Benzyl chloride Quickview (CASRN 100-44-7)

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
    • B2 (Probable human carcinogen - based on sufficient evidence of carcinogenicity in animals)
  • Weight-of-Evidence Narrative:
    • Based on inadequate human data and sufficient evidence of carcinogenicity in animals; namely significantly increased incidences of benign and malignant tumors at multiple sites in both sexes of mice and a significant increase in thyroid tumors in female rats. There was evidence of mutagenicity in a variety of test systems.
    • This may be a synopsis of the full weight-of-evidence narrative. See IRIS Summary.

Quantitative Estimate of Carcinogenic Risk from Oral Exposure

Oral Slope Factor(s)
Extrapolation Method
1.7 x10-1 per mg/kg-day Linearized multistage procedure, extra risk
Drinking Water Unit Risks
4.9x10-6 per µg/L
Risk Level
Concentration
E-4 (1 in 10,000) 2x101 µg/L
E-5 (1 in 100,000) 2 µg/L
E-6 (1 in 1,000,000) 2x10-1 µg/L
