The Junk Science of George W. Bush: “On September 13, just two days after the terror attack, the EPA announced that asbestos dust in the area was ‘very low’ or entirely absent. On September 18 the agency said the air was ‘safe to breathe.’ In fact, more than 25 percent of the samples collected by the EPA before September 18 showed presence of asbestos above the 1 percent safety benchmark. Among outside studies, one performed by scientists at the University of California, Davis, found particulates at levels never before seen in more than 7,000 similar tests worldwide.”
