The Effect of a Thermal Power Station on the Concentrations of Metals and Silicon in the Water of a Small Siberian River

Studying of the distribution of elements in the Beresh River water showed the concentrations of elements to decrease according to the series Ca > Na > Mg > Si > K > Sr > Fe > Al and the river water self-purification capacity for these elements to be inadequate. Concentrations of elements dramatically increase in the river reach near the Thermal Power Station (GRES) and next increase even greater in the lower reach of the river before its emptying into the Uryup River. It is shown that the seasonal variations, typical of the river upper and middle reaches and determining the high level of anthropogenic impact of the fuel and energy complex facilities onto the river, even out in the lower reaches of the river. Specific features of seasonal and spatial variations in the element concentrations for the 8 years of observations are discussed.[PUBLICATION ABSTRACT]
