Canadian Wildfire Smoke Turns Air Hazardous in the Us Midwest

UNITED STATES- Heavy, pungent smoke from Canadian wildfires darkened skies in the U.S. on Thursday, from the Great Lakes to parts of the East Coast, reducing visibility for commuters and prompting warnings that air quality could make being outside dangerous.

Detroit’s air quality was among the worst in the world for major cities, as a lingering high-pressure system trapped smoke from dozens of fires in Canada and northern Minnesota.

Cities across the Great Lakes states registered air quality ranging from unhealthy to hazardous, which means it is unhealthy for anyone, regardless of health conditions.

Microscopic particles can lodge deep in the lungs and enter the bloodstream, leading to heart and lung problems and contributing to other long-term health issues.
