5. Summary of Data Reported and Evaluation
5.1 Animal carcinogenicity data
Purified o-tolidine is a systemic carcinogen in the rat when given

significance because of the small number of animals involved. In
feeding experiments, the commercial product failed to produce tumours
5.2 Human carcinogenicity data
No epidemiological studies are available.
Subsequent evaluation: Suppl. 7 (1987) (p. 62: Group 2B)
