Risk-Screening Environmental Indicators (RSEI) Model

Risk-Screening Environmental Indicators (RSEI) Model

EPA's Risk-Screening Environmental Indicators (RSEI) model helps policy makers, researchers and communities explore data on releases of toxic substances from industrial 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 Scores can be used to help establish priorities for further investigation.
