Methodology for Evaluating Potential Carcinogenicity in Support of Reportable Quantity Adjustments Pursuant to CERCLA Section 102

摘要

The Agency's Human Health Assessment Group (HHAG) has developed a methodology for ranking CERCLA hazardous substances for the purpose of establishing reportable quantities (RQs) based on the primary criteria of potential carcinogenicity. The methodology combines the weight of evidence and potency factor to determine a hazard ranking of high, medium, or low which corresponds to an RQ of 1, 10, or 100 pounds, respectively. An appendix is included which lists 194 compounds that were evaluated for potential carcinogenicity along with their respective weight-of-evidence categories, potency factors, and hazard rankings. Profiles for each of these 194 chemicals are available as separate documents.
