voluntary industry phase-out of PFOA, whereby the major global fluorochemical companies have agreed to eliminate PFOA by 2015. Well-known consumer products have helped bring these issues into public awareness. In 2000, 3M stopped making PFOS and eliminated it from their ScotchgardTM fabric protector. In 2003, PFOS, PFOA, AND OTHER FLUOROCHEMICALS

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

These substances are synthetic compounds that are unique for being water and lipid-resistant. 2020-09-01 · Zeng et al. (2019b) looked at the association between serum PFOS and PFOA levels and serum uric acid, and found that for both PFOA and PFOS the branched isomer had a higher increase in serum uric acid per log unit, but a starker difference was seen between PFOS and PFOA; each log increase of serum PFOS concentration was associated with increases of 0.09 mg/dL and 0.06 mg/dL, respectively, but Technical Fact Sheet – Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) This fact sheet provides a summary of two contaminants of emerging concern, perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), including physical and chemical properties; environmental and health impacts; existing federal and state guidelines; Eurofins | BLC PFOA / PFOS testing services – Leather and textile testing. 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).

What is Perfluorooctane sulfonic acids (PFOS)? Perfluorooctane sulfonic acids (PFOS) are anions that are commercially available in the form of salts, derivatives and polymers. The major uses for PFOS-related substances are in providing grease, oil and water resistance to materials such as textiles, carpets, paper and in general coatings. In 2012 the US EPA published its first lifetime health advisories (LHA) for two of these chemicals, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), at … 2019-11-22 PFOA.
