BaP is metabolized in mammalian systems by the mixed function oxidase system of liver microsomes. This system catalyzes the oxidation of BaP via epoxide intermediate to phenol, diol and quinone metabolites. One of these 7,8-dihydroxy-9,10-epoxy-7,8,9,10-tetrahydro-BaP is thought to act as the ultimate carcinogen by binding covalently to cellular DNA. It is also known that Cunninghamella elegans oxidized BaP to its phenol, diol and quinone metabolites. In addition, the alcohols were detected as glucuronide and sulfate conjugates. These metabolites are remarkably similar to those observed in higher organisms. On the other hand, some investigators have demonstrated that plants take up BaP and anthracene from soil or culture medium containing these compounds. This paper reports the finding that soybeans grown in BaP polluted soil take it up and metabolize to its phenol, diol and the glucuronide and sulfate conjugates of the alcohols.
