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