Abstract
In August 2018, EPA finalized the IRIS Toxicological Review of Hexahydro-1,3,5-Trinitro-1,3,5-Triazine (RDX). The Toxicological Review was reviewed internally by EPA and by other federal agencies and White House Offices in May 2018. Consistent with the May 2009 IRIS assessment development process, all written comments on IRIS assessments submitted by other federal agencies and White House Offices are made publicly available. Accordingly, interagency comments and the interagency science discussion materials provided to other agencies, including the interagency review draft are posted on this site.Hexahydro-1,3,5-Trinitro-1,3,5-Triazine (RDX, or Royal Demolition eXplosive) is a military explosive with limited civilian uses. In the United States, RDX is produced at Army munitions plants; it is not produced commercially.
Impact/Purpose
EPA is undertaking an update of the Integrated Risk Information System (IRIS) health assessment for Hexahydro-1,3,5-Trinitro-1,3,5-Triazine (RDX). The outcome of this project is an updated Toxicological Review and IRIS Summary that will be entered into the IRIS database.Status
The RDX assessment has been loaded into the IRIS website and database.Citation
