* WHAT...The Minnesota Pollution Control Agency has issued an Air Quality Alert for ozone pollution. The Air Quality Index (AQI) is expected to reach the Orange or Unhealthy for Sensitive Groups category. * WHERE...East central and central Minnesota. * WHEN...From noon CDT to 9 PM CDT Tuesday. * IMPACTS...Sensitive groups, such as people with lung disease (including asthma), heart disease, children and older adults, and people who are active outdoors, may experience health effects. * ADDITIONAL DETAILS...Ground-level ozone is expected to be high on Tuesday afternoon in the Twin Cities metro area and central Minnesota. Mostly sunny skies, warm temperatures, and low humidity will provide a favorable environment for two types of pollutants (volatile organic compounds and nitrogen oxides) to react with sunlight in the air to produce ground-level ozone. Ozone is expected to reach unhealthy levels during the afternoon and will subside in the early evening.
Sensitive groups, such as people with lung disease (including asthma), heart disease, children and older adults, and people who are active outdoors, should limit prolonged or heavy outdoor exertion. Reduce or eliminate activities that contribute to air pollution, such as outdoor burning, and use of residential wood burning devices. Reduce vehicle trips and vehicle idling as much as possible.
