Perfluorinated chemicals (PFCs) are a family of fluorinated organic compounds that are manufactured to give coatings like Teflon® and Scotchgard® their nonstick and water- and stain-repellent qualities. These coatings are used on cookware, carpets, clothing, shoes, bedding, mattresses and upholstered furniture. PFCs have also been used in food wraps, sprays for leather and shoes an, paints and cleaning products, shampoo, floor wax, dental floss and some cosmetics. (For a listing of products, see Environmental Working Group’s Shopper’s Guide to PFCs
PFCs are extremely persistent once they are released into the environment, accumulating in humans and wildlife. They can remain in human tissue for many years.
PFCs have fallen under scrutiny from the U.S. Environmental Protection Agency (EPA) since the late 1990s, when widespread low-level contamination was found in blood samples from the U.S. general population, in wildlife and in the environment.
In 2000, after reaching an agreement with EPA, 3M phased out production of Scotchgard products containing the PFC called perfluorooctane sulfonate (PFOS). (3M introduced new formulations of Scotchgard without PFOS in 2003.) (OSF: http://www.ourstolenfuture.org/Commentary/News/2003/2003-0622-SJMN-scotchgardreturns.htm)
EPA is investigating a similar perfluorinated chemical, perfluorooctanoic acid (PFOA, also known as C8), the active ingredient in Teflon nonstick coatings. A preliminary report, issued January 2005, raises concerns that people may face risks of developmental and other adverse effects from low-level exposure to PFOA based on animal studies. (EPA Draft Risk Assessment)
EPA has also assessed fines against DuPont for hiding information and studies that linked potential health risks to its workers and communities surrounding its plants. (Washington Post)
Children may be exposed through normal use of PFC-coated products. In addition, nonstick pans heated at high temperatures may give off fumes. To avoid fumes, do not heat empty pans or use them in the oven.
