Abstract DNA-carcinogen adducts offer a potential dosimeter for environmental genotoxicants reaching the exposed individual. Because the target tissues for many chemical carcinogens are not readily accessible for monitoring adducts in humans, peripheral blood lymphocytes (PBLs) have served as surrogate sources of exposed DNA. Both benzo(a)pyrene (B(a)P) and benzo(b)fluoranthene (B(b)F) are widely distributed in the environment as components of complex mixtures, such as automobile exhaust, cigarette smoke, foods, water, and urban air. Thus, human exposure to these chemicals is widespread, and they probably contribute to overall human lung cancer risk. The interpretation of the results of such studies would be enhanced by an understanding of the pharmacokinetics of specific DNA adduct formation and persistence in both target and surrogate tissues.
