Feasibility of Using GEMS (Graphical Exposure Modeling System) to Perform Risk Assessments Using SARA (Superfund Amendment and Reauthorization Act of 1986), Toxic Release Inventory Information

摘要

Under Title III, Section 313 of the Superfund Amendment and Reauthorization Act of 1986 (SARA) companies which release toxic chemicals into the environment are required to report annually the amount of these toxic releases. Because the chemical toxic release reports are public information, EPA Region V is concerned that the raw data published in the toxic chemical release reports will be misinterpreted and will in turn generate unfounded public concern. The study examines the possibility of using the Graphical Exposure Modeling System (GEMS), a computer program, to transform incoming raw data into better qualified, user ready, public information. Specifically, the report analyzes the compatibility between the raw data reported in the toxic chemical release reports and the input requirements of the GEMS exposure model. An industrial site in East St. Louis, Illinois is used as a test site for the development of the exposure assessment. The study discusses the research and the methods used to perform the exposure assessment. The report also reviews the legislation which requires companies to report toxic release data, the basics of exposure assessment and the GEMS model, the research methods used, and the findings of the study.
