Several Pennsylvania cities place among the top 25 most polluted in the U.S., according to the American Lung Association, which uses data from the Environmental Protection Agency.

The rise in use of natural gas over coal has contributed to a decrease in particulate matter in Pennsylvania’s air. A 2015 report by the United Health Foundation, using EPA data, showed that the state’s air pollution — measured by the public’s exposure to particulate matter — decreased each year but one since 2003.
