Creosote Quickview (CASRN 8001-58-9)

Health assessment information on a chemical substance is included in IRIS only after a comprehensive review of toxicity data by U.S. EPA health scientists from several Program Offices, Regional Offices, and the Office of Research and Development.

Disclaimer: This QuickView represents a snapshot of key information. We suggest that you read the IRIS Summary to put this information into complete context.

For definitions of terms in the IRIS Web site, refer to the IRIS Glossary.

Carcinogenicity Assessment for Lifetime Exposure
  • Weight-of-Evidence Characterization
    • B1 (Probable human carcinogen - based on limited evidence of carcinogenicity in humans)
  • Weight-of-Evidence Narrative:
    • Limited evidence of the association between occupational creosote contact and subsequent tumor formation, sufficient evidence of local and distant tumor formation after dermal application to mice, and some evidence of mutagenic activity, as well as the well-documented carcinogenicity of other coal tar products to humans.
    • This may be a synopsis of the full weight-of-evidence narrative. See IRIS Summary.
