Аннотация
The Aydar–Arnasay lake system is located in a natural depression in the southern part of the Kyzylkum Desert,southwest of the Shardara Reservoir. It is a system of endorheic (closed) lakes that receive water from the collector–drainage network and the Shardara Reservoir. Over the past 50 years, the lake system has accumulated 2.5 times morewater than all 53 regional reservoirs combined. Studies conducted on the concentrations of major pollutants in the Aydar–Arnasay lake system revealed significant exceedances of almost all parameters. The most pronounced factor is the totalmineralization of water, which exceeds established standards by more than 25 times, thereby affecting the system’sbiodiversity and overall ecological stability.
