For the second day in a row, air pollution levels in the Chicago metropolitan area are expected to be in the "orange" category, which means air is "unhealthy for sensitive groups," according to a news release from the Illinois Partners for Clean Air and the Illinois Environmental Protection Agency.
The agencies have declared Tuesday and today as Air Pollution Action Day, as current weather conditions and data shows ozone levels will be elevated today.
Those with respiratory disorders, such as asthma, as well as children and adults, are considered more sensitive populations. Those groups should take precautions and follow their doctor-prescribed regimen.
Residents and businesses can help reduce air pollution by taking public transit, sharing rides, walking or biking; avoid idling the car if driving; run errands after 7 p.m. when sunlight is not as strong; use energy-efficient light bulbs; and do not burn leaves or other yard waste, according to the release.
