Popis: | The changes in the ecological state of the water of the Dnieper basin have been analyzed and the possible causes of this phenomenon and the possible ways to improve its ecological status have been identified. Methodology. The analysis was performed taking into account changes in the content of the normalized parameters: sums of anions; dissolved oxygen in water; biochemical oxygen consumption; phosphates, nitrites, nitrates, as well as ammonium. The assessment was carried out using a retrospective analysis of the monitoring data and environmental assessment of Ukraine's water resources by the State Water Resources Agency of Ukraine over the past 10 years. A retrospective analysis was conducted according to the data on the control of water intake on the Dnieper within the Basin Water Resources Management at 14 posts. The analysis was carried out taking into account the requirements of the State Standard of Ukraine 4808: 2007. Results. In the future, changing the ecological status of the surface waters of the Dnieper basin in the direction of its improvement cannot happen without the development and implementation of a reliable and effective model for predicting its ecological status. The solution to the complex problem of environmental rehabilitation of the Dnieper basin should be taken to a new level in accordance with fundamental changes in the nature management and economic development strategy of the country and only through the development of a national program of restoration of its ecological status. To date, the only possible solution to the problem of deterioration of the Dnieper's environmental status may be to create effective levers for managing the Basin Directorate, including by improving the methodological basis of its environmental monitoring system. Originality. The study is based on an integrated approach, which includes conducting a retrospective analysis of all available data in the State Agency for Water Resources of Ukraine, which takes into account the principles of biodiversity conservation, sustainable use of water resources, management and river basins, monitoring and evaluation of information on their status. Practical value. The results of the study can be used in the development and implementation of a reliable and effective model for predicting the ecological status of surface waters of the Dnieper basin.
