The paper presents an analysis of the content of PAHs and total petroleum hydrocarbons in the urban soil of the Kazan city (Russia). The soil was sampled in the areas of vehicles and industrial impact. There was no exceeding of standards neither by the sum of PAHs not by the individual compounds. Compounds with high-molecular-weight, which indicates a pyrolytic origin of their intake from air aerosols during fuel combustion, made the main contribution to the sum of PAHs content. The relative uniformity of the PAHs content in the soil was determined with the exception of the area with a high traffic activity, where the excess of the standards were 3.2 and 96 times for the sum of PAHs and benzo(a)pyrene respectively. The average content of total petroleum hydrocarbons did not exceed the regional standards in urban soil.
