title: Carcinogen-DNA adducts in human alveolar macrophages.
abstract: The occurrence of 7 beta,8 alpha-dihydroxy-(9 alpha,10 alpha)-epoxy-7,8,9,10- tetrahydrobenzo(a)pyrene (BPDE-)-DNA adducts was investigated by synchronous fluorescence spectrophotometry in human pulmonary alveolar macrophages (PAM) collected by bronchoalveolar lavage. In preliminary assays BPDE-DNA adducts were consistently detected in PAM of smokers, whereas samples from nonsmokers did not exhibit specific peaks.
