Еxpedition studies were conducted in order to take samples in the components of elementary landscapes - precipitation (snow), surface waters, roadside dust, soil, bottom sediments and sediments at the water's edge along the route of Shakhty (Eastern Donbass) – Margaritovo village (coast of Taganrog Bay) in the Rostov region. In the selected samples, the mass concentration of oil products (OP) was determined, the analysis of which showed that road dust and snow are one of the sources of soil pollution, surface water and bottom sediments. The following sequence of oil product content levels has been revealed as they decrease: road dust → soil → sediments at the water's edge → bottom sediments → snow → surface water, which persists at almost all but one station. The content of oil products in the soils of the region should be estimated as varying from acceptable to average, while the surface waters contained this pollutant in concentrations below the MPC for the waters of fish farms.

The geographical location, tectonic and geological-hydrogeological structure of the Maly Liman Lake basin, its landscape features as a natural monument of regional significance located on the area of the Abraus Peninsula of the Krasnodar Territory were described. The results of current bathymetry studies of the lake were shown. The hypothesis about tectonic origin of its hollow was justified. The sedimentations of the Maly Liman and Abrau lakes were tested and their description was fulfilled. By using radionuclide analysis the sedimentation rates were determined. Expedition work was carried out and a description of the outlets of the perched waters was made. The water balance development models of the of the Maly Liman Lake in the conditions of arid and relatively full-water period were constructed. The perched water dynamics of the upper reaches and surface run-off as the dominant supply sources of the lake was described. A hydrogeological section was constructed along the section of Lake Abrau – Lake Maly Liman. The existence of their hydraulic connection was proved, as well as the presence of two aquifers – the perched water and groundwater.
