In the below letter to the editor of Neurotoxicity Research, Dr. Jean Harry, lead contact researcher for the 2017 McPherson, et al NTP study, responds to criticisms made by fluoridation opponents: July 5, 2018 Dear Dr. Kostrzewa I am writing in response to a letter...
Christopher A. McPherson, Guozhu Zhang, Richard Gilliam, Sukhdev S. Brar, Ralph Wilson, Amy Brix, Catherine Picut, G. Jean Harry First Online: 05 February 2018 Abstract At elevated levels, fluoride (F−) exposure has been associated with adverse human health effects....
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...
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...
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...
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...
