Hydrocarbons are extracted from samples by alkaline digestion, and interfering materials are removed by adsorption onto Florisil, partitioning of the sample between isooctane and dimethyl sulfoxide, and column chromatography on Sephadex LH-20. A radioactive internal standard is used to correct for losses during procedures. Twenty polycyclic aromatic hydrocarbons are determined by reversed-phase high-pressure liquid chromatography, utilizing simultaneous detection by untraviolet absorbance and fluorescence monitors. 2 figures.
