Perfluoroalkyl Sulphonates (PFSA)

PFSAs are commonly used in commercial products because of their excellent stability properties. The high chemical and biological stability of PFSAs is conferred by their strong carbon-fluorine bonds. PFSAs, in particular, are now considered to be a group of contaminants that are widely used worldwide. 

The chemicals in this group are perfluoroalkyl sulfonic acids, perfluoroalkyl sulfonic fluoride, and salts of the perfluoroalkyl sulfonate (PFSA) anion, all of which contain perfluorinated carbons terminated with a sulfonate group and have the potential to hydrolyze and/or dissociate to form a series of environmentally persistent perfluorosulfonate anions.
