WOE Characterization Framework for WOE Characterization
Inadequate information to assess carcinogenic potential Guidelines for Carcinogen Risk Assessment (US EPA, 2005)
Basis:
  • Under the Guidelines for Carcinogen Risk Assessment (U.S. EPA, 2005a), there is "inadequate information to assess the carcinogenic potential" of urea.
  • This may be a synopsis of the full weight-of-evidence narrative.
