Includes information on 3M’s research of PFOA and PFOS … PFAS eller högfluorerade ämnen är ett samlingsnamn för en grupp organiska ämnen som alla består av en kolkedja där väteatomerna är helt eller delvis utbytta mot fluoratomer. Det är en stor och komplex grupp på mer än 4700 identifierade ämnen med varierande egenskaper och bred användning i samhället. Gemensamt för alla PFAS-ämnen är att de är mycket svåra att bryta ner och Perfluoroctaanzuur of decapentafluoroctaanzuur, vaak afgekort als C8 of PFOA (van het Engelse perfluorooctanoic acid) is een hulpstof in de bereiding van teflon.In zuivere toestand is het een kleurloze vaste stof..

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. Also, PFOS- and PFBS-induced increase in ER and AR expression highlights the need to further study effects of PFOS and PFBS on subsequent gonadal development, sexual dimorphism, and secondary sex characteristics in X. laevis.

According to OECD, there are at least 4730 different PFASs. Perfluorooctanoic acid (PFOA) (conjugate base perfluorooctanoate)—also known colloquially as C8—is a perfluorinated carboxylic acid produced and used worldwide as an industrial surfactant in chemical processes and as a material feedstock.

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 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 –.

The estimated bioconcentration factor in fish ranges from 1,000 to 4,000 (EFSA 2008; MDH 2017a). PFOA has been shown to bioaccumulate in air breathing species, including humans, but not in fish (Vierke and others 2012). Structure, properties, spectra, suppliers and links for: Perfluorooctanesulfonic acid, 1763-23-1. PFOS has a linear perfluoroalkyl carbon chain of 8 atoms and a sulfonic acid functional group (Danish EPA, 2013).

PFOS has a linear perfluoroalkyl carbon chain of 8 atoms and a sulfonic acid functional group (Danish EPA, 2013). Chemical name: Perfluorooctane sulfonate Molecular formula: C8F17SO3- By 2012, PFOS and PFOA were added to the Prohibition of Certain Toxic Substances Regulations. However, since these chemicals do not easily break down, their long-lasting effects are still a concern for homes, the environment and water supplies in North America today. Tahun 1999, EPA meminta semua perusahaan untuk mempelajari dampak bahan kimia yang diperfluorinasi setelah EPA menerima data distribusi dan toksisitas PFOS di seluruh dunia. Atas desakan EPA, pada Mei 2000, 3M mengumumkan berakhirnya pembuatan produk-produk berbahan PFOA, PFOS, dan PFOS yang selama ini menjadi produk terlaris 3M.
