Fluorosilicic acid is not fluoride, it is something very different, and it strikes me as downright bizarre that it is perfectly legal to dump this toxic waste product into the rivers and streams of America as long as it passes through the bodies of human beings first. In other words, it's illegal to take a bucket of fluorosilicic acid and dump it into a stream, but it is perfectly legal to dump it into the bodies of human beings, whose waste products will subsequently enter those same streams and rivers.
