The influence of ecochemical and ecotoxicological factors on the water of the Kisishkevi River

This study examines the ecochemical and ecotoxicological conditions of the Kisishkevi River's water. The research was conducted in compliance with normative documents. For chemical analysis, both qualitative chemical experiments and mobile water quality analyzers, adhering to international standards, were employed. The results were evaluated in accordance with Georgia's environmental protection regulations. Parameters such as pH, mineralization, and dissolved oxygen were found to be within the permissible concentration limits for surface water, remaining within acceptable norms. However, in two seasons of the year, biological consumption of oxygen exceeded the standard levels for unpolluted waters. Notably, an increase in NO3- (nitrate) pollution was observed, with organic pollution levels rising from 40.1 mg/l to 63.2 mg/l. To maintain the ecological health of small rivers like the Kisishkevi, regular water quality monitoring is recommended.
