[Arctic: Ecology and Economy], 2024, vol. 14, no. 4, pp. 549-561. DOI: 10.25283/2223-4594-2024-4-549-561. (In Russian).
Abstract:
The article analyzes the results of studying technogenic hydrochemical dispersion flows arising during the development of ore and placer tin deposits in the Arctic regions of the North-East of Yakutia. Most of the large tin deposits are located beyond the Arctic Circle: primary (Deputatskoye, Dyakhtardakhskoye, Kester, Ulakhan-Egelyakhskoye, Churpunnya, Ege-Khaya) and placer (Smolnikova, Tasappa, Tirekhtyakh, Chokurdakhskaya) deposits. Development of tin deposits leads to a sharp change in the chemical composition of natural waters and the formation of extensive technogenic hydrochemical flows that negatively affect ecosystems. Pollution of natural waters during the development of tin deposits is associated with abnormal concentrations of mineral suspensions, sulfates, hydrogen, iron, aluminum, manganese, copper, zinc, lead, arsenic, and mercury.
