US Most Polluted Cities

April 29, 2015

More than four in 10 Americans – nearly 138.5 million people – live in counties where ozone or particle pollution levels make the air unhealthy to breathe according to The American Lung Association’s “State of the Air 2015” report released today. The 16th annual national report card shows that many cities are experiencing strong improvements, others suffer increased episodes of unhealthy air, and a few even marked their worst number of unhealthy days.iStock_000002743134Large

This year’s report also provides evidence that a changing climate will make it harder to protect human health from the dangers of air pollution. The impact of climate change is particularly apparent in the western United States, where heat and drought create situations ripe for episodes of high particle pollution, a pollutant recently found to cause lung cancer according to the report.

“Everyone has the right to breathe healthy air. We must meet our air pollution challenges head-on to protect the health of millions of Americans living with asthma and chronic obstructive pulmonary disease,” said Harold P. Wimmer, National President and CEO of the American Lung Association.

The American Lung Association “State of the Air 2015” report uses the most recent quality-assured air pollution data, collected by federal, state and local governments and tribes in 2011, 2012, and 2013. These data come from official monitors for the two most widespread types of pollution, ozone and particle pollution. The report grades counties, ranking cities and counties based on scores calculated by average number of unhealthy days (for ozone and for short-term particle pollution) and by annual averages (for year-round particle pollution).
