IDEM is declaring another Air Quality Action Day for all of Indiana on Friday, as stagnant weather continues to trap smoke and debris from Canadian wildfires over the state.
The agency says that there is a danger of particulates in the air, causing breathing problems for vulnerable populations. The smoke carries microscopic dust, soot, and liquids that settles deep into the lungs and cannot be easily exhaled. People are particularly vulnerable after several days of exposure.
IDEM says you should reduce your time outdoors to reduce unhealthy exposures and avoid exercising near busy roads.
