SPATIO-TEMPORAL ANALYSIS OF THE ECOLOGICAL STATE OF THE DNIESTER RIVER TRANSBOUNDARY WATER

Abstract

The ecological state of transboundary water of the Dniester River Basin was analyzed in the context of cross-border cooperation. The major objects of economic activity affecting the state of transboundary water were identified in the Dniester River Basin in Ukraine and Republic of Moldova. It was established that over the years of transboundary cooperation, a decrease in the average annual concentrations of Suspended solids, Nitrites, Chlorides and Sulfates below the maximum permissible values was achieved. The ecological state of the Dniester River transboundary water in time and space was investigated using an integral assessment of the state of the Dniester River water environment. It is recommended to assess the transboundary water ecological state using complex indices. An assessment of the ecological reliability of the Dniester River Basin transboundary water in 2020 was carried out. The research results show that the use of transboundary water of the Dniester River Basin is potentially dangerous. Further cooperation between Ukraine and the Republic of Moldova in the issue of reducing the wastewater containing harmful substances with a synergistic effect, is encouraged.
