Particulate Matter (PM10) Data Map

Particulate matter with a mean diameter of 10 microns or less is emitted from transportation and industrial sources. Exposure to particle pollution is linked to a variety of significant health problems ranging from aggravated asthma to premature death in people with heart and lung disease.

IDEM operates four continuous PM10 monitoring sites that are polled hourly in order to obtain the most current information. This continuous data is available interactively on the map and the table below. The intermittent monitoring sites measure PM10 over a 24 hour period based on a six-day sampling schedule. A summary of PM10 data is available under the Quick View Current Monitoring Data Summaries.
