1,2-Dichloroethane Quickview (CASRN 107-06-2)

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 the induction of several tumor types in rats and mice treated by gavage and lung papillomas in mice after topical application
    • 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
9.1 x10-2 per mg/kg-day Linearized multistage procedure with time-to-death analysis, extra risk
Drinking Water Unit Risks
2.6x10-6 per µg/L
Risk Level
Concentration
E-4 (1 in 10,000) 4x101 µg/L
E-5 (1 in 100,000) 4 µg/L
E-6 (1 in 1,000,000) 4x10-1 µg/L

Quantitative Estimate of Carcinogenic Risk from Inhalation Exposure

Inhalation Unit Risk(s)
Extrapolation Method
2.6 x10-5 per µg/m3 Linearized multistage procedure, extra risk

Inhalation Concentrations at Specified Risk Levels

Risk Level
Concentration
E-4 (1 in 10,000) 4 µg/m3
E-5 (1 in 100,000) 4x10-1 µg/m3
