The Current State of Water Quality in the Styr River Within Rivne Region

Abstract

The work is devoted to the study of the current state of water quality in the Styr river. The main causes of water pollution within the Volyn Upland and Volyn Polissya in the territory of Rivne region were investigated. The main pollutants and pollutant agents of the river water were identified. The detailed analysis of the dynamics of changes, the ecological assessment of the current state of the water quality of the Styr river were carried out. Characteristics of water quality are based on the ecological classification of the quality of surface waters of land and estuaries of Ukraine, which includes a wide range of hydrophysical, hydrochemical, hydrobiological indicators that reflect the peculiarities of the abiotic and biotic components of aquatic ecosystems. The studies have shown that the water of the Styr river in the Volyn Upland is much cleaner than in Volyn Polissya, the integral ecological index of the mean values is 2,2 and 2,5, and the maximum values are 2,5 and 3,0, respectively.
