...AIR QUALITY ALERT IN EFFECT UNTIL MIDNIGHT EDT WEDNESDAY NIGHT...

The Maine Department of Environmental Protection`s Bureau of Air
Quality has issued an Air Quality Alert for particle pollution until
midnight EDT Wednesday night.

Particle pollution levels are expected to rise into the Unhealthy
for Sensitive Groups range on Tuesday. Values are already in the USG

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.
