Ozone Season is Upon Us 

March is the official start of ozone season. The Southwest Ohio Air Quality Agency is required by U.S. EPA to monitor and report ozone concentrations each year from March 1 through October 31.

Ozone is a secondary air pollutant which means it is a combination of other air pollutants such as nitrogen oxides and volatile organic compounds. These pollutants come predominantly from vehicle exhaust and industrial emissions. In the presence of sunlight and warmer temperatures, nitrogen oxides and VOCs combine to form ozone.

Ozone can be harmful to people’s lungs, especially those who have asthma or other respiratory illnesses. When ozone concentrations exceed good or moderate levels, the Agency issues an Air Quality Alert, a public message designed to raise awareness of elevated air pollution.

Our region typically experiences Air Quality Alerts from May through August, when summer weather conditions are ideal for higher ozone concentrations. Be prepared now by signing up for Enviroflash, a free service that emails or texts you when an Air Quality Alert is issued.
