Polytetrafluorieteeni (IUPACin lyhenne PTFE) on polymeeri, jossa hiiliketjuun on liittynyt fluoriatomeja.Sitä kutsutaan usein kauppanimellä Teflon. Teflon oli alun perin DuPont-yhtiön kauppanimi vuonna 1938 patentoimalleen polytetrafluorieteenille.Polytetrafluorieteenin muita kauppanimiä ovat Fluon ja Hostaflon.

From Wikipedia, the free encyclopedia Perfluorooctanesulfonamide (PFOSA) is a synthetic organofluorine compound. It is a fluorocarbon derivative and a perfluorinated compound, having an eight-carbon chain and a terminal sulfonamide functional group.

Perfluorooctanesulfonic acid (PFOS) is a man-made global pollutant. PFOS is suspected of compromising the immune system of wildlife and a small segment of highly exposed people globally. This is the common definition for perfluorooctanesulfonic acid, other definitions can be … PFOSA, a persistent organic pollutant, was an ingredient in 3M 's former Scotchgard formulation from 1956 until 2003, and the compound was used to repel grease and water in food packaging along with other consumer applications. It breaks down to form perfluorooctane sulfonate (PFOS). Perfluoroctansulfonsäure (Anion Perfluoroctansulfonat oder kurz PFOS) ist eine chemische Verbindung aus der Gruppe der per- und polyfluorierte Alkylverbindungen (PFAS). Üblicherweise wird bzw.

perfluorooctanoic acid (PFOA), which is among the perfluorinated carboxylic acids (PFAA)s From Wikipedia, the free encyclopedia Perfluorooctanesulfonamide (PFOSA) is a synthetic organofluorine compound. It is a fluorocarbon derivative and a perfluorinated compound, having an eight-carbon chain and a terminal sulfonamide functional group. PFOS has been found in very small amounts in the blood of people and animals worldwide. PFOS is extremely persistent. If PFOS is released to the environment it will not be broken down in air. It can travel long distances in the air on particles that eventually fall to the ground. It is not expected to be broken down by sunlight.

It is not expected to be broken down by sunlight. PFOA and perfluorooctanesulfonic acid (PFOS) have been estimated to be in every American person’s blood stream in the parts per billion range, though those concentrations have decreased by 70% for PFOA and 84% for PFOS between 1999 and 2014, which coincides with the end of the production and phase out of PFOA and PFOS in the US. PFOS is used in many industrial applications including; fire fighting foams, pesticides and consumer applications like surface coatings for carpets, furniture and paper. PFOS is a persistent compound, shows little biodegradation and is globally distributed in living organisms.

This is the common definition for perfluorooctanesulfonic acid, other definitions can be discussed in the article. Fluorosurfactants such as perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), and perfluorononanoic acid (PFNA) have caught the attention of regulatory agencies because of their persistence, toxicity, and widespread occurrence in the blood of general populations and wildlife. PAPS, a type of paper fluorotelomer coating, and PFOA precursor, is also used in food contact papers. Despite DuPont's asserting that "cookware coated with DuPont Teflon non-stick coatings does not contain PFOA", residual PFOA was also detected in finished PTFE products including PTFE cookware (4–75 parts per billion).
