PFOS testing can be carried out by Eurofins | BLC to accurately test leather and textiles to 1µg/m 2 using Liquid Chromatography – Mass Spectrometry (LC-MS). 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 effects (e.g., cholesterol changes). The concentration of PFOA + PFOS has risen to 30 ppt in the effluent from the lag GAC vessel, amounting to about 50% breakthrough based on combined influent level of 61 ppt. At the same time, non-detect levels for PFOA and PFOS were still being measured at both the mid-point and exit points of the resin bed, corresponding to EBCTs of 1.4 and 2.8 minutes and to bed volumes treated of 168,000 PFOS är dessutom lösligt i vatten, vilket gör att ämnet inte stannar kvar i den förorenade källzonen, utan sprider sig till våra vattendrag, sjöar och brunnar. I larmrapporterna från 2014 uppgavs att drygt 3 miljoner av Sveriges invånare är drabbade av dricksvatten förorenat av högfluorerade ämnen som tidigare förekom i brandsläckningsskum.

Perfluorooctanoic acid (PFOA) and Perfluorooctane sulfonate (PFOS) are part of the larger group of PFAS chemicals. While no longer manufactured in the United States, PFOA and PFOS were extensively used and manufactured since the 1940’s. What are PFOA, PFOS, and PFAS? Perfluorooctanoic acid and perfluorooctane sulfonate–more commonly referred to as PFOA and PFOS, respectively–are fluorinated organic compounds that are part of larger group of compounds known as perfluoroalkyl substances (PFAS). These man-made chemicals are infamous for being both water and lipid-resistant. For drinking water, in 2009, the EPA released provisional health advisories (PHAs) for PFOA and PFOS, which recommended actions to reduce exposure when contamination reaches 0.4 µg/L for PFOA and 0.2 µg/L for PFOS.

Jul 31, 2018 Internal studies and other documents show that 3M knew by the 1970s that PFOA and PFOS were toxic and accumulating in people's blood.

PFHxA: Perfluorhexansyra. PFHpA: Perfluorheptansyra.

PFOA and PFOS are extremely persistent in the environment and resistant to typical environmental degradation processes. [They] are widely distributed across the higher trophic levels and are found in soil, air and groundwater at sites across the United States.

PFOS je považován za perzistentní organickou látku, má silnou schopnost hromadit se v organismu a byl nalezen v tělech ryb, ptáků, savců i lidí. Na zvířatech bylo prokázáno, že může poškodit játra, narušit rozmnožování nebo způsobit poruchu vývoje plodu.

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. However, the EPA has established health advisories for PFOA and PFOS in drinking water, based largely on the health effects of PFOA and PFOS seen in studies of lab animals (rats and mice). The health advisory level for both of these chemicals (alone or combined) is set at 70 parts per trillion over the course of a person’s lifetime.

Till de kortkedjiga PFAS hör PFHxA (perfluorhexansyra) och PFHxS (perfluorhexansulfonat) som båda består av 6 kol och hör till den så kallade C6-kemin.

Apr 3, 2017 Perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexane sulfonate (PFHxS) belong to this group of chemicals. PFOS and PFOA · PFOS – Perfluorooctane sulfonate (PFOS) was the key ingredient in the stain repellant Scotchgard, and was used in surface coatings for Eurofins | BLC PFOA / PFOS testing services – Leather and textile testing · Footwear · Clothing · Bags and luggage · Leathergoods · Jewellery · Upholstery. The data did not reveal significant occurrences of PFOA or PFOS in Virginia; however, UCMR 3 had reporting limits of 20 parts per trillion (ppt) and 40 parts per Jul 31, 2018 Internal studies and other documents show that 3M knew by the 1970s that PFOA and PFOS were toxic and accumulating in people's blood. Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that include PFOA, PFOS, GenX, and many other chemicals. PFAS have been Jun 28, 2019 To establish MCLs for PFOA, PFOS, PFHxS and PFNA, NHDES had to consider the extent to which the contaminants are found in New Mar 11, 2019 PFAS are a large group of synthetic chemicals that include perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS) and thousands of The EPA set a lifetime health advisory (LHA) level for two PFAS in drinking water, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS).
