Aldicarb Quickview (CASRN 116-06-3)

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.

Chronic Health Hazard Assessments for Noncarcinogenic Effects

Reference Dose for Chronic Oral Exposure (RfD)

Critical Effect
Point of Departure*
Sweating as clinical sign of AChe inhibition NOAEL : 1 x10-2 mg/kg-day 10 1 x10-3 mg/kg-day

* The Point of Departure listed serves as a basis from which the Oral RfD was derived. See Discussion of Conversion Factors and Assumptions for more details.

Carcinogenicity Assessment for Lifetime Exposure
  • Weight-of-Evidence Characterization
    • D (Not classifiable as to human carcinogenicity)
  • Weight-of-Evidence Narrative:
    • Aldicarb was not found to induce statistically significant increases in tumor incidence in mice or rats in feeding studies or mice in a skin painting study. In the feeding studies there were, however, significant trends in pituitary tumors in female rats and fibrosarcomas in the male mouse. This evidence, together with the fact that less than maximum tolerated doses were used, indicates that the available assays are inadequate to assess the carcinogenic potential of aldicarb.
    • This may be a synopsis of the full weight-of-evidence narrative. See IRIS Summary.
