FTOH is a by-product of most water repellents, even those that are PFOS-free and PFOA-free. So instead of removing individual fluorochemicals as potential health and safety concerns 2020-01-24 · Some of the most commonly used PFAS chemicals, like PFOS and PFOA (perfluorooctanesulfonic acid and perfluorooctanoic acid) have long half-lives, earning them the moniker “the forever chemical.” PFOA, PFOS and the related phased-out compounds are called “long chain” chemicals because they contain eight carbon atoms. Since these chemicals have been phased out, the EPA and the Food and Drug Administration have recklessly allowed the introduction of scores of “short chain” replacements, with six carbon atoms. use PFASs other than PFOS; however, existing stocks of PFOS-based AFFF remain in use.

PFAS chemicals are widely used to coat paper and cardboard wrappers for fast food and bakery goods. PFAS chemicals lurk in stain-resistant furniture and carpets treated with Scotchgard, Stainmaster and other fabric treatments. Clothes labeled stain- or water-repellent, such as Gore-Tex jackets, usually contain PFAS chemicals. PFOS and PFOA are stable chemicals that are comprised of chains of eight carbons.

Most people are familiar with it as a non-stick coating surface for pans and other cookware. It is also used in many other products, such as fabric protectors. Perfluorooctanoic acid (PFOA), also known as C8, is another man-made chemical.

What Are PFAS? Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that include Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA). These elements have a negative effect on the health of those exposed to them. PFOS and PFOA stand for perfluorooctane sulfonate and perfluorooctanoic acid, respectively. Both are fluorinated organic chemicals, part of a larger family of compounds referred to as perfluoroalkyl substances (PFASs). These substances are synthetic compounds that are unique for being water and lipid-resistant.
