Abstract

The paper presents the results of researches on soil pollution by hydrocarbons and heavy metals in one of the urbanized territory of the Absheron peninsula, which has long been subject to the influence of oil industrial development. Laboratory analyses revealed high concentrations of oil products and such toxic metals as Pb, Cr, Cu, As and Zn in soil samples from various sites of the study area. It was found that oil pollution in the soils of anthropogenic destroyed territories reaches up to 1,5, and sometimes deeper profiles. The results of calculations of potential ecological risk index have shown that according to both individual and sum values, the territory can be characterized with low potential ecological risk from heavy metals (RI < 40). High percentage in the total ecological risk belonged to Pb, Hg, and As.

Keywords

soil pollution, hydrocarbons, heavy metals, ecological risk index, Absheron peninsula.
