The unambiguous determination of trace levels of benzo(a)pyrene (BaP) in complex matrices requires considerable chemical isolation and spectroscopic or chromatographic evidence to ensure freedom from interferences. Examination of BaP isolates prepared from petroleum substitutes by liquid-liquid partitioning and adsorption/partition column chromatography or by more extensive column chromatography alone indicates an unambiguous determination of BaP in the range of 10/sup -2/ to 10/sup 3/ ..mu..g/g with a precision of better than +-10%. Results obtained with such methodology may be used to evaluate and validate more rapid analytical procedures. 2 figures, 1 table.
