INDIANAPOLIS - Marion County is tied for the 24th most polluted county in the United States, according to a report released Wednesday by the American Lung Association.
The State of the Air 2013 report found that the Indianapolis metro area also received an "F" for short-term particle pollution and that the ozone levels in Marion County were downgraded from a "C" to a "D".
Health experts said these pollution levels can cause wheezing, coughing, asthma attacks and premature death.
ALA Manager of Mission Services Meghan McNulty said that Indy's air quality is better than it was a decade ago, but there's still a long way to go.
"We must set stronger health standards for pollutants and cleanup sources of pollution in Indianapolis to protect the health of our citizens," McNulty.
The American Lung Association in Indiana urges the public to join the fight for clean air and to learn how to protect themselves and their families from air pollution by visiting www.stateoftheair.org.
