WOE Characterization Framework for WOE Characterization
Data are inadequate for an assessment of human carcinogenic potential Revised Draft Guidelines for Carcinogen Risk Assessment (US EPA, 1999)
Basis:
  • Under the draft revised guidelines for carcinogen risk assessment (U.S. EPA, 1999), EPA concludes the data are inadequate for an assessment of human carcinogenic potential of 2-methylnaphthalene. Based on the absence of data concerning the carcinogenic potential of 2-methylnaphthalene in humans and limited equivocal evidence in animals.
  • This may be a synopsis of the full weight-of-evidence narrative.
