CHICAGO – The Illinois EPA has declared that an Air Pollution Action Day will be in effect tonight and through tomorrow, Tuesday July 25. This problem is due to elevated levels of particulate matter from persistent wildfire smoke from Canada impacting the region. The resulting p09oor air quality is considered unhealthy, particularly for sensitive groups.

We encourage limited prolonged activity for those with chronic respiratory issues and recommend children, teens, seniors, people with heart or lung disease, and individuals who are pregnant avoid strenuous activities and limit their time outdoors. Residents can also take individual action to reduce pollution levels, like carpooling or using public transportation. 

For additional precautions, all Chicagoans may also consider wearing masks, limiting their outdoor exposure, moving activities indoors, running air purifiers, and closing windows. As these unsafe conditions continue, the City will continue to provide updates and take swift action to ensure that vulnerable individuals have the resources they need to protect themselves and their families. 

Anyone who needs immediate medical attention should dial 911. We will closely monitor any worsening air conditions and will provide updated guidance as needed. For real-time air quality updates visit airnow.gov.
