Fall scene in MaineAir Toxics Program

The Air Toxics Program is specifically dedicated to the collection and dissemination of data about air toxics in Maine.  Air toxics refers to a very broad group of air pollutants that, in sufficient concentration, could cause serious health effects to people breathing air that contains them. In order to help protect the health of Maine residents and preserve our environment, the Department of Environmental Protection has developed this web site to help enlighten Maine's public as to the hazards associated with air toxics.
