Annotation Chemical research results of natural water samples composition taken from soda lakes of Eastern Transbaikalia are presented; thermodynamic calculations were carried out using the MINTEQ software package, taking into account the presence of humic and fulvic acids in lake wa-ters; and basic forms of some metals available were determined. Dependence of organically and inorganically bound metal complexes formation on mineralization and pH is determined; metals sorption selectivity by humic substances and authigenic minerals formation in soda lakes are demonstrated, and lake waters saturation indices with respect to these minerals are given. The number of metals bound to complexes and their positions in the rows are determined by the level of organic matter, their properties, together with basic geochemical parameters of the environment.
Key words Key words: Eastern Transbaikalia; thermodynamic modeling; soda lakes; humic substances; sorp-tion
