Toxicol Sci. 2002 ; 68(1) : 249-264. Thomford PJ - 4-week capsule toxicity study with perfluorooctane sulfonic acid potassium salt (PFOS ;

Perfluorooctane sulfonate (PFOS) and its salts are perfluorinated organic compounds with surfactant properties. Common salts of PFOS include the ammonium, diethanolamine, potassium, and lithium forms. PFOS can be released from several fluorochemicals, such as perfluorooctane sulfonamide

On May 9, 2009, the Conference of the Parties 4 of the Stockholm Convention (COP-4) in Geneva placed perfluorooctane sulfonate and perfluorooctane sulfonyl fluoride (PFOS and PFOSF) in Annex B (see below for other included substances). Perfluorooctane sulfonate (PFOS, potassium salt) was purchased from Fluka Chemical (Steinheim, Switzerland). The chemical was reported to be 91% pure by the supplier. Our analysis indicated that approximately 71% of the chemical was straight-chain, and the remaining 29% was branched. 3M Company (2001a) Screening studies on the aqueous photolytic degradation of potassium perfluorooctane sulfonate (PFOS).
