FAQ: I would like to make calculations for chemical "X", but it is not in the chemical database. What are the chemical properties for that chemical and how do I add it to the database?

For various reasons, we do not typically grant user requests for chemical information. However, the following link to the US EPA IRIS database may help you out:


The instructions for customizing the chemical database are on pages 16-17 of the RBCA Tool Kit manual, or on pages 19-20 of the RBCA Tool Kit for TRRP manual.
