Air quality advisory issued for Milwaukee

The Wisconsin Department of Natural Resources is issuing an Air Quality Advisory for Ozone (Orange) for Kenosha, Manitowoc, Milwaukee, Ozaukee, Racine and Sheboygan counties effective 4:28 pm on Tuesday, June 23, 2009 through 10:00 pm on Wednesday, June 24, 2009.

The advisory is being issued because of persistent elevated levels of ground level ozone. Ground level ozone is formed when pollution from power plants, factories and other industrial sources, vehicle exhaust, and volatile organic compounds chemically reacts with hot temperatures, high humidity and atmospheric stagnation.

The Air Quality Index is currently in the orange level, which is considered unhealthy for people in sensitive groups and others, including people who are not in sensitive groups but who are engaged in strenuous outside activities or exposed for prolonged periods of time. People in those sensitive groups include those with respiratory diseases, such as asthma, older adults, and active adults and children. When an orange advisory for ozone is issued, people in those groups are advised to reschedule or cut back on strenuous outside activities.

People with lung diseases such as asthma and bronchitis should pay attention to shortness of breath or respiratory symptoms like coughing, wheezing and discomfort when taking a breath, and consult with their physician if they have concerns or are experiencing symptoms. Ground level ozone can irritate the respiratory system, reduce lung function, aggravate asthma and chronic lung diseases, and, over time, cause permanent lung damage.
