Original Targeted Toxic Compounds for Point and Area Sources

The Southwest Lake Michigan Pilot Study and the Great Lakes Regional Air Toxics Emissions Inventory using data from 1993 targeted 49 compounds that were identified as significant contributors to the contamination of the Great Lakes. These compounds, and the programs or agencies that have targeted them, are listed in the following table.
