"Smoke from Wildfires Engulfs Midwest, Triggers Air Quality Alerts"

Wildfire smoke from Canada is set to return to Metro Detroit on Tuesday, prompting the Michigan Department of Environment, Great Lakes, and Energy to issue an Air Quality Alert. The alert warns of elevated levels of fine particulate matter (PM2.5) and advises residents, particularly those with respiratory concerns or health problems, to stay indoors if possible. Other tips include limiting outdoor activities, minimizing pollution-causing activities, and using alternative transportation methods. Ozone from the smoke can irritate the respiratory system, reduce lung function, and increase the risk of infection, particularly for vulnerable groups such as children, older adults, and those with lung diseases.
