Myslyva T. Еcotoxicological evaluation of components of agricultural and urbolandscapes of Zhytomyr Polissya after maintenance of row of heavy metals

The results of 10-years-old researches, devoted establishment the features of migration and accumulation of heavy metals (Cu, Pb, Cd, Zn) in components of natural, agro-, park and recreation and agrosettle landscapes are expounded. The features of migration of Cu Pb, Cd, Zn in the type of basic soils are set as well as the coefficients of danger of maintenance of mobile forms of pollutants in overhead 0-20 sm horizons of the ground type are certain and the cartographic models of maintenance of mobile lead and cadmium in soil are developed. The levels of heavy metals contaminations the urbanozems and phytocenoses on the territories of park and recreation and agrosettle landscapes in Zhytomyr as well as the ground cover and plant-grower products in the personal private economies within the limits of rural settlements of 15-kilometre suburban area are appraised. Stochastic models which allow to prognosis the level of Cu, Zn contaminations of potato and vegetables and card-chart of Cu, Pb, Cd, Zn contamination of urbanozems, vegetables and potato are developed. The estimation of heavy metals contamination of superficial and underground waters, waters of bogs and peats is conducted, and also effects of pirogenic degradation of peat soils are analyzed. The information about the morphological features of pirogenic formations, its physical and physical and chemical properties, maintenance of macronutrients and heavy metals is resulted. The features of accumulation of Cu, Pb, Cd, Zn, Mo and Mn by the wild-growing representatives of arboreal and grassy vegetation, bryophytes and cladinas are certain. The problems, which touch the possibility of realization of the ecological setting of norms of heavy metals on the basis of integral index of the ecological and biological state and violation of complex of properties and processes which determine the ecological functions of soil, are considered. The recommendations on the conduct of agricultural production in a private sector in the conditions of the increased anthropogenic influence on an environment are developed.
