Abstract

Data were obtained on changes in the content of certain metals, oil, and oil products in the soil cover of an oil and gas field in Krasnoyarsk krai. In the period from 2015 to 2020, the content of Pb increased by 3 times in the upper layer and 5 times in the lower layer; the content of Zn increased by 2 times in the upper layer; the content of Mn increased by 5 times in the upper layer and 20 times in the lower layer; the content of Cr increased by more than 2 times; the content of Fe increased by 2.5 times in the upper layer; and the content of Ni increased by 7 times in the upper layer, and that of oil and oil products, by 10 times in the upper layer and 25 times in the lower layer. The studied species of soil animals, springtails, showed their nonviability in the conditions under consideration. Evidence of this was a significant reduction in biodiversity and, most importantly, the number of soil animals. The obtained data can be used in modeling the processes of soil degradation in areas with similar climatic conditions due to the impact of the oil and gas industry on the terrestrial ecosystem. This is the first time that research has been conducted in this area.
