Chem. Abstr. Name: Diphenyldiazene

5. Summary of Data Reported and Evaluation

5.1 Animal carcinogenicity data

Azobenzene was tested by the oral route in mice and by the subcutaneous route in mice and rats. In the oral study in mice it produced an excess of liver-cell tumours over the controls in males but not in females in one of the two strains used. Subcutaneous studies in mice and rats were negative, but they cannot be evaluated because the adequacy of the dose used could not be assessed.

5.2 Human carcinogenicity data

No case reports or epidemiological studies were available to the Working Group.

Subsequent evaluation: Suppl. 7 (1987) (p. 58: Group 3)

For definition of Groups, see Preamble Evaluation.
