The samples were taken from different locations in the Bor town and its surroundings and analyzed using gas chromatographic-mass spectrometric method, and hierarchical cluster analysis with the average linkage between groups as an appropriate statistical method. The obtained results soundly illustrated the distribution of individual PAHs in soil and simultaneously, they indicated probable PAH sources, i.e., anthropogenic or natural. In accordance with the obtained hierarchical dendrogram, it can be supposed that only benzo(a)pyrene had a natural origin (from different processes in the soil), whereas all other PAHs had anthropogenic, i.e. atmospheric origin. The grouping of the latest compounds showed that they were kept in soil for different - longer or a shorter time.enHCAdistributionsoil PAHsconferenceObject
