Abstract

Data on the composition and quality of water in the river Cherek were obtained by monitoring of seasonal changes in the concentrations of pollutants therein under changing climate. The studies were carried out in the foothill and estuarine zones over a three-year period. The seasonal dynamics of the concentrations of ingredients was noted, and changes in the concentrations of trace elements (Cr, Ni, Mo, Mn, Zn, Pb) and environmental toxicants (NO3‒, NO2‒, NH4+) were compared. It was found that in recent years the concentrations of some elements in the river water tended to increase, whereas the others remained within the normal range. The seasonal variability of concentrations in winter low water and summer rain floods over a three-year period and of the main pollutants were identified. The interannual variability of the concentrations of trace elements and environmental toxicants is considered.
