Reaction of benzo(a)pyrene-7,8-dihydrodiol-9,10-epoxide with human hemoglobin and chromatographic resolution of the covalent adducts
The formation of hemoglobin-carcinogen adducts has been proposed as a measure of human exposure to carcinogens. Hemoglobin-carcinogen adducts have been detected in carcinogen-treated animals and in human populations. Although polycyclic aromatic hydrocarbons (PAH) are ubiquitous in the human environment and DNA-PAH adducts have been detected in human tissues, the occurrent of hemoglobin-PAH adducts in humans has not been described. In this study we examined the effects of reaction conditions on the extent of in vitro reaction of human hemoglobin and (+)(anti)-({sup 3}H)benzo(a)pyrene-7,8-diol-9,10-epoxide (BPDE), a metabolite largely responsible for the carcinogenic effect of benzo(a)pyrene. The chromatographic properties of the resulting hemoglobin-BPDE adducts were examined by conventional DEAE-cellulose ion-exchange liquid chromatography and by reversed-phase high-performance liquid chromatography. Several adducts were chromatographically resolved from hemoglobin and from the individual globins.
