On 29 Sept Gov. Schwarzenegger vetoed Senate Bill 1313, by Sen. Ellen Corbett, which was sponsored by Environmental Working Group (EWG). It would have banned, starting in 2010, the perfluorinated chemicals PFOS & PFOA from fast-food sandwich wrappers, french-fry bags, pizza boxes & other food packaging. Studies show these chemicals can migrate into food directly from the packaging, especially when heated. PFOS & PFOA have been found in more than 98% of Americans' blood, & an EWG study detected the chemicals in the umbilical cord blood of 10 of 10 newborn babies. PFOA & PFOS never break down, persisting in the environment indefinitely. PFOA is considered by the U.S. EPA's Science Advisory Board to be a likely carcinogen & a chemical that induces breast tumors in animals. In addition, PFOA & PFOS have been linked to problem pregnancies & developmental complications
