other household products. Rep. Tom Allen, who has followed the mercury issue closely, will reintroduce a mercury-reduction bill after the congressional break that for the first time encourages states, communities, dentists and dental associations to work toward eliminating the mercury filling.

The potential for environmental damage alone would make mercury from dental offices endangered. A fair review of the studies of its human health effects by the Bureau of Health would take only several months. If the work by the bureau turns out as scientists like Dr. Haley suspect it will, lawmakers should begin a reduction and phase-out of this type of dental fillings.
