What is the Detroit Exposure and Aerosol Research Study?
The Detroit Exposure and Aerosol Research Study (DEARS) is part of U.S. Environmental Protection Agency’s (EPA) ongoing research on how people are exposed to fine particles and air toxics and the conditions that affect their exposures. Its purpose is to develop scientific information that helps EPA understand how air pollutant concentrations measured at outdoor community air monitoring stations compare to those measured in various neighborhoods and in some residences. The DEARS includes a major field data collection effort, conducted in Wayne County, Michigan, that occurred from 2004 through 2007 and ongoing data analyses.
