Air Quality Alerts Issued Across Midwest Due to Wildfire Smoke.

The National Weather Service and Michigan Department of Environment, Great Lakes, and Energy declared an Air Quality Alert day on Tuesday for elevated levels of fine particulate due to more wildfire smoke from Canada moving into the region. The pollutants are expected to be in the “unhealthy for sensitive groups” range with some hourly concentrations reaching “unhealthy” level. Sensitive groups, such as people with lung disease (including asthma), heart disease, and children and older adults, should limit prolonged or heavy exertion.
