CHANGE OF ELEMENTAL COMPOSITION OF SOIL UPPER HORIZON UNDER THE INFLUENCE OF OIL AND GAS REFINING ENTERPRISES

Abstract

The relevance of the research is caused by the lack of data on the effects of many refineries and other man-made objects on adjacent soils for specific regions when the general geochemical specificity of industrial sectors is studied. The main aim of the research is to identify the specifics of the impact of the refineries and some other man-made objects on the soil by comparing the elemental composition with the data of conditionally background territory and the clarke. Objects of research are soils of the Tyumen Federal Reserve and the territories of the location of Antipinsky, Omsk, Achinsk, Pavlodar refinery, soils of the settlements of Tomsk region and the city of Tomsk, soils of the territory affected by the former Semipalatinsk test site. Methods: selection and preparation of test plots, selection and preparation of soils, determination of the elemental composition by instrumental neutron activation and atomic absorption methods, interpretation of results. Results. The authors have investigated the elemental composition of the upper soil horizon of the eastern part of the Tyumen Federal Reserve, the location of the Antipinsky, Omsk, Achinsk, Pavlodar refineries, areas of the location of enterprises of the city of Tomsk, the zone of influence of the former Semipalatinsk test site. As a result of comparison with the data for regional soils, the geochemical specificity of each technogenic region was revealed. The paper reflects the difference in the elemental composition of the soils adjacent to different refineries, which is determined both by the technical parameters of the enterprises themselves and by the environmental conditions of the territories of their location. Comparing the clarke and conditionally background territory, the level of pollution and the range of chemical elements characterized by a high content were established for the named territories. Using the Antipinsky oil refinery as the example, the authors studied spatial distribution of elements by distance and the cardinal points from a man-made object.
