ABSTRACT

We studied the distribution of heavy metals, benzo(a)pyrene (BaP) and oil products in soils of industrial areas of the cities of Rostov-on-Don, Volgograd and Taganrog. By comparison with the regional background, geochemical associations, characteristic of various types of industrial landscapes and determined by the specifics of production, were identified. It was established that main pollutants of soils of Rostov-on-Don and Taganrog are zinc, lead, copper and oil products; concentrations of mercury, arsenic, nickel do not reach sanitary and hygienic standards. The soil cover in the influence area of an oil refinery in Volgograd is contaminated with benzo(a)pyrene. Among the heavy metals, the maximum danger coefficient is characteristic of zinc and is 4.5. The content of oil products and benzo(a) pyrene exceeded MPC by 11.8 and 30.7 times. The soil pollution of industrial landscapes, mostly, is assessed as acceptable, in rare cases as moderately hazardous and dangerous. The anthropogenic factor, found from the assigning land use zones, appears to exert the greatest effect on the spatial patterns of pollutants distribution.

Keywords: heavy metals, industrial urban landscapes, sources of pollution, geochemical associations, total pollution index.
