摘要

这项工作引起了人们对跨界卡拉巴尔塔河流域地表水受到钼(Mo)、铀(U)、锂(Li)等有害元素污染问题的关注。确定了两个地表水污染地区,根据有害元素的总含量,这些地区属于“严重受影响”的类别,可能对灌溉水的质量产生不利影响。在靠近卡拉-巴尔塔厂尾矿库的水体中,Mo的浓度为540.95µg/L。在紧邻国家边界的卡拉巴拉河河床,过量的U(29.40-59.01µg/L)和Li(28.80-59.20µg/L)进入地表水。这些有害元素很可能由于地下水污染的释放而出现在河水中。

Natural and anthropogenic mechanisms of the elemental composition formation of the waters in the transboundary Kyrgyzstan-Kazakhstan River Karabalta, Central Asia

The work draws attention to the problem of contamination of surface waters of the transboundary Karabalta river basin with molybdenum (Mo), uranium (U), lithium (Li) and other hazardous elements. Two areas of surface water contamination were identified, which, based on the total content of hazardous elements, fall into the “seriously affected” category and may have a negative impact on the quality of irrigation water. In the water bodies located closest to the tailing pool of the Kara-Balta plant, concentration of Mo was revealed at the level 540.95 µg/L. In the Karabala River bed, in direct vicinity with the state border, excess amounts of U (29.40–59.01 µg/L) and Li (28.80–59.20 µg/L) enter surface waters. The hazardous elements most likely present in the river waters due the release of contaminated groundwater.

期刊介绍: Environmental Earth Sciences is an international multidisciplinary journal concerned with all aspects of interaction between humans, natural resources, ecosystems, special climates or unique geographic zones, and the earth: Water and soil contamination caused by waste management and disposal practices Environmental problems associated with transportation by land, air, or water Geological processes that may impact biosystems or humans Man-made or naturally occurring geological or hydrological hazards Environmental problems associated with the recovery of materials from the earth Environmental problems caused by extraction of minerals, coal, and ores, as well as oil and gas, water and alternative energy sources Environmental impacts of exploration and recultivation – Environmental impacts of hazardous materials Management of environmental data and information in data banks and information systems Dissemination of knowledge on techniques, methods, approaches and experiences to improve and remediate the environment In pursuit of these topics, the geoscientific disciplines are invited to contribute their knowledge and experience. Major disciplines include: hydrogeology, hydrochemistry, geochemistry, geophysics, engineering geology, remediation science, natural resources management, environmental climatology and biota, environmental geography, soil science and geomicrobiology.
