Karazin popup.description2 Research object — valley landscapes of middle river flow Seversky Donets. Work aim — determination of diffusion conformities to natural laws and conduct of heavy metals in soils of different valley landscapes fazies Seversky Donets river. Research methods — landscape indication, a complex of physical and chemical methods — atomically-emissive spectral, roentgen phase and electronic raster microscopy. For laying of ecological monitoring of valley landscapes of middle flow Sev. Donets river used combination of landscape indication with complex of physical and chemical research methods for polutants to molecular level. This allowed in detail to clear up conduct confirmities to natural laws for polutants in soils of valley landscapes Sev. Donets river. By basic tendency pH of soils pending of vegetation season and on vertical profile is soils alkalinity of valley landscapes fazies, to the exclusion of uniformity section of central flood-lands fazie, where is fixed rise of acidity at close of vegetation. Fo r mobile forms Zn, Co, Pb is established augmentation of their amount in soils all fazies in vegetation beginning on comparison with their maintenance in winter soil standards; Ni and Cu have a tendency to augmentation of mobility in fazie soils of central flood-lands and swamped former river-bed lowering to the last of vegetation period; lowering of maintenance of their mobile forms in fazie soils of run-of-river flood-lands, high flood-lands by run-on terrace seam with flue terrace and hill top of flue terrace after period this. For mobile forms Cr, I, Sr fixed them maintenance dependence in soils from geomorphological relief peculiarities and definite augmentation tendency of their amount by in spring on comparison with winter period and lowering of their amount for the most of soils to ending of vegetation period, that conditioned by education of junctions of insoluble nature. In dependence on year (winter, spring, autumn) season changes maintenance changes dynamics nature polutants in soils explored fazi es: a spring is sharp changes of quantitative contained each separate element in soils from flood-lands fazie to hill top of flue terrace fazie; autumn is slow motion crooked of elements maintenance change in fazies soils. The received results are new and set up a base for laying of ecological monitoring on molecular level. Product Description popup.authors popup.nrat_date 2020-04-02 Close
