Particulate Matter(PM) Air Monitoring

The Department operates an air-monitoring network for PM-10, sulfur dioxide, nitrous oxides, ozone, carbon monoxide, metals, sulfates, nitrates and toxic air pollutants. This network includes 18 continuous sites, 17 non-continuous sites and 1 special project air toxic monitoring site. These sites are disbursed throughout Cook County, including in the City of Chicago.

Continuous site data is pulled every 5 seconds and stored at the Department’s computer in Maywood. Daily average readings can be accessed by the public through recorded massages, which are translated to an Air Quality Index (AQI).

 You can call for the AQI Report to (708)865-6320.
