A comprehensive study of the Gruzsky Elanchik River ecosystem, utilizing biochemical indicators of saprobity, has revealed a complex and heterogeneous picture of its condition. On one hand, the river exhibits signs of resilience, demonstrated by sufficient levels of dissolved oxygen and a diverse range of benthic organisms in certain areas. Conversely, the analysis results point to a clear anthropogenic impact, evidenced by elevated levels of organic matter and the prevalence of saprobiont species – indicators of pollution. An imbalance in the composition of phyto- and zooplankton, as well as exceeding permissible concentrations of nitrogen and phosphorus, indicate localized problems associated with pollution and eutrophication. The dominance of euglenoid algae in the phytoplankton is a clear signal of a high level of organic pollution, requiring close attention. Therefore, the ecosystem of the Gruzsky Elanchik River is in a state of dynamic equilibrium, experiencing both the positive influence of natural factors and the negative impact of anthropogenic pressure.

Keywords:Gruzsky Elanchik, saprobiological analysis, biological and hydrochemical methods, anthropogenic impact
