PM 2.5 Information and Documents

Contact:  Air Quality Division 517-373-7023
Agency: Environmental Quality


Fine particulate matter (PM 2.5) is tiny liquid or solid particles with a diameter less then 2.5 micrometers.  PM 2.5 is composed mainly of ammonium sulfate, ammonium nitrate, organic carbon and smaller portions from elemental carbon and soil or crustal elements.  PM 2.5 comes from a variety of sources included burning, fugitive dust, and biogenic sources (from plants).  PM 2.5 can be emitted directly (primary) or react in the air to form particles (secondary).  Respiratory and cardiac problems are directly linked to PM 2.5 exposure.  Children, older adults and people with heart or lung diseases are especially susceptible to the health effects from PM 2.5.

Currently, seven counties in Southeast Michigan around Detroit are not attaining the annual standard.  The daily PM 2.5 standards were recently updated and EPA is in the process of designating nonattainment areas.
