Intra-Annual Dynamics of the Chemical Composition of Water at the Mouth of the Baksan River

The article presents the results of a study of the intra-annual dynamics of the chemical composition of water at the mouth of the Baksan River in 2023. The intra-annual dynamics of transparency, pH, mineralization, hardness, permanganate oxidizability, content of macrocomponents (bicarbonates, chlorides, sulfates, nitrites, nitrates) and iron compounds were studied. According to average annual values, the water of the studied object has average hardness and belongs to the hydrocarbonate, fresh waters of rivers of average mineralization. An excess of the maximum permissible concentration for sulfates, nitrates and iron compounds was detected. It is shown that the hydrochemical regime of the studied water body is interconnected with level and thermal regimes and is influenced by anthropogenic factors. The data obtained are necessary to identify patterns of distribution of substances in natural geosystems located in the Malka River basin, of which the Baksan River is a first-order tributary.
