LANSING – Michigan has reduced overall air pollution since 2012, but its most populous counties still don’t earn a passing grade, according to a new report from the American Lung Association. Its State of the Air report provides grades of A to F in two areas: particle pollution and ozone action days. The Department of Environmental Quality (DEQ) declares ozone days when smog and weather conditions create the risk of health problems.
Wayne and Macomb counties received failing grades in the ozone day category. Other counties that failed include Allegan and Muskegon, while Oakland, Ottawa and St. Clair received Ds.
