5. Summary of Data Reported and Evaluation

5.1 Animal carcinogenicity data

3,3'-Dichlorobenzidine is carcinogenic in the rat following oral and subcutaneous administration and in the hamster after oral administration.

5.2 Human carcinogenicity data

No epidemiological data are available, but as 3,3'-dichlorobenzidine and benzidine may be made in the same plant, the possibility cannot be excluded that 3,3'-dichlorobenzidine has contributed to the incidence of bladder cancer attributed to benzidine.
