PFCs apparently do not have the extreme toxicity of, say, dioxins; nevertheless, there's little reason for complacency when compounds that can be found so readily in such a broad range of animals -- mammals, birds, and reptiles -- have also been shown to damage the health of the few species on which they have been tested. Turning up the heat on DuPont Since 2000, the federal government, environmental groups, and private citizens have been steadily turning up the heat on DuPont with a series of lawsuits and proposed regulatory actions in states across the nation: Stewardship, not elimination In early 2006, DuPont and seven other companies signed on to a voluntary "PFOA Stewardship Program" under which they pledged to reduce emissions of PFOA from their factories by 95 percent by the year 2010. They will also achieve a 95 percent reduction in PFOA contamination of their products by 2010 and eliminate the chemical from products and emissions by 2015.
