Hydrofluorosilicic acid is recovered from the smokestack scrubbers during
the production of phosphate fertilizer and sold to most of the major
cities in North America, which use this industrial grade source of
fluoride to fluoridate drinking water, rather than the more expensive
pharmaceutical grade sodium fluoride salt. Fluorosilicates have never been tested for safety in humans. It is just the best way of disposing of a very toxic by-product: SELL it for human consumption. Dont you just love the empathy and compassion of these fertilizer and paint corporations.

The toxicity of this form of fluoride is today NO LONGER IN QUESTION thanks to a massive and official survey of the Republic of Ireland general health outcome when compared to Northern Ireland. See here https://www.in-syncminerals.com/reference-material–links.html
