Fluoride Metabolism in Pregnant Women: A Narrative Review of the Literature.

(This article belongs to the Special Issue Fluoride Metabolism and the Effects of Fluoride on Metabolic Pathways and Diseases) Abstract Epidemiological studies use biomarkers of fluoride exposure in pregnant women as surrogate measures of fetal fluoride exposure; however, there is little understanding of how pregnancy affects fluoride metabolism and its biomarkers. This narrative review summarizes […]

Exposure to environmental neurotoxic substances and neurodevelopment in children from Latin America and the Caribbean.

Introduction Environmental neurotoxicants are pollutants that can negatively affect many cellular metabolic-processes through different pathways: neuroendocrine/thyroid hormone disruption (Pb, methyl-Hg, organochlorines, and polychlorinated biphenyls-PCB), oxidative stress (Pb, methyl-Hg, organochlorines, and chlorpyrifos), dopamine dysfunction (Pb, methyl-Hg, As, chlorpyrifos, pyrethroids, and organochlorines) (Heyer and Meredith, 2017; Rock and Patisaul, 2018). Pistollato et al. (2020) studied neurotoxic substances […]

Opinion: Serious failures in Wellington’s fluoride system

Note from Fluoride Action Network: This opinion piece was written by Peter Griffin, a science and technology writer. Griffin should have a lot of credibility as he is the founding director of the Science Media Centre and founding editor of Sciblogs.co.nz. In August 2019 Griffin wrote an opinion piece on the Green et al. paper […]
