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.
