INDIANAPOLIS – The Indiana Department of Environmental Management has issued an Air Quality Action Day in the Unhealthy Air Quality Index range, forecasting high levels of fine particles (PM2.5) in the air for today for central Indiana, including Columbus.
A state map including regions and affected counties is available at SmogWatch.IN.gov.
Current air monitor readings across the state are rising as the Canadian wildfire plume moves from north to south. Forecast models are all pointing toward very high levels for today.
PM2.5 is composed of microscopic dust, soot, and liquid that settles deep into the lungs and cannot be easily exhaled. Those people at risk are particularly vulnerable after several days of high PM2.5 exposure. Everyone should reduce or avoid exertion and heavy work outdoors during these conditions.
