Unprecedented air quality event continues across all of Minnesota, air quality alert due to wildfire smoke in effect through Tuesday, Aug. 3 The Minnesota Pollution Control Agency (MPCA) has issued an air quality alert for all of Minnesota. This is an unprecedented significant air quality event for Minnesota, extending over many days. The alert takes effect Friday, July 30, beginning at 12 p.m. and runs until Tuesday, August 3, at 12 p.m. The affected area includes all of Minnesota, and the tribal nations of Grand Portage, Fond du Lac, Upper Sioux, Leech Lake, Red Lake, Mille Lacs, and Prairie Island. Smoke from Canadian wildfires lingers over most of Minnesota. There will be some slight improvement in air quality throughout Friday and Friday night. However, on Saturday northerly winds behind a cold front will bring more smoke from wildfires located north of the Canadian border in Ontario and Manitoba into Minnesota. This reinforcing batch of heavy smoke is expected to arrive starting Saturday morning. Smoke will continue pouring into the state throughout Saturday and into Sunday. High pressure will build over the area for Sunday and remain over the area for Monday into Tuesday morning. Smoke will recirculate under the high pressure, leading to prolonged period of heavy smoke. Fine particle levels will begin to improve Tuesday as southerly winds start moving the smoke out of the state. People whose health is affected by unhealthy air quality: There are people who are more likely to be affected when ozone pollution reaches an unhealthy level. People who have asthma or other breathing conditions like chronic obstructive pulmonary disease (COPD), chronic bronchitis, and emphysema. Children and teenagers. People of all ages who are doing extended or heavy, physical activity like playing sports or working outdoors. Some healthy people who are more sensitive to ozone even though they have none of the risk factors. There may be a genetic base for this increased sensitivity. Health effects: Unhealthy ozone levels can aggravate lung diseases like asthma, emphysema, and COPD. When the air quality is unhealthy, people with these conditions may experience symptoms like difficulty breathing deeply, shortness of breath, throat soreness, wheezing, coughing, or unusual fatigue. If you are experiencing any of these symptoms, use your inhalers as directed and contact your health care provider. Take precautions: Everyone should take precautions when the air quality is unhealthy. Take it easy and listen to your body. Limit, change, or postpone your physical activity. If possible, stay away from local sources of air pollution like busy roads and wood fires. If you have asthma, or other breathing conditions like COPD, make sure you have your relief/rescue inhaler with you. People with asthma should review and follow guidance in their written asthma action plan. Make an appointment to see your health provider if you don't have an asthma action plan.  Pollution reduction tips: Ozone is produced on hot, sunny days by a chemical reaction between volatile organic compounds and oxides of nitrogen. Reduce vehicle trips and fill-up the gas tank at dawn or dusk. Encourage use of public transport, or carpool, when possible. Postpone use of gasoline powered lawn and garden equipment on air alert days. Use battery or manual equipment instead. Avoid backyard fires.
