The decision followed the announcement by a major US manufacturer (3M) to globally phase out PFOS (perfluorooctanesulfonate) in serum is negatively associated with testosterone levels, but not with semen quality, in healthy men.

For PFOA, the majority of the aquatic ecotoxicity studies have been conducted with the ammonium salt (APFO) of the prefluorooctanoic acid. Under environmentally relevant conditions in aqueous environmental compartments, PFOA will exist as the fully ionized component (COO −). The surface active properties of the potassium salt of PFOS make a direct determination of the octanol-water partition coefficient impossible. In a preliminary study reported by 3M an inseparable emulsion was formed. 3M determined the solubility of PFOS (K salt) in octanol as 56 mg/L, and calculated the log Kow from the ratio of solubilities, giving a log Kow value of -1.08.

The stock solution of PFOA was prepared in deionized water (100 mg L −1 ), and the PFOS stock solution (20 mg mL −1 ) was prepared in dimethylformamide (DMF) and diluted 100 X in distilled water to achieve 200 mg L −1 . The table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Salts of perfluorooctanoic acid, in particular ammonium perfluorooctanoate (APFO), have been used as surfactants and processing aids in the production of fluoropolymers and fluoro-elastomers.

ammonium, diethanolamine, potassium, and lithium forms. PFOS can be released from several fluorochemicals, such as perfluorooctane sulfonamide (PFOSA), N-ethyl perfluorooctane sulfonamidoethanol (N-EtFOSE), and N-ethylperfluorooctane sulfonamide (N-EtFOSA) by transformation or degradation processes.
It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009. PFOS can be synthesized in industrial production or result from the degradation of precursors.
