Comprehensive tools encompassing the evaluation of chemical process emissions, treatment simulation, and environmental performance are yet to be developed. This abstract describes a further presentation on estimating releases of chemicals and their environmental impact evaluation when including the modeling of pollution control systems. Chemical releases may present unanticipated health risks that EPA and its Office of Pollution Prevention and Toxics must evaluate, as described in the Toxic Substances Control Act. The overall evaluation may involve risk assessment, including evaluations of chemical releases, exposures, and hazards. This work is to support TSCA risk evaluation by means of rapid estimation of industrial chemical releases and management scenarios.
