TRI Webinar - “Estimation of Community Exposure to Toxic Releases: A Perspective from the Geography of Public Health”

Dillard University Deep South Center for Environmental Justice (DU/DSCEJ) and the U.S. Environmental Protection Agency (EPA) will host the Toxics Release Inventory (TRI) Summer Webinar:

Date: Wednesday, September 24, 2014
Time: 11:00 am – 12:30 pm central


When analyzing the impacts of toxic releases upon public health, a critical question is identifying the extent to which communities are exposed to toxic releases. In most situations, this must be estimated, because it is impractical and, frequently, unethical to track individuals to measure personal exposure histories. Additionally, public health data are often disseminated at an aggregated spatial scale, such as county by county. To effectively relate these aggregated health data to toxic releases, the impact of toxic releases must also be estimated at the same scale, rather than for each individual person. Therefore, there needs to be an efficient means of relating the toxic releases reported by individual factories and other users of toxic chemicals in the United States Environmental Protection Agency’s Toxics Release Inventory (TRI) Program to county-level public health data.

Dr. Conley’s webinar discusses ways of developing these estimates of a community’s exposure to toxic releases within the context of the presenter’s broad-scale public health research. He will present research involving both airborne and waterborne releases, and their impacts on lung cancer and kidney disease respectively. Advantages and disadvantages of different estimation methods will be presented. The presenter’s open access research articles on the estimation of impacts from toxic releases can be found at (airborne releases) and (waterborne releases).


Dr. Jamison Conley is an Associate Professor of Geography at West Virginia University.  He has a BA in Geography & Computer Science from Gustavus Adolphus College, and an MS and PhD in Geography from Pennsylvania State University.  His research interests include the application of spatial analytical techniques to a variety of research areas, including public health, crime patterns, international development, and specialty coffees.
