Particulate Matter (PM) in New England

Particle pollution presents a serious air quality problem in New England. Particle pollution is produced by a wide variety of natural and manmade sources, including factories, power plants, trash incinerators, motor vehicles (especially diesel engines), construction activity, fires, and natural windblown dust. In the wintertime, a particular concern is fine particles released by smoke from fireplaces, wood stoves and outdoor burning. This smoke can accumulate, especially in low-lying areas, when a temperature inversion traps a layer of cold air near the ground.
