MPCA issues air pollution advisory for today!

The Minnesota Pollution Control Agency (MPCA) has issued an air pollution health advisory for portions of eastern, southern and southwestern Minnesota, effective 10am Saturday through 9pm Saturday. The affected area includes the Twin Cities Metro, Mankato, New Ulm, Albert Lea, Fairmont and Marshall.

Forecasted temperatures in the low 90s, clear sunny skies, and light and variable winds will lead to the formation of ground level ozone. As a result, the Air Quality Index (AQI) is forecasted to reach into the 90s on Saturday, which is just below air quality conditions considered unhealthy for sensitive groups. Ozone concentrations will be the lowest in the morning hours before gradually rising late morning through the afternoon. Ozone concentrations will begin to decline after sunset Saturday.

At-risk Populations: Ozone pollution is expected to be near a level considered unhealthy for sensitive groups. Those sensitive to ozone include people with preexisting respiratory or cardiovascular conditions, the elderly, children, and individuals who participate in outdoor activities requiring extended or heavy exertion. These individuals are encouraged to postpone or reduce vigorous outdoor activity, or schedule outdoor activity in the morning, when ozone levels are lower. Even persons who are otherwise healthy may experience health effects when ozone levels increase. 

Health Impacts: Elevated levels of ozone have been linked to respiratory and cardiovascular health effects. Exposure to high levels of ozone may exacerbate preexisting health conditions. High ozone levels may make it more difficult to breathe deeply and vigorously, cause shortness of breath and breathing discomfort, and result in coughing and a sore or scratchy throat. If you experience these symptoms, contact your physician. 

Pollution-reduction Tips: Ozone is produced on hot, sunny days by a chemical reaction between volatile organic compounds and oxides of nitrogen. These pollutants are released from motor vehicles, lawn and garden equipment, paints and solvents, refueling stations, and other activities that require fuel combustion. Conserving energy; buying clean, renewable power; and utilizing alternative means of transportation, such as mass transit, will all reduce your contribution to air pollution. During air quality alerts, residents are particularly encouraged to use public transportation, car pool or reduce vehicle trips and engine idling. Postpone the use of gasoline-powered equipment and avoid burning wood.
