Fast‐atom bombardment mass spectrometry has been used to obtain spectra of conjugated benzo( a )pyrene (bap) metabolites using a 1:1, glycerol+thioglycerol matrix. bap Glucuronides give positive‐and negative‐ion spectra with peaks due to [M + H] + and [M − H] − ions and a Major fragment peak (base peak) at [bapOH] + and [bapO] − . bap Sulfates (sodium salts) give similar negative‐ion spectra with [M − Na] − and [bapO] − peaks, but the positive‐ion spectra are dominated by sodium and glycerol adducts of the bap sulfates.
