Salt composition of the Ussuri river waters

The salt composition spatiotemporal variability in the Ussuri River and its main tributaries, from the Sungach River mouth to the village of Kazakevichevo, is studied by the authors. They have revealed the features of chemical composition dynamics of the waters showing an increase in carryover of salts from Lake Khanka by the Sungach River waters. The Sungach River waters are characterized by a high content of basic ions, and the Ussuri River left-bank water - by the highest content of salts. The chloride ion amount in the mouth of the Ussuri River in 2013-2016 appears to be 1.4 times higher than that in 2008-2012.
