ABSTRACT
A benzo[a]pyrene(BP)-Gua adduct was extracted in the urine of rats treated with BP. Some (0.15%) of the administered dose of BP was excreted as BP-Gua within 48 h. A double labelling experiment demonstrated that the excreted product contained both a BP and a Gua moiety. Partially hepatectomized rats treated with [14C]Gua during the regenerative phase were injected with [3H]BP and the urine collected and processed by chromatographic procedures. The adduct had similar chromatographic properties to the adduct released from human PLC/5 cells treated with 7,8-dihydroxy-9,10-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene (BPDE) and co-chromatographed with 7-BPDE-Gua released from BPDE-adducted DNA under aqueous conditions. Detection and quantitation of BP-Gua offers an alternative, non-invasive method of monitoring individuals exposed to carcinogenic polycyclic aromatic hydrocarbons (PAHs).
