Centers for Disease Control report showed significant reductions in human blood levels of PFOS and PFOA from 1999/2000 compared to the most recent data in 2003/2004 in a representative sample of the US population - The geometric mean for PFOA was reduced by 25% over this period; PFOS by 32% - Report concludes that these reductions most likely are related to the changes brought about by EPA efforts on these chemicals and other related efforts by government and industry 4 US00007940 PFOA Stewardship Program: Overview In January 2006, EPA invited eight major companies in the fluoropolymer and fluorotelomer industries to commit to a voluntary program with global goals; companies accepted invitation by March 1,2006 Participating companies: Arkema, Asahi, Ciba, Clariant, Daikin, DuPont, 3M/Dyneon, Solvay Solexis Companies submitted baseline year data on emissions and product content in Oct 2006; progress reports in Oct. 2007 - Report period: baseline year to end of 2006 - Submitted both non-CBI and CBI reports Report annual progress toward goals each succeeding October 5 US00007941 PFOA Stewardship Program: Goals 1.
