    Abstract:
    The in vitro induction of sister chromatid exchanges (SCEs) in Chinese hamster ovary (CHO) cells by the polycyclic hydrocarbons, 7,12-dimethylbena[a]anthracene and 3-methylcholanthrene and some of the related dihydrodiols was investigated. Increased numbers of SCEs were seen in the chromosomes of cells exposed to non-K-region dihydrodiols. The most active compounds were the 3,4-dihydrodiol of 7,12-dimethylbenza[a]anthracene and the 7,8- and 9,10-dihydrodiols of 3-methylcholanthrene: the parent hydrocarbons and their corresponding K-region dihydrodiols were relatively less active. The results are consistent with others that suggest that the metabolic activation of both hydrocarbons proceeds through the conversion of non-K-region dihydrodiols into vicinal diol-epoxides.
