Inadequate information to assess carcinogenic potential Guidelines for Carcinogen Risk Assessment (U.S. EPA, 2005)
Basis:
  • Under the Guidelines for Carcinogen Risk Assessment (U.S. EPA, 2005a), the database for thallium and compounds provides "inadequate information to assess carcinogenic potential."
  • This may be a synopsis of the full weight-of-evidence narrative.
