Abstract
The state of surface waters, which are polluted with the waste of the lead-zinc enriching factory in Salair city (Kemerovo Region), is described. The total salt composition, total content of elements and their distribution in surface water downstream the river, in suspension and bottom sediments, and also the amount and fractions of mobile forms are studied. It is noted that Zn, Cd migrate in water generally in the truly dissolved form, Ba, Fe, Pb in the sorbed one, Cu, As are distributed approximately equally between these forms. It is shown that the elements are accumulated and fixed in bottom sediments, but they can become a cause of secondary pollution with the acidification of the medium. For the given region, the metals Ba, Zn, Cu, Cd are the most dangerous ones in the ecological aspect.
