5. Summary of Data Reported and Evaluation

5.1 Animal carcinogenicity data

1,1-Dimethylhydrazine (UDMH) is carcinogenic in mice after oral administration. The observation of a few liver tumours after high oral doses of UDMH occurring in rats after a long latent period does not allow a proper evaluation of the carcinogenic effect in this species.

5.2 Human carcinogenicity data

No epidemiological data are available to the Working Group.

Subsequent evaluation: Vol. 71 (1999)

For definition of Groups, see Preamble Evaluation.
