Response to journalist to the following claim by EPA: “The petition has not set forth a scientifically defensible basis to conclude that any persons have suffered neurotoxic harm as a result of exposure to fluoride in the U.S. through the purposeful addition of fluoridation chemicals to drinking water or otherwise from fluoride exposure in the U.S.”]
EPA’s own Guidelines on Neurotoxicity Risk Assessment highlight the importance of having a robust margin between the doses of a chemical that cause neurotoxic effects and the doses that humans receive. We presented the EPA with over 180 studies showing that fluoride causes neurotoxic harm (e.g. reduced IQ), and pointed out that many of these studies found harm at levels within the range, or precariously close to, the levels millions of U.S. children now receive. Typically, this would be a cause for major concern. But, unfortunately, the EPA has consistently shied away from applying the normal rules of risk assessment to fluoride — and it has unfortunately continued that tradition with its dismissal of the Petition.
