2011 air quality report released for Illinois


The Bureau of Air's Annual Air Quality Report for 2011 has been released by the Illinois Environmental Protection Agency.

Last year, air quality in Illinois was either good or moderate for over 92 percent of the time. No "unhealthy" days were recorded, but there were 31 days in which the air quality was "unhealthy for sensitive groups."

Over the last ten years, trends show overall decreases in pollutants for which quality standards have been made. Those include ozone, sulfur dioxide, carbon monoxide, and lead.

"We are proud of the achievements Illinois has made in terms of air quality," Illinois EPA Interim Director John Kim said. "While air quality standards continue to become more stringent, the Illinois EPA remains committed to meeting all current and future standards and is dedicated to continually improving air quality."

Nine monitoring locations and 41 monitors were discontinued in Illinois last year, all within areas in which ambient air quality has been well within National Ambient Air Quality Standards. Despite the reduction in monitoring locations, the state still meets U.S. EPA regulations.
