a screening-level tool from pounds-based, hazard-based, and risk-related perspectives
To assess and compare the hazard or potential impact of industrial chemical release from each facilities in the world, we use US EPA’s Risk-Screening Environmental Indicators (RSEI) methodology (v.2.3.4). The reason why we use RSEI is because
- This model provides important hazard-based and risk-related perspectives regarding the impacts of TRI releases on chronic human health. The model quickly organizes and evaluates complex data.
- And this methodology allows for greatly increased speed in performing screening analyses, thereby conserving resources for conducting more precise, site-specific risk evaluations.
- In addition, its use as a priority-setting tool allows resources to be focused in areas that will provide the greatest potential risk reduction.
This adaptable method can model any chemical if toxicity characteristics, appropriate physicochemical properties, release levels and release location are known or can be estimated. Moreover, it considers both cancer and non-cancer chronic human health endpoints.
