RE;  X            IANG UPDATE:  Appeal to the Governor under RCW 34.05.330(3) to overturn the Board of Health’s Denial of Rule Change Petition for Health Education to Reduce Brain Damage and Lowering of IQ in Children.

REQUEST: Our request for public health education on public water billings to advise customers that the fluoride content in the water may decrease IQ would be at no cost to the state and if heeded by all water users would save the people and State of Washington a great deal of economic, societal and personal harm, especially to children.  It is within the Governor’s jurisdiction to reduce future economic damage to the citizens and government of Washington State by mandating that the public be educated about the risks associated with water fluoridation, especially in light of the following new study.

On December 17, 2010 the National Institute of Environmental Health Sciences, National Institutes of Health, U.S. Department of Health and Humans Services, Environmental Health Perspectives released a study (attached) by scientists at the Jiangsu Province and Sihong County Centers for Disease Control and Prevention and Fundan University entitled “Serum Fluoride Level and Children’s Intelligence Quotient in Two Villages in China” by Xiang et al.[1]

Xiang reported an IQ drop of 8 points when fasting serum fluoride concentration increased from 0.04 mg/L to 0.08 mg/L in children.  Clearly a serum level of 0.08 mg/L is not protective of the human brain.  People drinking fluoridated water (1 mg/L, 1 ppm) have a mean serum fluoride level of 0.21 mg/L,[2] which is 263% higher than 0.08 mg/L a level known to be hazardous to the brain.   And further, the Xiang study did NOT demonstrate that a fluoride serum concentration of the control village at 0.04 mg/L is safe and without risk. Xian reported, “there is no cut-off point of serum fluoride which is considered acceptable by WHO or other academic organizations.”

Our previous appeal to the Governor used an estimated 5 IQ point drop resulting in a $20 billion annual negative economic impact in Washington State and appears to be too conservative by perhaps half.

Neither CDC, EPA, FDA, WDOH, WBOH, nor any dental association evaluates the economic impact of fluoridation.  The Governor has jurisdiction over the economic harm to the state and its citizens.  At over $55 million in economic harm per day in Washington State, directly and indirectly from brain damage alone, the Governor should estimate the costs to the state and overrule the Board of Health’s denial for public health education. There is no sane reason for preventing the public from gaining health education to protect the developing brains of their children.  Education should be a cornerstone of Governments.

Blindly following the American and Washington Dental Associations is a seriously flawed methodology.  These Associations have no duty to protect the public from harm or economic damage—they represent dentists, not the public, and there is a world of difference.  Emergency action by the Governor is critical.  Dental decay will not increase with a cessation of fluoridation nor with the beginning of health education in statements on water bills mailed to the public. Education will create neither cost nor hardship to the state and water districts.

REQUEST: Based on the scientific evidence available, we are requesting a meeting with the Governor or Governor’s representative as soon as possible.

Xiang provides the following graph comparing the drop in IQ between the two villages at 0.04 mg/L and 0.08 mg/L.

Xiang’s study is more consistent with the comparison of rates of fluoridation of states in the USA finding a tripling of mental retardation in the highest fluoridated states compared to the least fluoridated states.  However, even the least fluoridated states do not take into account the excess fluoride some are ingesting from fluoride supplements, toothpaste, dental and medical products, pesticides and post-harvest fumigants.  Achieving a serum fluoride level of 0.04 mg/L or less for everyone, will require a massive reduction of fluoride exposure from all sources.  Our request to the Governor for health education is critical to protect the children of Washington.


Recommendations for “optimal” fluoride intake have been 3 mg/day for women and 4 mg/day for men,[3] several times more (probably 10 fold or more) than the possible level of safety for all, 0.04 mg/L fluoride serum level.  Fluoride is more toxic than lead and no amount of lead is considered “safe.”

NRC 2006 Figure 2-6 (Left) ” serum . . .  fluoride concentrations as functions of fluoride concentration in drinking water.[4]

Xian’s graph below shows a clear relationship between the increased fluoride exposure and serum fluoride levels.

The negative economic impact from fluoridation is greater than the impact from tobacco smoking, but unlike smokers, children are forced to consume fluoride.

Thank you for your prompt action to protect the children of Washington.

[2] The NRC 2006 report, page 57 (page 70 in online version), Table 2-16, references Bachinskii’s work finding a 0.21 (0.01) mg/L serum fluoride level with 1 mg/L fluoride in drinking water.  If you do not have a copy of the NRC 2006 report, we will provide you a copy.

[3] (1999, 2000). Burt (1992) attempted to track down the origin of the estimate of 0.05-0.07 mg/kg/day as an optimum intake of fluoride but was unable to find it. He interpreted the available evidence as suggesting that 0.05-0.07 mg/kg/day (from all sources) “remains a useful upper limit for fluoride intake in children” (see also NRC 1993). (2006 NRC Report p. 68.)
