An algorithm was developed for the determination of polycyclic aromatic compounds in soils: optimal conditions were found for the extraction and separation of the polycyclic aromatic hydrocarbon (PAH) fraction from soil samples. The distribution of PAHs in the profile of peaty-podzolic-gleyic soil was determined using fluorometry and chromato-mass-spectrometry. It was found that both low- and high-molecular PAHs occur in organic horizons and that lighter PAHs are predominant in mineral soil horizons.
