Cook County Air Pollution Monitoring - Ozone

Cook County tracks and measures several air pollutants through an air monitoring network situated throughout the County.  One measured pollutant, ozone, can have serious health implications including shortness of breath, coughing, wheezing, eye and nose irritation. It can be especially dangerous to the elderly, children, people with chronic respiratory ailments (especially asthma), and even individuals who exercise outdoors.  For more information on ozone, its effects, and ways you can help reduce pollutant levels, click here.
