Inorganic fluorides are used in Canada and emitted into the Canadian environment both from anthropogenic (estimated releases of approximately 23 500 tonnes/year) and natural sources (amounts released are not known). The main anthropogenic sources of inorganic fluorides in Canada include phosphate fertilizer production, chemical production, and aluminum smelting. Gaseous inorganic fluorides (e.g., hydrogen fluoride and sulphur hexafluoride) are primarily released into the atmosphere, whereas particulate compounds (e.g., sodium fluoride and calcium fluoride) are released into the aquatic and terrestrial environments.
There is more than one CAS number that applies to this group of substances.
