Minnesota Air Quality Declines: What You Need to Know
30 Apr
Summary
- Twin Cities rank 39th for particle pollution and 57th for ozone.
- Wildfire smoke and ozone contribute to unhealthy air.
- Duluth and Arrowhead areas remain clean for particle pollution.
The American Lung Association's annual "State of the Air" report highlights a concerning decline in air quality for Minnesota. The Twin Cities metro area is now ranked 39th nationally for short-term particle pollution and 57th for ozone pollution, both of which can cause lung irritation.
Factors contributing to this trend include increased ozone formation on hot, sunny days and significant wildfire smoke events experienced across the country. These pollutants are small enough to enter the bloodstream, potentially impacting heart and brain health.
Despite the overall negative trend, Duluth and the Arrowhead region stand out, recognized on the top 25 cleanest list for year-round particle pollution at number 18. As wildfire season approaches, experts recommend preparing clean indoor air spaces and using N95 masks outdoors on smoky days.
