Buts Y. The dynamic of pollution by heavy metals of small river's watershed landscapes of Sumy area forest-steppe

Object of research: watershed landscapes of Sumy forest-steppe. Purpose of research: determination of regularities of seasonal dynamic contents heavy metals in the natural-territorial complexes of small river's watershed of Sumy forest-steppe area and reveals the degree of their pollution in comparison with the reservation landscapes. Methods: atomic-absorptinal analysis, X-ray analysis. Results, novelty: the degree of pollution of soil by heavy metals reveals in comparision with the chernozem of "Mykhaylivska tcelina"; the intensity of biological absorption of heavy metals by vegetation is determined; the main regularities of con-tents growth of heavy metals in the reservation landscapes and their anthropogenic modifications are considered. Usage area: geoecological monitoring of landscapes.
