Fluoride in Drinking Water, Diet, and Urine in Relation to Bone Mineral Density and Fracture Incidence in Postmenopausal Women.

April 6, 2021 | Environmental Health Perspectives | Helte E, Donat Vargas C, Kippler M, Wolk A, Michaëlsson K, Åkesson A. | 129(4):47005
Exposure to fluoride occurs mainly through drinking water, which may include fluoride from natural sources and fluoride added to prevent tooth decay. Naturally occurring fluoride concentrations can vary substantially, from insignificant to well above the World Health Organization (WHO)-recommended limit of 1.5mg/L (WHO 2006), whereas the concentration in artificially fluoridated water is typically around 0.7mg/L (U.S. Department of Health and Human Services Federal Panel on Community Water Fluor

Conclusions From the data of this study and the findings of other earlier studies, we can conclude that operating room personnel exposures to WAG are associated with changes in blood levels of IgG and IgM, total lymphocytes, CD4+ and CD8+ subtypes, and accordingly, in CD4:CD8 ratios. It is quite possible these changes would likely be associated with immune dysfunction in these WAG-exposed hosts. As it is not yet clear if this might be reflected as reduced host resistance and/or an increased r
