The American Lung Association's State of the Air 2013 report, released last week, finds that air quality nationwide continues the long-term trend to much healthier air. The strongest progress came in lower levels of year-round particle pollution across much of the nation. Still, many cities that ranked among the most polluted had more unhealthy days of high ozone and short-term particle pollution than in the 2012 report.

Jay Turner, PhD, associate professor of energy, environmental and chemical engineering, is available for comment. Turner is working on solutions to our nation's pressing air quality problems.

Turner's research focuses on air quality characterization with emphasis on fine particulate matter measurements and data analysis. He was the Principal Investigator of the EPA-funded St. Louis – Midwest Fine Particulate Matter Supersite, and is currently working with stakeholders in several states on technical aspects of their fine particulate matter air quality management and planning processes.
