Environmental protection and maintaining the ecological balance are the most important state development priorities. Environmental policy issues are closely related to the level of technological equipment of economic sectors, sustainable development of territories, social policy and are aimed at ensuring environmental safety. The expansion of the geography of oil and gas production in Russian Federation in the direction of the northern and Far Eastern territories, the development of new territories (Eastern Siberia, the Arctic, the Far East) determine increased requirements for the environmental component of the extraction, processing and transportation of raw materials. At the same time, comprehensive interdisciplinary studies of anthropogenic changes in natural ecosystems under the influence of oil and gas production are practically not carried out. A unique feature of the Yamal-Nenets Autonomous Okrug (YNAO) is the coexistence of two opposite areas of economic activity in a vulnerable and extreme Arctic environment: the development of rich reserves of mineral resources and traditional nature management of the indigenous peoples of the North. The district has become a center of gas and oil production, intensive industrial development of the territory has led to the formation of significant foci of pollution and environmental degradation in recent years. An urgent task is the geo-ecological monitoring of the state of the environment of the regions of oil and gas production in the YNAO.
The purpose of this work is to detect changes in the chemical composition of the waters in the lakes on the territory of Pur-Tazovsky district of YNAO with the beginning of industrial operation of the oil and gas condensate deposit. This article provides the chemical composition of the surface waters of the Gydan Peninsula, Parisento lake area. Physicochemical parameters and chemical components were discussed: pH, Eh, conductivity, major ions, and trace elements. The regularities of change surface waters composition depending on the genesis of reservoirs and the passage of time were determined. During research in 2016-2018, it was found that with the beginning of industrial operation of the East Messoyakhsky oil and gas condensate field there was a slight increase in mineralization and pH values in the water bodies of the Tasovsky district. The changes affected the main anion-cationic composition, where there was an increase in the percentage of sodium and chlorine. Similar transformations of the chemical composition of water bodies are possible under the action of alkaline and chlorine-containing process solutions used in the development and operation of wells. |
