Iowa DNR report shows improvements in Iowa’s air quality since 1978

Air quality in Iowa has improved dramatically over the past five decades according to a recent report by the Iowa Department of Natural Resources.

The report – Ambient Air Quality Improvements in Iowa – finds that harmful air pollutants such as sulfur dioxides and nitrogen oxides have declined, 60 percent and 43 percent respectively, since 1978. Both compounds can lead to respiratory issues and sulfur dioxide can contribute to acid rain. These health effects can be especially harmful to children, the elderly, those with lungs diseases, and those who exercise outdoors.

In 1978, 13 Iowa counties recorded air pollution levels that exceeded National Ambient Air Quality Standards (NAAQS) compared to just two counties in 2015: Muscatine and Pottawattamie. Council Bluffs, the county seat in Pottawattamie County, exceeded NAAQS standards for lead particles in the air in 2010 and 2012 but those levels were below the NAAQS standards from 2013 to January of 2016. Muscatine, the county seat in Muscatine County, experienced unsafe levels of fine particulate matter in the air in 2009 and 2010 but those levels have since declined. Additionally, data in Muscatine showed excessive levels of sulfur dioxide in 2008 and 2010 but levels have also declined since 2010.

The reductions in harmful air pollutants across the state has in part been attributed to newer, more efficient equipment and technology. Despite the overall improvements in Iowa’s air quality, the state’s productivity, population, and travel miles have increased since 1978, all of which can be potential sources contributing to air pollution.

Industrial Muscatine continues to struggle with air pollution, health affects

An Iowa town with the worst air quality in the state is again under EPA scrutiny after years of maintaining allowable air pollution levels.

But plans to clean up emissions from burning coal won’t be adopted for several years, leaving residents in a haze of regulation and red tape.

Last month, the EPA declared Iowa’s pollution-fighting plans “substantially inadequate” for maintaining fine particulate matter standards in Muscatine, an industrial town on the Mississippi River. Continue reading

Muscatine, Council Bluffs cited for dirty air

Oooh, that smell. Can’t you smell that smell? Last week residents in Muscatine and across the state in Council Bluffs may have caught a whiff of something because both cities were cited for exceeding EPA air pollution limits.

Muscatine had too much sulfur dioxide wafting through its air, and Council Bluffs had too much lead.

Those unconcerned with air quality may contend that the true problems in these cases are associated with more stringent regulation. Last August the EPA’s allowance of sulfur dioxide grew stricter and in October 2008 strictness for the lead standard increased tenfold.

But both forms of pollution are regulated for a reason. Short-term exposure to sulfur dioxide can increase the likelihood of contracting asthma, bronchitis, emphysema or other lung and heart disease. And it can worsen the symptoms of those who already have such conditions. Continue reading
