Abstract
The authors analyzed water quality in manmade water bodies at the used and operating tungsten, molybdenum and complex ore mines in eastern and southwestern Transbaikal. The chemical analysis of water used atomic absorption spectrometry and inductively coupled plasma mass spectrometry. The standardized cumulative pollution index is calculated. It is found that the level of the environmental hazard of the test water bodies is abnormally high, which points at the environmental emergency and ecological catastrophe. The greatest threat to surface and underground water is made by the manmade water bodies at the Pervomaiskoe, Sherlova Gora, Bukuka and Bom-Gorkhon deposits. The recreational utilization of such water by people is unhealthy and inadmissible.
