Bioindication of Gomel, Bryansk and Chernihiv regions transboundary of rivers
Species composition of macrozoobenthos for 58 stations of 44 transboundary Belarus-Russia-Ukraine rivers was determined. It is shown that the values of the Extended Biotic Index has high values and correspond to the first and second class of water quality. The results of hydrobiological studies allow us to conclude the absence of environmental ecological risks for studied aquatic ecosystems. Studied transboundary rivers are not channels of cross-border transport of pollutants. Transboundary river network is the buffer system and ensures a high ecological quality of surface waters in the region.
