The results of many years of investigation into the content and migration forms of a number of heavy metals (Mn, Cu, Zn, Pb, Cr) in the water of the Dnieper and the Danube are considered. Comparative appraisal of the influence of adsorption and complexing processes on the migration mobility of the investigated metals, and the ratio of their forms existing in waterbodies with different hydrological regimes, are given. The importance of investigating these processes forestimating the ecotoxicological state of aquatic ecosystems is shown. The binding of heavy metals in complexes with dissolved organic matter (in the Dnieper reservoirs) or their adsorption on to suspended particles (in the Danube) are the main cause of a low content of free ions as one of the most toxic forms.
