The thick haze caused by smoke from more than 100 Canadian wildfires is causing unhealthy air quality conditions across a large part of Minnesota. That compares to just 13 in Rochester.
The Minnesota Pollution Control Agency has issued an air pollution health alert for the northern two-thirds of Minnesota. At the “unhealthy” air level, anyone may be affected and members of sensitive groups – including children, the elderly and people with respiratory problems – may feel serious health effects.
Air quality is expected to remain poor due to fine particles until midday Sunday. The expanded area includes the Twin Cities, where the acrid odor of smoke hung in the air Monday afternoon. Even individuals who are otherwise healthy may experience health effects when pollution levels increase.

Pollution-reduction tips: Fine particles are produced from combustion activities, which include fossil fuel-based energy generation, motor vehicle exhaust, gasoline-powered yard and lawn equipment, and wood burning.
