Smoke from ongoing wildfires in Canada has severely impacted air quality in large parts of the United States, particularly in northern regions such as Minnesota, Wisconsin, and Iowa, leading to health advisories. As of Tuesday, over 200 active wildfires are burning across Canada, with many considered out of control, according to the Canadian Interagency Forest Fire Centre. The U.S. National Weather Service has advised sensitive groups, including children and the elderly, to limit outdoor activities due to poor air quality caused by the smoke, which can cause respiratory issues and worsen pre-existing health conditions, according to CBS News and ABC News.

In particular, real-time air quality data indicated that parts of Minnesota were experiencing air quality levels categorized as “very unhealthy” with indices exceeding 200. Minneapolis reported some of the worst air quality in the world, ranking among the top cities for air pollution, according to The New York Times and Reuters.

The smoke has also impacted other regions, with air quality alerts stretching into the Northeast and down the East Coast. According to meteorologists, the smoke from the fires has created hazardous air pollution levels that could be felt even as far as New York and New England. Experts stress that everyone can experience negative health effects from wildfire smoke exposure, regardless of previous health status, highlighting the importance of preparing for smoke-related health issues, as noted by Los Angeles Times and Al Jazeera.

Authorities in various states are recommending the use of air purifiers indoors and are advising residents to stay indoors as much as possible while the smoke lingers. This estimation follows warnings from health officials regarding potential long-term adverse effects linked to fine particles contained in the smoke, which can infiltrate the lungs and bloodstream, according to ABC News and India Times.
