Barium is a divalent cation and alkaline earth metal that can be found in naturally occurring mineral deposits. MDL number MFCD00003450. Perhaps the most widely known use of fluoride is its addition to public drinking water supplies at about one milligram per liter (mg/L) of a fluoride salt, measured as fluoride, for the purpose of reducing tooth decay. It is less resistant to water than calcium fluoride, but it is the most resistant of all the optical fluorides to high-energy radiation, though its far ultraviolet transmittance is lower than that of the other fluorides. Fluorine is a natural trace element and exists in almost all soils. It is one of the most common water-soluble salts of barium. The level of the S MCL was set based upon a balancing of the beneficial effects of protection from tooth decay and the undesirable effects of excessive exposures leading to discoloration.
