Air Quality Alerts Issued Across Midwest Due to Ozone and Wildfire Smoke

High ozone levels and smoke from Canadian wildfires have led to air quality alerts and hazy skies in Chicago. Over 160 wildfires are burning in Quebec, contributing to the hazy conditions. Ground-level ozone is also a concern, with the Illinois EPA issuing a statewide air quality alert and Air Pollution Action Day. Active people and those with respiratory or pulmonary disorders are particularly at risk, and everyone should limit outdoor activity. Hazy conditions are expected to remain until Tuesday.
