Chloroethane (CE; CAS No. 75-00-3) is mutagenic in four tester strains of Salmonella typhimurium, plus and minus S9 activating fraction. Male rats responded with basal cell carcinomas, keratoacanthomas, squamous cell carcinomas, and trichoepitheliomas. Female rats showed brain astrocytomas at an incidence of 3/50 (6%) vs 0/50 (0%) controls vs 1/297 (0.3%) in historical controls. Female mice responded with malignant and metastasizing endo- and myo-metrial cancers. They spread to the lung, ovary, lymph nodes, kidney, adrenal gland, pancreas, mesentery, urinary bladder, spleen, and heart. The SAR, positive mutagenicity, and an exceptional degree and severity of carcinogenicity all indicate that CE causes cancer in rodents and is probably carcinogenic to similarly exposed humans.
