[3] To perfluor alkylforbindelser er i 2009 føjet til Stockholm-konventionens liste over persisterende organiske miljøgifte . PFAS are a large, complex, and ever-expanding group of manufactured chemicals that are widely used to make various types of everyday products. For example, they keep food from sticking to cookware, make clothes and carpets resistant to stains, and create firefighting foam that is more effective. PFAS are used in industries such as aerospace, automotive, construction, electronics, and military. PFOS:n ja sen johdannaisten käyttörajoituksia astui voimaan 2000-luvun alussa. PFOA:n rajoitukset astuivat voimaan vuonna 2020.

De generella För PFCA finns i jämförelse med PFOS (perfluoroktansulfonat) relativt lite kunskap om hälso- och miljöeffekter. Undantaget är PFOA, som genom åren fått allt Till de långkedjiga PFAS-ämnen hör PFOA (perfluoroktansyra) och PFOS (perfluoroktansulfonat), som båda består av 8 kol och hör till den så kallade C8-kemin. av S Johansson · Citerat av 4 — brandsläckningsskum och vattenkanoner (Wikipedia, 2009c). På grund av de perfluorerade ämnen, främst PFOS, som finns i brandskum har övningarna med PFAS i maten. PFAS som släpps ut i miljön hamnar till slut i maten, eftersom de i princip inte kan brytas ner.

Het belangrijkste gebruik van de stof is voor de productie van fluorhoudende polymeren zoals polytetrafluorethyleen (PTFE, beter Bilden visar PFOA, ett exempel på PFCA, med en fullständigt fluorerad kolkedja som binder till en karboxylgrupp. Perfluornonansyra (PFNA) Perfluorkarboxylsyror ( PFCA) är perfluorerade karboxylsyror.

PFOS and PFOA have been detected in a number of U.S. cities in surface water and sediments downstream of former fluorochemical production facilities and in wastewater treatment plant . effluent, sewage sludge and landfill leachate (EPA . 2002b; OECD 2002). 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. PFOS was the predominant analyte present in the pools and all three analytes showed statistically significant increasing trends from 1972 to 2000, with concentrations reaching a plateau in the 1990s.

Halten PFOA är väldigt låg (ca 100ppb, parts per billion). Denna form av impregnering är väldigt hållfast. God; PFOS - Perfluoroktansulfonsyra och dess derivater Färgrepresentation av klassning Ej klassad; Polyaromatiska kolväten (PAH) Färgrepresentation av Perfluorooctanesulfonic acid (PFOS) (conjugate base perfluorooctanesulfonate) is an anthropogenic fluorosurfactant and global pollutant. PFOS was the key ingredient in Scotchgard, a fabric protector made by 3M, and numerous stain repellents. It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009. 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. Per- and polyfluoroalkyl substances (PFASs, also perfluorinated alkylated substances) are synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain. As such, they contain at least one perfluoroalkyl moiety, –C n F 2n –.
