A Canadian Population-based Study of the Relationship between Fluoride Exposure and Indicators of Cognitive and Thyroid Functioning; Implications for Community Water Fluoridation
Abstract: Concerns exist regarding potential harms of community water fluoridation. The study objective was to examine the association between fluoride exposure and indicators of two health outcomes for which concerns have been expressed, cognitive and thyroid...
Can Fluoridation Affect Lead (II) In Potable Water? Hexafluorosilicate and Fluoride Equilibria In Aqueous Solution
Overall we conclude that no credible evidence exists to show that water fluoridation has any quantifiable effects on the solubility, bioavailability, bioaccumulation or reactivity of lead (0) or lead (II) compounds. The governing factots are the concentrations of a...
Blood Lead Concentrations in Children and Method of Water Fluoridation in the United States, 1988-1994
Our analysis does not offer support for the hypothesis that silicofluorides in community water systems increase PbB concentrations in children. On the other hand, given the limitations of our data, our analyses cannot refute a possible link between water fluoridation...
Chemistry and Bioavailability Aspects of Fluoride in Drinking Water
1. Hexafluorosilicate added to fluoridate water is effectively 100% dissociated to form fluoride ion under water treatment conditions. Therefore in terms of chemistry and bioavailability there is absolutely no difference between added and “natural” fluoride. 2. The...
