Predictive Models and Tools for Assessing Chemicals under the Toxic Substances Control Act (TSCA)

EPA has developed assessment methods, databases, and predictive tools to help evaluate what happens to chemicals when they are used and released to the environment and how workers, citizens, and the environment might be exposed to and affected by them.  These tools may be helpful when laboratory studies or monitoring data are not available or need to be supplemented.

• Use EPA's hazard models
• Use EPA's exposure and fate models
