Indiana Air Quality Shows Mixed Results, Finds 2016 ‘State of the Air’ Report
Despite continued improvement in air quality, local residents remain at risk from health effects of unhealthy air, according to new report from the American Lung Association

The American Lung Association’s 2016 “State of the Air” report found the Louisville, KY-IN region ranked as the 10th-most polluted area in the nation for annual particle pollution while Indianapolis, IN ranked 13th and the Cincinnati, OH-KY-IN region ranked 14th. South Bend, IN also ranked as on the cities with the highest average number of days of unhealthy short term particle levels. Compared to the 2015 report, Indianapolis has cut levels of dangerous ozone pollution. This is in keeping with a trend seen across the nation of lower ozone pollution levels.
“The 2016 ‘State of the Air’ report finds unhealthful levels of ozone and particle pollution in Indiana with at least 21 counties registering a failing grade in at least one category, putting our local citizens at risk for premature death and other serious health effects such as asthma attacks and cardiovascular harm,” said Michael Kolleng, Healthy Air Campaign Manager of the American Lung Association. “Across the nation, the report found continued improvement in air quality, but more than half of the people in the United States live in counties that have unhealthful levels of either ozone or particle pollution.”
Each year the “State of the Air” reports on the two most widespread outdoor air pollutants, ozone pollution and particle pollution. The report analyzes particle pollution in two ways: through average annual particle pollution levels and short-term spikes in particle pollution. Both ozone and particle pollution are dangerous to public health and can be lethal. But the trends reported in this year’s report, which covers data collected in 2012-2014, are strikingly different for these pollutants nationwide, and also in Indiana.
Ozone Pollution in Indiana
Compared to the 2015 report (2011-2013), Indiana counties in the Chicagoland, Cincinnati, and Louisville areas as well as Indianapolis and South Bend experienced fewer unhealthy days of high ozone.
“Ozone is harmful to public health and especially children, older adults and those with asthma and other lung diseases,” said Kolleng. “When older adults or children with asthma breathe ozone-polluted air, too often they end up in the doctor’s office, the hospital or the emergency room.”
Nationwide, ozone pollution has decreased because the nation has cleaned up major sources of the emissions that create ozone, especially coal-fired power plants and vehicles. However, according to research, climate change causes warmer temperatures, which makes ozone harder to clean up.
Particle Pollution in Indiana
The 2016 report also found year-round particle pollution (soot) levels in 2012-2014 slightly lower than the 2015 report except in the South Bend-Elkhart-Mishawaka area. Nationwide, the best progress in this year’s report came in reducing year-round levels of particle pollution. In fact, Indianapolis reached their lowest levels ever reaching compliance with the national standard.
“Particle pollution is made of soot or tiny particles that come from coal-fired power plants, diesel emissions, wildfires and wood-burning devices. These particles are so small that they can lodge deep in the lungs and trigger asthma attacks, heart attacks and strokes, and can even be lethal,” said Kolleng. “Year-round particle pollution levels have dropped thanks to the cleanup of coal-fired power plants and the retirement of old, dirty diesel engines.”
The 2016 report also tracked short-term spikes in particle pollution, as these can be extremely dangerous and even lethal. According to the 2016 report, Indianapolis and other metro areas had fewer days when short-term particle pollution has reached unhealthy levels in 2012-2014. This is in keeping with a trend seen across the nation of short-term spikes in particle pollution. South Bend, IN saw an increase in short term particle pollution, and achieved its highest ranking on the list of unhealthy cities for particle pollution.
Increased heat, changes in weather patterns, drought and wildfires are all related to climate change, which has contributed to the extraordinarily high numbers of days with unhealthy particle pollution in some cities in Indiana.
“If we can do more to save lives—we should, and we can,” Kolleng said. “The Lung Association in Indiana calls on the state of Indiana to adopt a strong Clean Power Plan to reduce harmful emissions from power plants that worsen climate change and immediately harm health.”
