本文论述了贝加尔湖东岸乌斯季-塞伦加洼地大气降水、土壤和地下沃茨形成的一些具体特征，塞伦加河三角洲形成于此，为贝加尔湖提供了约50%的水量。结果表明，在近地表条件下，在活跃的水交换区，在该区域内形成了还原环境，在那里观察到高浓度的有机质，铵，铁，锰，硝酸盐，锌，镉的沃茨。这些组分在凹陷地下沃茨中的高含量与自然和人为过程的发生有关。据发现，乌斯季-塞伦加洼地的自然水文地质系统受到了与从其边界排放数十至数百公里的工业废物的越境大气运输有关的负面影响。
This paper addresses some specific features of the formation of atmospheric precipitation and soil and ground waters in the Ust’-Selenga depression on the eastern coast of Lake Baikal, where the delta of the Selenga River supplying about 50% of water into the lake has been formed. It was shown that a reducing environment was formed within this region under near-surface conditions in the zone of active water exchange, where waters with high concentrations of organic matter, ammonium, iron, manganese, nitrate, zinc, and cadmium were observed. The high contents of these components in the ground waters of the depression are related to the occurrence of both natural and anthropogenic processes. It was found that the natural hydrogeologic systems of the Ust’-Selenga depression are affected by a negative impact related to the transboundary atmospheric transport of industrial wastes discharged tens to hundreds of kilometers from its boundaries.
