The formation of trans-dihydrodiols from dibenz[a,c]anthracene, dibenz[a,h]anthracene and chrysene by chemical oxidation in an ascorbic acid-ferrous sulphate-EDTA system and by rat-liver microsomal fractions has been studied using a combination of thin-layer (TLC) and high pressure liquid chromatography (HPLC) to separate the mixtures of isomeric dihydrodiols. The 1,2- and 3,4-dihydrodiols of dibenz[a,c]anthracene, the 1,2-, 3,4- and 5,6-dihydrodiols of dibenz[a,h]anthracene and the 1,2-, 3,4- and 5,6-dihydrodiols of chrysene were formed in chemical oxidations. These dihydrodiols were also formed when the three parent hydrocarbons were metabolized by rat-liver microsomal fractions and, in addition, dibenz[a,c]anthracene yielded the 10,11-dihydrodiol. The 1,2- and 3,4-dihydrodiols of dibenz[a,c]anthracene have not been reported previously either as metabolites of the hydrocarbon or as products of chemical syntheses and the 5,6-dihydrodiol of chrysene was not detected in earlier metabolic studies.
