The American Lung Association’s 2016 “State of the Air” report found the Davenport area ranked as the 112th-most polluted city in the nation for ozone pollution. Compared to the 2015 report, Davenport has seen an increase in unhealthy ozone days. This is in spite of a trend seen across the nation of lower ozone pollution levels. Des Moines-Ames0 West Des Moines was rates one of the cleanest areas for short term-particle pollution.

“The 2016 ‘State of the Air’ report finds unhealthful levels of ozone and particle pollution in many counties in Iowa, putting 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 Iowa.

Ozone Pollution in Iowa
Compared to the 2015 report (2011-2013), Davenport experienced more unhealthy days of high ozone in this year’s report. This resulted in a failing grade for Clinton County. Harrison and Van Buren counties also registered failing grades for ozone pollution. Some areas in Iowa did see improvement in line with national trends, especially in the greater Omaha NE-IA area.

“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 Iowa
The 2016 report found year-round particle pollution (soot) levels in 2012-2014 lower than the 2015 report. Nationwide, the best progress in this year’s report came in reducing year-round levels of particle pollution. In fact, the Omaha-Council Bluffs-Freemont, NE-IA (Pottawattamie County) reached their lowest levels ever, improving over the period covered by the 2015 report. 

“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, Scott County has more days when short-term particle pollution has reached unhealthy levels in 2012-2014. This is in spite of a trend seen across the nation of short-term spikes in particle pollution.

Increased heat, changes in weather patterns, drought and wildfires are all related to climate change, which has contributed to the numbers of days with unhealthy particle pollution in some cities in Iowa.  Many of these spikes in Iowa were directly linked to weather patterns like drought, which are likely to increase because of climate change.

“If we can do more to save lives—we should, and we can,” Kolleng said. “The Lung Association in Iowa calls on the state of Iowa to adopt a strong Clean Power Plan to reduce harmful emissions from power plants that worsen climate change and immediately harm health.”
