Sure, Bryan

1.  There are no “SYNONYMS” for fluorosilic acid.  FSA, HFA, and HFSA are all the same compound.

2.  FSA is not a toxic waste product of anything.  It is a compound produced for specific purposes, fluoridation being but one.  “Waste”, by definition has no useful purpose.

3.  FSA is not, nor ever has been, “injected into the natural environment”.  It is produced for specific purposes.

4.  FSA is not an inorganic fluoride.  FSA is a compound.  Fluoride is the anion of the element fluorine.  An anion is a negatively charged atom.  An atom is not a compound.

5.  There is no substance known to man which is not toxic at improper levels, including plain water.  Fluoride is no different.  Chronic exposure to abnormally high levels of fluoride can, indeed, have adverse effects, often, severe ones.  This is the reason that the concentration of fluoride in fluoridated water is kept at a level far below the threshold of adverse effects.
