The Air Quality Division (AQD) has recently completed development of an
air toxics monitoring strategy for Michigan.  This effort arose due to
the need for such a strategy identified by the AQD, Michigan
Environmental Science Board, Southeast Michigan Council of Governments,
and the Michigan Relative Risk Task Force.  Additionally, the need for
high quality air toxics monitoring data has also been identified as a
concern at the federal level.

The strategy developed by the AQD addresses a number of objectives that
include such things as determination of long-term trends, elucidation of
spatial gradients, support of receptor and dispersion models, population
exposures, and environmental indicators.

The strategy includes a proposed ambient monitoring network that
addresses air toxics of concern from direct inhalation, as well as an
atmospheric deposition network that focuses on persistent
bioaccumualtive toxics.  The ambient network will consist of 35 sites
and take five years to become fully deployed.  Substances to be
monitored include volatile organic compounds, carbonyl compounds, trace
metals, and polynuclear aromatic hydrocarbons.  The atmospheric
deposition network will monitor levels of mercury, PCBs, and dioxins and
furans.  The number of sites for this network will range from 3 - 9,
depending on the particular compound being monitored.

Currently funding is not available to implement this strategy.  It is
anticipated that as funding becomes available, the strategy will be used
as a guide to help implement an expanded air toxics monitoring program.

Further information is available in the report, The Development of an
Air Toxics Monitoring Strategy for Michigan, June 25, 2002. This report
is available on the Department of Environmental Quality's website at

Announcements.
