Based on long-term data of chemical and biological monitoring, the risk of anthropogenic impact on urban water bodies was estimated (Kazan, Republic of Tatarstan, Russia). These chemical parameters were used as pollution markers: dissolved oxygen, BOD, ammonium compounds, as well as pollutants, which exceeded MAC (15 ingredients in total). The main biological indicators were the total number of phytoplankton, the relative number of oligochaetes in the composition of zoobenthos and the relative number of rotifers in the zooplankton. It is shown that urban aquatic ecosystems are in transition from equilibrium to critical state according to the degree of risk of anthropogenic impact.
