Assessment of Ecological State of Water Bodies Using Integral Hydrobiological and Hydrochemical Indicators

Abstract

The paper considers the features of the joint use of hydrobiological and hydrochemical indicators to characterize the ecological state of water bodies. The comparison of effectiveness of the joint assessment of the state of aquatic ecosystems based on hydrobiological and hydrochemical indicators is carried out. In some cases, a discrepancy between the integral assessment characteristics was revealed. It is due to the fact that the comparison of data of the Roshydromet hydrochemical and hydrobiological monitoring is carried out at the same site not taking into account hydrological features of water bodies.
