The state of Minnesota is entering another in a long string of summer days marred by air quality alerts. Poor air quality will continue through Saturday with lingering wildfire smoke from Canada.

Data suggests that air quality in Minneapolis ranked worse than the air in Egypt, South Korea and China. Minneapolis has the fifth worst air quality in the world, according to an air quality monitoring platform that reported its latest findings Saturday.

The MPCA says that sensitive groups should avoid prolonged or heavy exertion, and everyone should limit their time spent outdoors.
