Abstract
Two petroleum crude oils were distilled into two sets of fractions patterned after the boiling ranges of crude coal-derived liquids, including a heavy oil/heavy distillate (bp > 232 °C 450 °F) and a high-boiling vacuum gas oil (bp > 343 °C 650 °F). Samples of these distillates and two naturally occurring, undistilled, high-boiling, petroleum-derived crude oils were analysed for selected four- to six-ring polycyclic aromatic hydrocarbon (PAH) dermal tumorigens. The PAH were isolated using semipreparative-scale high performance liquid chromatography, and quantitated using gas chromatography-mass spectrometry in the single-ion monitoring mode. The isomer distributions of these PAH in petroleum- and crude coal-derived samples exhibiting similar boiling ranges were different, and the concentrations of the PAH were one to two orders of magnitude greater in the coal-derived liquids. Their distributions and concentrations in the petroleum-derived samples were more like those in hydrogenated coal liquids than those in the crude coal liquids.
