The average cancer risk, based on 2002 pollution levels, is 36 in a million. The agency has asserted that levels above a 100-in-a-million risk level are generally unacceptable. The data comes from a county-by-county analysis of toxic air pollution released today in a survey known as the National Air Toxics Assessment (NATA). The report covers 181 air toxics and diesel particulate matter and estimates risks from exposure to emissions from industrial sources and mobile sources such as cars and trucks. ‘The implication for me is we still have a long way to go to reduce toxic air pollution to protect the public,’ said John Walke, a senior attorney at the Natural Resources Defense Council. ‘It still shows an unacceptable number of Americans being exposed to cancer risk solely attributed to air pollution on top of all the other risks from smoking and indoor […]
