RSEI informs communities about the potential chronic health risks from industrial releases.
The Risk-Screening Environmental Indicators (RSEI) is a computer-based screening tool developed by EPA that analyzes risk factors to put Toxics Release Inventory (TRI) release data into a chronic health context. RSEI is often used by researchers, environmental/nonprofit organizations, and government agencies to:
- Examine trends.
- Identify important emissions situations for follow-up.
- Support community-based projects.
- Initially screen potential impacts of emissions.
