PFOS and PFOA have been extensively produced and studied in the United States. These manmade substances have been synthesized for water and lipid resistance. They have been used extensively in consumer products such as carpets, clothing, fabrics for furniture, paper packaging for food, and other materials (e.g., cookware) designed to be waterproof, stain-resistant or non-stick.

PFOS, together with PFOA, has also been used to make aqueous film forming foam (AFFF), a component of fire-fighting foams, and alcohol-type concentrate foams. PFOA and PFOS could also be dangerous to pregnant women. Some studies have linked the chemicals to fetal growth problems, including low birth weight. But the science is contested. In general, the effects of PFOA and PFOS are higher for the young and unborn. PFOS and PFOA can affect both groundwater and surface water supplies in areas where the contaminants have taken hold in an environment.

PFOS and PFOA are used to give grease, oil and water resistance to textiles and paper What is PFOS/PFOA. Perfluorooctane sulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA) belong to a family of manmade chemicals used for more than 50 Nov 8, 2019 The two PFAS chemicals you're most likely to hear about are perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). Neither of PFOA and PFOS are sometimes referenced in a group of similar chemicals called per- and polyfluoroalkyl substances (PFAS). Both PFOA and PFOS were Hazards and risk associated to Perfluorooctanoic acid (PFOA), its salts and list of PFOA-related substances, similar to the current EU restriction of PFOS. Army Polyfluoroalkyl Substances (PFAS) · The Army Addresses PFOS/PFOA · Map: Sampling Results with PFOS/PFOA Exceedances at Army Installations. PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonate) are the two most commonly produced PFAS worldwide (1).

PFOA and PFOS are unregulated drinking water contaminants addressed in the EPA’s Unregulated Contaminant Monitoring Rule (UCMR3). In May 2016, the EPA issued a health advisory regarding PFOA and PFOS in drinking water, reducing the health advisory level of these compounds from 400 parts per trillion (PPT) for PFOA and 200 PPT for PFOS to a combined level of 70 PPT.

Till de kortkedjiga PFAS hör PFHxA (perfluorhexansyra) och PFHxS (perfluorhexansulfonat) som båda består av 6 kol och hör till den så kallade C6-kemin. 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 Det är känt att PFOS/PFOA kan orsaka kronisk leverskada, höja risken för cancer och senare studier har visat på att ämnena i gruppen kan vara kopplade till övervikt.

Perfluorooctane sulphonate (PFOS) and Perfluorooctanoic acid (PFOA) are perfluorinated chemicals which historically have had a wide range of uses including polymer precursors, certain fire-fighting foams and providing grease, oil and water resistance to materials such as textiles,

There is no national legal cap on the amount of PFOA and PFOS in drinking water. Uppdaterade intagsberäkningar för PFOS och PFOA Livsmedelsverket har tagit fram uppdaterade data för intagsberäkningar för PFOS och PFOA, beräknat i nanogram (ng) per kilo kroppsvikt och dag.
