Abstract
Ortho-toluidine carcinogenicity has been tested in chronic experiments using mice, rats and dogs. Tumors were induced in 19% of mice (lung and kidney adenomas, leukemia), rats--40% (subcutaneous fat tumors, mammary fibroadenomas, leukemia, renal tumors and hepatic sarcoma). Bladder tumors developed in two dogs after 9 and 10 years of experiment. Both literature and experimental evidence point to o-toluidine as a hazard to humans.
