IntroductIon Perfluorinated acids (PFAs), including PFOA and PFOS, are widely distributed pollutants in the environment.1 PFOS and PFOA are a class Se hela listan på environmentalpollutioncenters.org Perfluorooctane sulphonate (PFOS) and Perfluorooctanoic acid (PFOA) are perfluorinated chemicals which historically have had a wide range of uses including polymer precursors, certain fire-fighting reaching 0.997. The limits of detection (LODs) for PFOA and PFOS were at sub-ng/L levels in water, and at ng/kg levels in soil. The average spiking recoveries in pure water, river water, and wastewater at 2.5, 40, and 200 ng/L ranged from 88.4 to 98.8 %, and from 88.0 to 97.3 % for PFOA and PFOS, respectively, with all RSD values PFOS is an exceptionally stable compound in industrial applications and in the environment because of the effect of aggregate carbon–fluorine bonds.

Only two of the areas the EWG tested—Brunswick County, North Carolina and Quad Cities, Iowa—had tap water samples that exceeded EPA limits for PFOS and PFOA. Two of these PFAS chemicals, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), have been the most extensively produced and studied.

Don't boil your water. 2 Boiling water that contains PFOA/PFOS will actually concentrate the contaminant. Follow the advice of your municipal water authority regarding using water for drinking, cooking, bathing, dish washing, providing to pets or filtering during the advisory.

Groundwater that is affected by PFOA or PFOS is often polluted by soil and air contamination. Surface water can be affected when the chemicals used in manufacturing facilities enter directly into a water source. Water supplies can also be contaminated by wastewater from washing pots, pans, utensils and fabrics made using PFOS/PFOA chemicals.

It is found in soil, air and water. Workers who used or produced PFOS may have breathed in mists or have had direct skin contact. The general population may be exposed by dermal contact with fabrics treated with PFOS. Because PFOS is now found everywhere in the environment, people are exposed through food, in particular fish, and house dust. WASHINGTON (Feb.
