Riskbedömning PFAS - SGI - Statens geotekniska institut
Health Advisories. EPA has established health advisories for PFOA and PFOS based on the agency’s assessment of the latest peer-reviewed science to provide drinking water system operators, and state, tribal and local officials who have the primary responsibility for overseeing these systems, with information on the health risks of these chemicals, so they can take the appropriate actions to PFOS refers to Perfluorooctane Sulfonate and PFOA stands for Perfluorooctanoic Acid. They are water and stain-resistant synthetic compounds that are difficult to break down in the environment and in the human body. Why are PFOS and PFOA still a concern today if these chemicals are no longer in production? Technical Fact Sheet – Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) The chemicals PFOA and PFOS were widely used to make carpets, clothing, fabrics for furniture, paper packaging for food and other materials that are resistant to water, grease or stains.

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.

Used as early as the 1940s, PFAS were once thought of as beneficial because of their ability to repel Perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexane sulfonate (PFHxS) belong to this group of chemicals. These chemicals are very stable and do not break down in the environment. They can persist for a long time both in the environment and in humans. 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. Till de kortkedjiga PFAS hör PFHxA (perfluorhexansyra) och PFHxS (perfluorhexansulfonat) som båda består av 6 kol och hör till den så kallade C6-kemin. PFOS är ett av flera tusen PFAS-ämnen och för närvarande det värsta av dem som man känner till. Det är det enda PFAS-ämne som är förbjudet i EU. Vissa företag som fasat ut PFOS och PFOA (ett annat misstänkt cancerframkallande PFAS-ämne) ur sina produkter kan ibland i sin marknadsföring ge intrycket av att de är PFAS-fria.
