U.S. Environmental Protection Agency ( EPA ) is launching a global stewardship program inviting companies to reduce PFOA ( Perfluorooctanoic acid ) releases and its presence in products by 95 percent by no later than 2010 and to work toward eliminating sources of exposure five years after that but no later than 2015.
PFOA is an essential processing aid in the manufacture of fluoropolymers, which are used in the manufacture of a wide range of non-stick and stain-resistant surfaces and products. PFOA may also be produced by the breakdown of fluorotelomers, which are used to impart water, stain, and grease resistance to carpets, paper and textile.
PFOA is persistent in the environment, it has been detected in low levels in wildlife and humans, and animal studies conducted have indicated effects of concern.
Participating companies will commit to reduce by 95 percent facility emissions and product content levels of PFOA, PFOA precursors, and higher homologue chemicals, by no later than 2010, with the year 2000 as the baseline for measuring reductions. The program also calls for companies to commit to work toward eliminating these sources of PFOA exposure five years after attaining the 95 percent reduction but no later than 2015. Companies are being asked to meet these commitments in the United States as well as in their global operations.
PFOA, also known as C8 or Ammonium Perfluorooctanoate ( APFO ), is used in the manufacturing process of fluoropolymers. Fluoropolymers impart desirable properties, including fire resistance and oil, stain, grease, and water repellency. They are used to provide non-stick surfaces on cookware and waterproof, breathable membranes for clothing. PFOA can also be found as an impurity in the production of some products.
