D (Not classifiable as to human carcinogenicity) Guidelines for Carcinogen Risk Assessment (U.S. EPA, 1986)
Carcinogenic potential cannot be determined Proposed Guidelines for Carcinogen Risk Assessment (U.S. EPA, 1996)
Basis:
  • Under the proposed Guidelines for Carcinogen Risk Assessment (U.S. EPA, 1996), it is concluded that the carcinogenic potential of cumene cannot be determined because no adequate data, such as well-conducted long-term animal studies or reliable human epidemiological studies, are available for any assessment.
  • This may be a synopsis of the full weight-of-evidence narrative.
