PFOS EQS dossier 2011 2 Molecular weight (g.mol-1) 500 (acid), 538 (potassium salt) (Environment Agency, 2004) PFOS is the perfluorooctane sulphonate anion and is not a substance as such and therefore does not have a specific CAS number. It is commercially available in the form of salts, derivatives (PFOS-substances) and polymers (PFOS-polymers).

È stato usato soprattutto per materiali come tessuti, tappeti e carta al fine di renderli resistenti a grasso, olio e acqua. Inoltre, è stato ed è ancora utilizzato in modo limitato in galvanostegia , in fotografia, fotolitografia , nell'industria dei semiconduttori , in schiume antincendio e in fluidi idraulici per l 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. Hittills är dock relativt lite känt rörande effekterna av de nivåer som mätts upp i människors blod. PFOS (perfluoroktansulfonat) är ett ämne som kan bilda vatten-, fett- och smutsavvisande ytor.

21 Feb 2018 What Are PFOA and PFOs? PFO is perfluorooctane sulfonate and PFOA is perfluorooctanoic acid and both are part of a class of compounds 

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 has been in commercial use since the 1950's, predominantly in soil and stain-resistant coating products on fabrics, carpets, and leather, and in grease and oil resistant coatings on paper products, including food contact papers.

PFOS og PFOA skader ikke arvestoffet DNA direkte, og ut fra strukturlikhet forventes ikke andre PFAS-er å skade DNA. PFOS og PFOA er kreftfremkallende i lever i forsøksdyr. Det er for lite informasjon til å konkludere om PFAS er kreftfremkallende hos mennesker.

Il existe de nombreuses autres substances chimiques apparentées au SPFO et précurseurs de  What does PFOS and PFOA stand for? PFOS refers to Perfluorooctane Sulfonate and PFOA stands for Perfluorooctanoic Acid. They are water and stain-resistant  7 nov. 2019 Données existantes sur les eaux de consommation, eaux de surface, eaux souterraines ;. • PFOS et PFOA quantifiés dans de nombreux points d'  PFOS stands for perfluorooctanesulfonic acid or perfluorooctanesulfonate.

Högfluorerade ämnen upptäcktes i marken och i dricksvattnet i flera svenska kommuner under 2014. Kemikalieinspektionen och Livsmedelsverket startade då ett nätverk för myndigheter, forskare, länsstyrelser, kommuner och vatten­pro­du­center.

These studies indicate that exposure to PFOA and PFOS over certain levels may result in adverse health effects, including developmental effects to fetuses during pregnancy or to breastfed infants (e.g., low birth weight, accelerated puberty, skeletal variations), cancer (e.g., testicular, kidney), liver effects (e.g., tissue damage), immune effects (e.g., antibody production and immunity), thyroid effects and other … Background: Perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) are two fluorinated compounds widely used in industry because of their useful chemical characteristics. They were identified as endocrine disruptors due to their ability to interfere with thyroid function.

Den fisk som riskerar ha de högsta halterna av PFOS är fisk som fångas i vattendrag som ligger i områden med konstaterad PFAS-förorening. väl underbyggt underlag för PFOS. Även för PFOA ser vi möjligheter att få fram ett tillräckligt underlag för att ta fram generella riktvärden med kompletterande insatser i ett senare skede.

PFOS and PFOSA as further in-depth evaluation of the extensive database of original literature was outside the scope of the project. The report has been elaborated according to the general practice laid down in PFOA and PFOS are found 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. Perfluorerte stoffer (PFAS-er) er svært stabile og hoper seg opp i mennesker og miljø over hele verden.
