...AIR QUALITY ALERT IN EFFECT UNTIL 11 PM EDT SUNDAY... The Maine Department of Environmental Protection's Bureau of Air Quality has issued an Air Quality Alert for particle pollution until 11 PM EDT Sunday. Smoke from wildfires in Canada will linger in the Northern region today into Sunday. Outside of the northern areas, air quality is moderate for particle pollution. The Maine Department of Environmental Protection recommends that individuals consider limiting strenuous outdoor physical activity to reduce the risk of adverse health effects. People who may be especially sensitive to the effects of elevated levels of pollutants include the very young, the elderly, those with pre-existing respiratory problems such as asthma, those with heart disease and anyone who is working hard outdoors. But if you experience symptoms such as shortness of breath, coughing, throat irritation or an uncomfortable sensation in your chest please consider limiting the intensity and duration of your outdoor activities. A toll free air quality hotline has been established so Maine residents can stay informed on the air quality situations. The toll free number is: 1-800-223-1196.
