The latter assessed the pollution of water objects in the Russian Arctic
The main sources of water pollution in 2019 in the Arctic steel enterprises in Norilsk, Monchegorsk and Nickel, oil and gas facilities in the North of European Russia and Western Siberia, pulp and paper mills in Arkhangelsk region and gold mining enterprises of Yakutia, according to a review of the status and environmental pollution in the Russian Federation in 2019, published by Roshydromet.
As specified in the review, a significant contribution to the pollution of surface waters making a compound of Nickel, manganese, copper, molybdenum, iron, dithiophosphate Krasilovka and mercury. Also in 2019 compared to the previous year, the cases of surface water contamination by compounds of manganese (46%), copper (47%), Nickel (29%), and iron compounds decreased by 24%.
According to the Roshydromet, in 2019 in the Arctic zone of the Krasnoyarsk region was recorded eight cases of extremely high pollution in two water bodies and 15 cases of high pollution in four water bodies that much greater than 2014-2018, when checked in single cases. All reported cases of water pollution associated with the work of the Norilsk mining and metallurgical Kombinat, the mining and processing copper-Nickel ore. Priority pollutants a small water facilities within the urban district of Norilsk are: copper ions (157 MPC), Nickel (63,3 MAC), cadmium (of 9.6 MPC) and petroleum products (174,4 MPC).
The survey notes that for 2014-2019 the majority of the incidents of severe pollution in the continental Arctic zone of the Russian Federation is registered on the water bodies of the Murmansk region. In 2019 in the Murmansk oblast had registered 113 cases of high and 63 cases of extremely high contamination, which is almost 33% more than last year's values. Characteristic indicators of surface water pollution in the Murmansk region are the compounds of copper, Nickel, aluminum, manganese and mercury.
According to Roshydromet, the main sources of water pollution in Arkhangelsk oblast are enterprises of pulp and paper, forestry, wood processing and mining industry, enterprises of power engineering and transport, including river and sea, housing facilities.
The greatest negative impact on water bodies of the Yamalo-Nenets Autonomous Okrug (AO) is connected with the enterprises of gas, oil and petrochemical industries, and the utilities of the cities of Novy Urengoy, Gubkino, the Purovsk and Nadym. Overall, the water bodies of the Yamalo-Nenets Autonomous Okrug contaminated by compounds of manganese, iron, copper, zinc and oil products.
