Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that include Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA). These elements have a negative effect on the health of those exposed to them. Used as early as the 1940s, PFAS were once thought of as beneficial because of their ability to repel

Historically the major uses for PFOS were in providing grease, oil and water resistance to materials such as textiles, carpets, paper and in general coatings but At COP-4 in 2009, the Conference of the Parties decided to list perfluorooctane sulfonic acid (PFOS), its salts and perfluorooctane sulfonyl fluoride (PFOSF) in Annex B to the Stockholm Convention (decision SC-4/17).The risk profile, risk management evaluation and addendum to the risk management evaluation adopted by the POPs Review Committee are available below: PFOS was widely used in the past in products to provide protective coatings to materials such as textiles and leather. It was also used in some fire fighting foams.
