The combination of sunshine and hot, humid air has led the Michigan Dept. of Environmental Quality (MDEQ) to issue an Air Quality Action Day for southeast Michigan on Saturday.

The statement, issued Friday afternoon, added that some relief is on the way. "A stronger cold front should pass through the region Saturday night and clean out the air statewide for several days," MDEQ representative Jim Haywood wrote.  

People and businesses should avoid these activities on Air Action days:

• Refueling vehicles or topping off when refueling
• Using gasoline-powered lawn equipment
• Using charcoal lighting fluid

Everyone is encouraged to car pool, use their bicycles or walk, and delay or combine errands when possible. Active children and adults, and persons with respiratory diseases such as asthma, should limit prolonged outdoor exertion, the MDEQ advises.
