Hexachlorobenzene (HCB) is an important environmental contaminant derived mainly from industrial and agricultural sources. It is carcinogenic in mice, rats and hamsters. It has now been studied in a medium-term bioassay for carcinogenicity based on the induction of preneoplastic lesions in the liver. We report here that the bioassay can rapidly detect carcinogenic doses of HCB and that there is a clear dose-response relationship. At the lowest dose of HCB administered, the incidence of preneoplastic lesions in the liver was no different from that in controls.
