The European Union has banned PFOS and is considering similar action with PFOA.

Table 3.2: Technical An assessment of the significance of PFOA-related substances to the overall list of PFOA-related substances, similar to the current EU restriction of PFOS. Well-studied members of the perfluoroalkyl family, including perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), have been shown to be highly Perfluorooctane sulfonate (PFOS) is a long-chain PFAS found in older stocks of AFFF and as a breakdown product of precursor compounds.

PFOS, a halogenated hydrocarbon, is toxic to humans, and also both carcinogenic and mutagenic. Swedish62 % av kolmonoxidemissionen, 50 % av kväve-, 33 %

First off, most nonstick pans should not be used to cook at high heats. While PFOA exposure via PTFE cookware is not a major concern, almost all nonstick pans contain fluorine, a chemical that burns off when overheated. Pfos and PFOA Pfos and PFOA are man-made chemicals belonging to the group known as Per- and poly-fluoroalkyl substances.

Avoid products that could contain PFOs and PFOA such as non-stick cookware or coated food packaging. Even if the use of these chemicals is restricted in the US, they are still used in other countries, so there is an elevated risk of contamination if the products were produced abroad. PFOS and PFOA have been extensively produced and studied in the United States. These manmade substances have been synthesized for water and lipid resistance. They have been used extensively in consumer products such as carpets, clothing, fabrics for furniture, paper packaging for food, and other materials (e.g., cookware) designed to be A recent halflife analysis was conducted on 9 retired 3M chemical workers.

Over the past decade, there has been growing concern over two environmental contaminants known by the cryptic acronyms PFOS and PFOA. These man-made chemicals were once used to manufacture a diverse collection of consumer goods, ranging from pizza boxes to stain-resistant carpets to teflon pans. Now PFOS and PFOA have worked their way into the soil, air and water, invading even the most remote

Both are toxic and PFOA has been identified by preliminary government-risk assessment as being consistent with the category of a “likely carcinogen.” PFOA (perfluorooctanoic acid) is a synthetic chemical compound that is used, along with PTFE, to manufacture certain fluoropolymer and telomer-based products, including nonstick pan coatings like Teflon. However, officials have not regulated any new contaminant in two decades, meaning that the regulation of PFOA is (likely) many years away. Health Impacts of PFOA and PFOS Exposure. Unfortunately, the information regarding the health consequences of PFOS and PFOA has been slow to appear.

Why are PFOS and PFOA still a concern today if these chemicals are no longer in production? PFOS was voluntarily phased out of production in the United States by 3M, its main manufacturer, starting in 2000. In 2006, PFOA began to be phased out as well.

PFOS (meaning they shares structural similarities). Commercially, it has been used as a replacement for PFOS in various formulations. PFECHS, similar to other long-chain PFAS, has been reported in environmental media around the world. Found in drinking water [1], wastewater [2], surface water [3-
