[Hygienic evaluation of transboundary pollution of the Ural River basin].
The anthropogenic pollution of the Ural River and its tributaries is the most important problem of the Ural-Caspian basin. Transboundary inflow from Kazakhstan to Russian is 30.9 km3/year. The border Ilek river pollution was hygienically evaluated and the contribution of pollution sources was ascertained, with the seasonal variations and hydrochemical background being kept in mind, from 2002 to 2007. The monitoring data on the content of priority pollutants of the surface waters of the basin of the Ilek River, a tributary of the Ural River, which come from the Republic of Kazakhstan, are given. Semiquantitative spectral estimation and the atomic absorption method were used to study the chemical composition of bottom sediments in the Ilek River and its tributaries. The magnitude and sources of influence of man-caused pollution on the quality of the river water were established.
