Аннотация: This article presents the results of a study of the biological diversity of hydrobionts in the watercourses of the Upper Amur basin, located in the zone of influence of the mining facility of the Bystrinsky mining company (BMC). The Upper Amur Basin is historically a mining region. In addition to the functioning of the BMC, other mПоказать полностьюining companies also produce ore and placer gold in this basin. The main studies of the impact of mining on the aquatic ecosystems of the Upper Amur basin are related to the study of the transboundary Argun River. The purpose of the work is to study the biological diversity of hydrobionts of watercourses of the Upper Amur basin, using the example of the Gazimur River, in the zone of the possible negative impact of BMC facilities. Currently, the hydrogeochemical anomaly of the mining area is a factor enriching the hydrochemical state of the aquatic environment. The high migration capacity of Al, As, Sr, Cu, Mn, Zn, Fe, and V in the river waters under consideration allows them to accumulate to concentrations exceeding the MPC, regardless of the degree of exposure to the BMC. Hydrobiological studies of the Gazimur River and its tributaries have shown that hydrobionts are represented by widespread species of Siberia and the Far East. Seasonal and interannual variations of biota are associated with changes in climatic, hydrochemical, and hydrological indicators. One reason for the low species richness and extremely low number of aquatic organisms near the BMC (the Taina and Bystraya rivers) may be the high turbidity of river water. Based on the results, indicator species of hydrobionts are identified for the subsequent monitoring of the effects of mining on aquatic ecosystems.
