The American Lung Association released a report April 25 concluding that more than 127 million people, or 41 percent of Americans, live in a county that exceeded air quality standards for ozone or particulates from 2008 to 2010. The annual report, State of the Air 2012, found that the Environmental Protection Agency’s air monitors in 235 counties exceeded the national ambient air quality standards for ozone, annual, or daily particulate matter, but suggested that air quality is improving due to Clean Air Act standards.
