Health and Environmental Effects Profile for 3,3'-Dimethylbenzidine

Report Information

The Health and Environmental Effects Profile for 3,3'-Dimethylbenzidine was prepared to support listings of hazardous constituents of a wide range of waste streams under section 3301 of the Resource Conservation and Recovery Act (RCRA) and to provide health-related limits for emergency actions under Section 101 of the Comprehensive Environmental Response, Compensation and Liability ACt (CERCLA). Both published literature and information obtained from Agency program office files were evaluated as they pertained to potential human health, aquatic life and environmental effects of hazardous waste constituents. 3,3'-Dimethylbenzidine has been evaluated as a carcinogen. The human carcinogen potency factor (q1*) for 3,3'-dimethylbenzidine is 9.2 (mg/kg/day) for oral exposure. Existing data are insufficient to determine an RQ value.
