SINOPSIS

Results of long-term investigations of the content of zinc and forms of its occurrence in the reservoirs of the Dnieper cascade and in some rivers and small water bodies located within the territory of Kiev have been generalized in the paper. In recent years, its concentration in the studied water bodies varied over a wide range – from 10.2 to 158.6 μg/L. Data on the content of zinc in rivers, lakes, and reservoirs of other regions of the world are also given for comparison. It has been found that in the polluted surface waters the concentration of Zn(II) attains hundreds and even thousands μg/L. Zinc migrates mainly in the dissolved state as a result of its binding into the complexes with natural organic ligands. Mass contribution of Zn(II) in the composition of suspended matter on the average accounts for 8.9–49.4% Zntotal. The contribution of zinc labile fraction (potentially bioavailable) is not more than 12.0–30.0% Zndis. Anionic complexes prevail among organic compounds of Zn(II). Their contribution on the average accounts for 44.8–54.8% Zndis. Their contribution increases with increasing the concentration of humic substances. Carbohydrates are of considerable importance in the process of complexation in summer and autumn. Thus, during these seasons the content of Zn(II) neutral complexes increases. Mainly organic compounds with the molecular mass ≤ 5.0 kDa are involved in the process of complexation with Zn2+ ions.
