Sommaire:The effects of fluoride on the body were investigated. Topically applied fluoride of varying concentrations on eggshells and bovine teeth showed discoloration, weakness, and minimal differences between fluoridated and controlled variables in acid application. This indicates little fluoride protection. When tested on Daphnia magna, fluoride produced an LC50 of 0.0035%.
