Air quality alert extended to 5th day due to Canadian wildfires

An Air Quality Alert due to smoke from Canadian wildfires is extended to Saturday for most of the region and through Sunday for Butler and Warren counties.

Smoke from the wildfires contains fine particulates, which can be inhaled into your lungs and cause irritation of the eyes, nose or throat, coughing, shortness of breath, and chest pain; and can also aggravate chronic heart and lung conditions, said Ohio Department of Health Director Dr. Bruce Vanderhoff.
