Air Quality Alert issued June 17 at 9:32AM EDT by NWS Caribou ME
The Maine Department of Environmental Protection's Bureau of Air Quality has issued an Air Quality Alert for particle pollution until 11 PM EDT this evening. Particle pollution levels have been in the Unhealthy range on Wednesday. If visibility is poor and the smell of smoke is strong, follow this health message: people with heart or lung disease, older adults, those who work outdoors, teenagers and children should avoid prolonged or heavy exertion and consider moving activities indoors or rescheduling. Everyone else should reduce prolonged or heavy exertion. Take more breaks during all outdoor activities. 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, older adults, those who work outdoors, those with pre-existing respiratory problems such as asthma, and those with heart disease. It is okay to be active 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. Additionally the Maine Department of Environmental Protection has the air quality forecast available on the web at www.maine.gov/dep/air/aqforecast.
