5. Summary of Data Reported and Evaluation
5.1 Animal carcinogenicity data
In oral experiments in mice, insufficient details were available to
allow an evaluation to be made.
Two feeding studies in rats were reported. One was negative, although
the time when the tumours occurred in both treated and control groups
was not given; the other provided no details of pathological studies
and therefore cannot be evaluated.
5.2 Human carcinogenicity data
The epidemiological study carried out on occupationally exposed
workers does not allow any conclusions to be made concerning the
existence of an excess risk of developing cancer.
Subsequent evaluation: Suppl. 7 (1987) (p. 63: Group 3)
For definition of Groups, see Preamble Evaluation.
