PFAS
The per-and polyfluoroalkyl substances PFAS are a group of chemicals used to make fluoropolymer coatings and products that resist heat oil stains grease and water. PFAS are used in industries such as aerospace automotive construction.

Fluoropolymer coatings can be in a variety of products.
. Clothes labeled stain- or water-repellent such as Gore-Tex jackets usually contain PFAS chemicals. PFAS are bioaccumulative meaning they build up in the bloodstream and tissue. Per- and polyfluoroalkyl substances PFASs are synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain.
An early definition from 2011 required that they contain at least one perfluoroalkyl moiety C n F 2n1. More recently 2021 the Organisation for Economic Co-operation and Development OECD expanded the definition. Read more about the proposed rule.
Per- and polyfluoroalkyl substances PFAS are chemicals that have been used in a wide range of consumer and industrial products since the 1940s due to their resistance to grease oil water. PFAS are a large complex and ever-expanding group of manufactured chemicals that are widely used to make various types of everyday products. PFAS are found in water air fish and soil at locations across the nation and the globe.
On August 26 2022 EPA issued a proposal to designate two of the most widely used PFAS as hazardous substances under CERCLA or Superfund. Since at least the 80s research has found links between PFOS and PFOA 2 common PFAS chemicals and a number of health problems such as. There are thousands of PFAS chemicals and they are found in many different consumer commercial and industrial.
PFAS may be listed on the ingredient list as PTFE polytetrafluoroethylene perfluorooctyl triethoxysilane perfluorononyl dimethicone perfluorodecalin and perfluorohexane. 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.
Scientific studies have shown that exposure to some PFAS in the environment may be linked to harmful health effects in humans and animals. For example they keep food from sticking to cookware make clothes and carpets resistant to stains and create firefighting foam that is more effective. This rulemaking would increase transparency around releases of these harmful chemicals and help to hold polluters accountable for cleaning up their contamination.
These include clothing furniture adhesives food packaging heat-resistant non-stick cooking surfaces and the. More recent research is establishing some of the same. PFAS have been designated a public health concern by the Agency for Toxic Substances and Disease Registry ATSDR and growing concern over potential toxicity and persistence of PFAS in the environment has led the Environmental Protection Agency EPA to develop a multi-faceted scientific and regulatory approach to protect human and ecological.
