Tobacco and its combustion products contain several known or potential human carcinogens and studies are not beginning to emerge for detecting DNA and protein adducts in tobacco users. A highly sensitive (32)P-adduct assay, capable of measuring a wide spectra of aromatic and/or hydrophobic DNA adducts, was used to evaluate tobacco use-related adducts in human oral mucosal cells. The chromatographic behavior of the oral mucosal DNA adducts by selective PE1-cellulose TLC and their extractability in 1-butanol suggest that they have an aromatic and/or hydrophobic moiety and two of the major adducts have been tentatively assigned as aromatic amine derivatives.
