гидрохимические показатели

The main object of the article is to show indicator functions of small water bodies (streams, ponds) for 4 rural areas in agricultural landscapes (Belgorod region). In the course of the study the groups of anthropogenic objects with their special impacts are identified and ranked. The correlation between concentrations of chemical forms of biogenic elements (N, P) demonstrates the contribution of typical problems of agricultural landscapes in ecological situation (rural areas) as well as contribution of adjacent urban areas.

The article presents the results of laboratory investigation of water samples collected in the summer of 2016 on the rivers of the Soviet district of the Saratov region. A brief analysis of the hydrochemical indicators is given from the point of view of their effect on the water quality of the examined rivers. Based on the results of the analysis, the relevant conclusions were drawn. At some points of sampling, exceeding the values of maximum permissible concentrations for a number of indicators was detected.
