Filina Т. Ecologo-biochemical features of urboedaphotopes polluted with heavy metals of within bounds of Dnepropetrovsk.

The object is edaphotopes of technogenic territories of Dnepropetrovsk. The aim is to analyze of influencing of heavy metals in a structure of industrial lets on the changing of quality of a humus and biochemical activity edaphotopes for their ecological estimation. Methods are ecobiochemical, statistical. The features of maintenance and distribution of heavy metals in edaphotopes technogenesis of Dnepropetrovsk are explored. Influence of technogenesis on a status of organic substance of soils is studied: reduction in total humus; change of its fractional composition that finds display in increase in a stake of fulvic acids; reduction of quantity of humic acids; decrease in structure of hydrocarbons and elements of mineral feed of plants. In technozems, testing action of industrial emissions, containing compounds of heavy metals, activity of hydromanhole and oxidation-reduction enzymes of soils is reduced. The differentiated action of industrial pollutants on biochemical activity of soils in conditionsof modeling experience is found out. The basic carriers of enzymes are revealed at their localization in soil - fractions humic acids. Influence of the industrial emissions containing heavy metals on localization of enzymes, which is shown in reduction of enzyme activity of preparations of humic acids, and increase in this process of a role of fulvic acids and humin, is established. Spheres of use are monitoring, training courses.
