So fittingly, the American Lung Association recently released the State of the Air 2010, a report that compares the pollution of cities, counties, and states across the country. Although Georgia has shown improving air quality over the past few years, it still contains some of the worst-performing areas. Metro Atlanta ranks 16th for year-round particle pollution and 19th for ozone pollution.
See ARC’s air quality page for more information on air quality in the Atlanta region. Also, check out this Journal of the American Medical Association paper on the observed benefits in public health (specifically decreased childhood asthma hospitalizations) related to decreased VMT and increased transit usage during the 1996 Summer Olympics.
