Inventory provides updated look at Great Lakes toxic air emissions

Ann Arbor, Mich. -- The latest iteration of the Great Lakes Regional Air 
Toxic Emissions Inventory, a key resource for environmental management in 
the binational region, has been released by the Great Lakes Commission.

The inventory organizes annual data collected by the eight Great Lakes 
states and province of Ontario into a standardized and accessible format. 
The largest multijurisdictional project of its kind in North America, it 
targets 213 separate chemical compounds, including all those classified as 
hazardous air pollutants by the U.S. Environmental Protection Agency.

“This inventory is a valuable tool for research and decisionmaking on air 
quality issues in the binational Great Lakes region,” said Dr. Michael J. 
Donahue, president/CEO of the Great Lakes Commission. “It provides a solid 
base of information to guide policy decisions and lawmaking, and assists 
our scientists in understanding the life cycles of these toxins and how 
they behave. We’re fortunate to have the participation of our Great Lakes 
states and the province of Ontario in compiling this information.”

The latest inventory is based on data collected in 2001, updating the 
previous 1999 inventory, the last year for which complete data was 
available. Data for more recent years is now being compiled.

Listing pollutants by type, quantity and source, the inventory categorizes 
emissions by more than 600 industrial classifications and more than 2,000 
types of sources. Sources include point sources, such as industrial 
facilities; mobile sources, including on- and off-road; and area sources, 
such as airborne residue from pesticide applications or dispersed small 
sources such as residential wood stoves.

Vehicle emissions are a major source of organic compounds, including 
toluene, benzene and xylene, which are among the most abundant pollutants 
by weight. Point sources are the dominant contributor of the 14 metal 
compounds covered by the inventory, as well as many nonmetals. Area source 
emissions were the major source of 14 of the 16 polycyclic aromatic 
hydrocarbons (PAHs) inventoried, as well as 34 other nonmetal compounds.

The emissions data assist researchers in modeling the transport of the 
contaminants through the atmosphere, their deposition to the water and air 
surfaces of the region, and eventual outcomes, that include decay, burial, 
accumulation in fish and wildlife, and exposure to humans. Understanding 
these processes is important to forming regional, national and 
international emission reduction policies to protect the Great Lakes and 
their human, wildlife and aquatic inhabitants.

The inventory also helps identify inconsistencies in data collection and 
analysis across jurisdictions, and encourages the establishment of standard 
procedures and protocols. Funding is provided by the U.S. Environmental 
Protection Agency (U.S. EPA).

The inventory is part of a suite of air quality projects the Commission is 
pursuing. Others include development of an online portal to provide 
researchers and the public with easier access to emissions data, and 
management of U.S. EPA’s Great Lakes Air Deposition Program (GLAD), which 
provides grants for innovative air quality research projects.
