Gerasimchuk L. Аccumulation of heavy metals in urboedaphotops and phytocenosis of Zhytomyr Polissya

The results of the 5-years-old (2007 - 2011) researches devoted to establishment of conformities to the law of migration and accumulation of heavy metals (Cu, Zn, Pb, Cd) in the components on the territories of park and recreation and agrosettle landscapes are generalized. Conducted estimation of levels of contamination by the heavy metals of urbanozems and phytocenosis on territory on the territories of park and recreation landscapes, and soil cover and plant-grower products reared within the limits of the agrosettle landscapes in Zhytomyr. Developed stochastic models which enable to prognoses contaminations of potato and the Cu and Zn vegetables and card-chart of the Cu contamination, Pb, Cd, Zn urbanozems, vegetables and potato. The exposed conformities to the law of influencing of impact polymetalic contamination by copper, zinc, cadmium and lead on biological and fermentative activity of soil, quantity soil's microorganisms, their biomass, and also psychotically of the soil. It is set that bioindication of іmpact polymetallic contamination of soddy podzolic soil, equivalent 10 - 15 maximum permissible concentration, it follows to conduct on the basis of the use of micromycets. Set the dynamics of migration of the mobile forms Cu, Zn, Pb and Cd in soil profile of soddy podzolic sandy loam soil during 2008-2010 years at the levels of іmpact contamination, equivalent 1 MPC, 5 MPC, 10 MPC and 15 MPC, and realizable prognosis of their migration on 2011-2013. The constants of speed of destroying of heavy metals with 0-20 см of layer of soil and their half removal period are set.
