“Fluoridation chemicals are often a by-product, never an industrial waste”
The most common fluoride chemical used is hexafluorosilicic acid, with the compound formula H2SiF6, which can be obtained from other industrial processes. One can hardly call it a waste product if it is of commercial value and so a more correct name would be a by-product (please read on prior to concluding that the commercial value is based on “spin”). Waste also is used because it people generally think of waste as dirty, however this is a refined chemical, not a loaf of bread or chunk of ham left out in the sun.
For instance, sodium chloride, or table salt, can be refined from the ocean, a dry salt lake or even urine. Regardless where one extracts it, it remains sodium chloride. The same is true of hexafluorosilicic acid.
Have you heard of any other anti-fluoridation arguments that I’ve not covered? Feel free to forward them to me via the post submissions forms here and, time pending, I’ll do what I can to provide a strong counter-argument based upon facts.
