要約

Paper deals with data on metals migration (Mn, Al, Cu, Zn, Pb, Cr) within the system “bottom sediments − water” depending on the oxygen regime of the water bodies. Oxygen saturation rate in the surface layer of the Kaniv reservoir in the investigation period amounted to 48.7−84.7%, and in the near-bottom layer oxygen deficit was observed (0.4−0.9 mg/dm3). In the Telbin Lake the surface layer was over-saturated by oxygen (119−206%), whereas in the near-bottom layer oxygen content during some months was at zero level. This fact caused intensive manganese migration from the bottom sediments. Its concentration in the near-bottom layer increased about 25 times in the Kaniv reservoir and 50−60 times in the Telbin Lake. Migration of other considered metals was incommensurably less. Data on relation of the suspended and dissolved metals forms, as well as their free (hydrated) ions and complex compounds with dissolved organic matters (DOM) are considered. Chemical nature of complexes and peculiarities of the metals fixation by different DOM fractions in the studied water bodies are discussed
