The commercial mixture of polychlorinated biphenyls (Sovol) studied by biochemical and immunochemical methods was found to be an inducer of a wide range of cytochrome P-450 isoenzymes. The induced enzymes activated in the Ames test a series of procarcinogens differing both in structure and in target organs: benz(a)pyrene, 3-methylcholanthrene, nitrosomorpholine, dimethylnitrosamine, aflatoxin B1, orthoaminoazotoluene, 2-acetylaminofluorene, cyclophosphamide and benzidine. According to the parameters the studied Sovol is similar to Aroclor 1254 and may be recommended to be used as an inducer of microsomal enzymes in routine tests for carcinogen screening.
