Thick smoke from over 800 Canadian wildfires has drifted across the border, triggering widespread air quality alerts for millions of residents in the Midwest and Northeast regions of the United States.
Air Quality Alerts Issued
Conditions worsened significantly between Wednesday and Thursday morning. Officials issued air quality alerts across several states, including Connecticut, Delaware, Massachusetts, Michigan, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, and Wisconsin. By Thursday morning, Minneapolis and Duluth, Minnesota, alongside Detroit, recorded Air Quality Index (AQI) levels exceeding 340.
According to meteorologists, the primary source of the smoke stems from dozens of out-of-control blazes in western Ontario, many of which are believed to have been started by lightning. Additional fires in Manitoba, Saskatchewan, and the Northwest Territories are also contributing to the upper-atmosphere haze.
Medical professionals warned that sustained exposure to these conditions carries notable health risks. “When the AQI climbs into the 150+ range for a full day outside, that’s in the ballpark of [smoking] 7 to 9 cigarettes,” said Dr. Jonathan M. Tan, division chief of General Anesthesiology at Children’s Hospital of Philadelphia.
Health officials recommend that the public, particularly sensitive groups, limit their time outdoors and avoid outdoor exercise to minimize symptoms like throat irritation, itchy eyes, and breathing difficulties.
