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.
As EPA combines the hazard characterizations with exposure and risk characterizations to develop risk-based prioritizations, each hazard characterization will be removed from EPA's HPV Hazard Characterizations Web page.
