ABSTRACT
The aim of the current work was to study the main tendencies in the accumulation and distribution of benzo[a]pyrene in soils of the affected zone of the Novocherkassk regional power plant. Studies were conducted on the soils of monitoring plots subjected to Novocherkassk regional power plant emissions. The tendencies in the distribution and accumulation of benzo[a]pyrene in the studied soils coincided during the 4 years of monitoring studies. It has been found the 5-km zone to the northwest from the power station, which coincides with the predominant wind direction, is most subjected to contamination by benzo[a]pyrene, with the maximum accumulation at a distance of about 1.6 km from the source. Dynamics of pollutant accumulation in soils depends on number of Novocherkassk power station emissions. The content of benzo[a]pyrene in the soil is an indicator of the technogenic load impact on the areas, for which the combustion products of hydrocarbon fuel are the major pollutants. Gradual increase in the pollutant content in soils of the studied territory was established for 4 years period of supervision up to 16 maximum permissible concentrations at the most polluted monitoring plot. It was explained by considerable increasing of volumes of polluting substances emission by the enterprise.

Keywords: soil, benzo[a]pyrene, subcritical water extraction, monitoring, thermal power station
