The Michigan Department of Environmental Quality today released the 2005 Annual Air Quality Report, summarizing air contaminant data and providing information on air improvement trends. The DEQ measures levels of six common air pollutants at air monitors scattered throughout the state: particulate matter, ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead, in addition to monitoring pollution levels for numerous other toxic air contaminants.

The report shows that the air pollution levels continued to decline in 2005 due to a reduction in pollutant emissions from a variety of sources. Emission reductions from vehicles, fuels, power plants, and manufacturers, as well as the choices made by all of Michigan’s citizens at their homes, all play an important role which contributes towards a healthier environment in which to work and play.

As a result of these successful efforts, the DEQ applied to the U.S. Environmental Protection Agency for a change in air quality status for 16 counties that now meet the federal air standards for ozone.

For more information on air quality where you live, visit the DEQ “AIR” Web page at www.michigan.gov/deqair. The 2005 Annual Air Quality Report is available in “Air Publications” under Spotlight.
