Evaluation of Soil Toxicity of an Oil and Gas Condensate Field after Reclamation of Disturbed Lands on the Example of the Field of the Yamal-Nenets Autonomous District

Abstract

Oil pollution is both a hazard in terms of scale and toxicity. Oil and oil products cause poisoning, death of organisms and soil degradation. The natural self-purification of natural objects from pollution depends on the natural conditions of the region, the presence of moisture, heat and the activity of the vital activity of the soil biocenosis. In the conditions of Siberia, where a low temperature regime is maintained for a long time, the self-purification process is a long process. As a result of the long industrial use of the Medvezhye oil and gas condensate field, the soils of this area have accumulated pollutants. As a result, it is required to assess the toxicity of the soil, as well as to provide ways and methods to prevent its environmental pollution. One of the ways to restore disturbed landscapes is technical and biological reclamation, the features and results of which are considered in this study using the Medvezhye deposit sand pit as an example.
