Hazard Characterizations
This Web page describes and enables you to link to hazard characterizations, developed by EPA based on screening-level hazard (toxicity) data submitted to or otherwise available to the Agency on high-production volume chemicals.
Development of these hazard characterizations is EPA's initial step to use data collected as part of the High Production Volume Challenge Program in the Agency's efforts to protect human health and the environment from potential harm posed by existing chemicals.
During 2008 and early 2009, EPA combined some hazard characterizations with exposure characterizations to develop risk-based prioritizations (RBPs). For those chemicals, the link will take you to the RBP, which includes the complete hazard characterization in an appendix.
What's New
On September 29, 2009, EPA posted hazard characterizations on 100 additional high production volume (HPV) chemicals to the web.
