Minnesota Pollution Control Agency

The Minnesota Pollution Control Agency (MPCA) has issued an air pollution health advisory for Rochester and the Twin Cities metropolitan area for Monday and Tuesday, Nov. 23 and 24. Air pollution monitors across much of the upper Midwest indicate elevated levels of fine particle pollution with Air Quality Index (AQI) values in the high moderate range. Fine particle levels are expected to continue to increase as a result of foggy conditions which enhance particle formation and light winds which limit particle dispersion. On Monday, air quality conditions in the Twin Cities and Rochester are expected to reach 97 on the AQI, which is just below the level considered Unhealthy for Sensitive Groups. Conditions are expected to remain high moderate on Tuesday, with the potential for some areas to experience pollution levels considered Unhealthy for Sensitive Groups. Good AQI levels are expected Wednesday and Thursday (Thanksgiving), as clean, dry air from the north moves into the region. Those who have respiratory or cardiovascular problems, young children, the elderly, and persons who are physically active are considered sensitive to elevated levels or air pollution. These individuals may need to postpone or reduce vigorous activity. Fine particles can be drawn deeply into the lungs, so reduce activities that lead to deep or accelerated breathing. Exposure to high levels of fine particles may cause individuals to experience chest pain, shortness of breath, coughing or fatigue. If you experience these symptoms, contact your physician. Even individuals who are otherwise healthy may experience health effects when air pollution levels increase. Motor vehicle emissions are a significant contributor to fine particle pollution. For improved air quality, residents are encouraged to reduce their impact by avoiding idling, carpooling, combining trips, and using alternative means of transportation such as biking, walking and mass transit. During poor air quality events, residents should avoid burning wood and reduce their energy consumption.
