Risk-Screening Environmental Indicators (RSEI) Model
Webinar: "Introduction to the RSEI Model"
Join EPA on September 21 to learn how the RSEI model can help you identify chemicals, facilities, industry sectors, and locations with the greatest potential for chronic human health impacts.

EPA's Risk-Screening Environmental Indicators (RSEI) model helps policy makers, researchers, and communities explore data on releases of toxic substances from industrial and federal facilities. RSEI incorporates information from the Toxics Release Inventory (TRI) on the amount of toxic chemicals released, together with factors such as the chemical’s fate and transport through the environment, each chemical’s relative toxicity, and potential human exposure. RSEI model results can be used to help establish priorities for further investigation and to look at changes in potential human health impacts over time.
