Abstract
The article presents data on monitoring the ecological state of surface waters in the city of Nur-Sultan (Republic of Kazakhstan) on the example of the Yesil River, taking into account published data. The content of oxygen, anions and cations was studied in two sections of the Yesil River - at the exit from the Vyacheslav reservoir and in the city of NurSultan under the bridge on the Triathlon Park. Samples were analyzed during the year from April 2021 to April 2022. Samples were taken monthly. Anions and cations were analyzed by ion chromatography. A systematic excess of MPC standards for the content of sodium, sulfates and chlorides was established. The content of nitrates and ammonium does not exceed the MPC. The reason is the influence of both agriculture and the utility sector of the city of Nur-Sultan.
