Cincinnati made rank in a listing of the Top 10 most polluted cities in America by the American Lung Association.
The 2013 State of the Air report lists three Midwestern cities as tied for the 10th spot: Cincinnati, Middletown, Ky. and Wilmington, Ind.
“The three Midwestern cities tie for year-round particulate pollution, thanks largely to industry and the burning of coal, which provides the bulk of electricity in the region,” according to the report.
The agency reports Cincinnati has shown improvement, with the number of days with high ozone levels falling by more than half between 1996 and 1998, then 2009 and 2011.
Topping the list of most polluted cities in America, California has eight cities listed including Bakersfield, Merced and Fresno.
