Heavy Metals in Surface Waters of Ukraine: Their Content and Forms of Migration

ABSTRAKT

The results of long-term investigations of the content of some heavy metals (Mn, Cu, Zn, Pb, Cr, Cd) and forms of their migration in the water of the Dnieper reservoirs, Dnieper-Bug estuary, Dniester estuary, and the Ukrainian section of the Danube river are considered. Comparative studies were carried out on the influence of processes of adsorption and complexation upon the migration mobility of the studied metals and relationship between the forms of their occurrence in water bodies differing in their hydrological regime. It has been found that binding of heavy metals into complexes with dissolved organic substances or their adsorption on suspended particles is mainly responsible for the low content of "free" ions, which are among the most toxic forms.
