nalysis of landscape geochemical conditions of the territory of Kivertsi National Nature Park “Tsumanska Pushcha” was carried out also the levels of pollution of landscapes within the park and adjacent territories were established. Features of the accumulation and distribution of pollutants in the landscapes of the territory under conditions of natural and Technogenic geochemical anomalies are considered. The landscapes of the studied migration classes (calcium, calcium carbonate, carbonate clayey, acidic calcium) are characterized by a relatively high coefficient of migration intensity due to relatively weak buffering capacity, low water retention capacity and contrasting moisture regime. However, strong gleyed horizons are able to fix contaminants during their surface movement. Using the methods of landscape geochemical research, analytical methods, data on the gross and mobile content of heavy metals were obtained and analyzed. The highest concentrations of manganese and chromium are found in soils differentiated on loess sediments, nickel and copper on glacial sediments. Most of the studied heavy metals exceed the regional geochemical background. In terms of the gross content in soils, trace elements form the following geochemical series: Zn>Cu>Pb>Ni>Mn>Cr. The accumulation of lead up to 2-3 MPC in forest litters is clearly traced. Dependences of the stability of landscapes to Technogenic pollution on the level of conservation of natural geochemical parameters of soils, the degree of their anthropogenic transformation and the level of heavy metals incomings have been established. All studied plants maximally accumulated Mn, Cu, Cr and minimally Zn and Ti which is consistent with the patterns of migration of these elements in the soil. The high accumulation of heavy metals in the aboveground part of the studied plants indicates a significant removal of elements from the soil, which, in turn, makes it possible to consider certain plant species as potential phytoremediators. According to the average values of the concentration of macro elements in plants, the following geochemical series is established: CaO>K2O>MgO>P2O5>SiO2>SO3> Al2O3> Fe2O3>Na2O>TiO2. On the basis of the data obtained, 4 types of biogeochemical bonds between chemical elements in the soil – plant system for the territory of the NPP were identified: V, Ti - soil> plant; Ni - soil <plant; Cr - soil> plant; Mn, Cu - soil <plant.
The study presents the results of the spatial distribution of the heavy metal contents in separate components of the landscape of Kivertsi National Nature Park “Tsumanska Pushcha”. The article provides the quantitative indices of the heavy metals contents, which represent the intensity, character, and specificity of the accumulation in the soil horizons. Concentrations of the microelements fluctuate depending on the lithological type of deposits, their facies affiliation, and localization in the drainage basin. The contents of nickel, cobalt, lead, chromium, vanadium, manganese, and copper are characterized by significant divergence from their average concentrations, though it doesn’t exceed their estimated abnormal indices. Most of the studied heavy metals in the soil exceed the regional geochemical background. The biggest accumulation of copper and zinc is taking place in the forest floor, and the mineral part of the profile is lightly marked by alluvial and illuvial character. The contents of nickel, cobalt, and manganese are increasing with the depth with the accumulation of these elements, which are typical of the chemical contents of glacial deposits. The forest floor is distinctly playing the role of a barrier that prevents copper from penetration into the inner levels of occurring soil horizons. The paper defines the dependence of the heavy metal contents in plants of the national nature park on the level of technogenic load and characteristics of the soil covering of the territory. With the increase of the heavy metals in soil, they accumulate in plants. Though, with the distance from the source of contamination, the contents of the heavy metals in plants decrease by 10-20 mg/kg. The study of the most common plants, which grow on the soils of diverse mechanical contents, revealed that the plants which grow on sod-podzolic sandy soil display the biggest number of microelements, while those growing on bog soil and peat bogs. The main part of the exceeding background indices according to the elements has been found in sample areas westwards. All plants under research accumulated Mn, Cu, Cr to a maximal extent while Zn and Ti to a minimal extent, which is in accordance with elements migration of this group. The main directions of further research include the study of heavy metals distribution in diverse genetic types of the soils; definition of the standard contents of the elements in geochemical landscapes needed to identify the intensity of migration and character of elements distribution; performance of biochemical zoning.
Results of the study about pollutants content in soils of urbanized landscapes are presented. Patterns of their migration and accumulation in main soil types of Brovary are grounded. Correlation relationships between the individual components of ecologicalgeochemical system of urbanized territory were analyzed. Dependences of landscape resistance to technogenic pollution on the level of conservation of natural geochemical parameters of soils, degree of their anthropogenic transformation and level of heavy metals were determined. According to geochemical criteria technogenic associations of heavy metalsin soils are determined, which are represented by the following elements: Cu>Pb>Zn>Co>Cr>V>Mo>Mn>Ni. Level of gross content of chemical elements compounds in soils of different zones of the city is heterogeneous. City zones with the highest polyelement contamination of soil have been identified. Maximum technogenic load is recorded in urban areas of transport infrastructure zone and zone of production and communal-warehouse facilities. Ecological and geochemical assessment on the total index of pollution by using methods of Y.E. Saeta, is shown. Value of this topsoil parameter in Brovary (0-10 cm) ranges from 30 to 106, the average is 65, which corresponds to hazardous level of soil pollution. According to the total indicator of technogenic pollution, Brovary belongs to cities with high pollution level. Soils in all parts of the city, except for residential areas, are classified as hazardous. Studied soils of the city are characterized by plumbum geochemical specialization. High levels of zinc, manganese, cobalt and chromium were also found (the maximal permissible concentrations in soil exceeds by 1.7-4.7 times). Especial attention is paid to the patterns, mechanisms of pollutants influence on the complex of soil properties and processes that determine the ecological condition of soils and their resistance to anthropogenic flows. Soil contamination by pollutants leads to changes in their physical and chemical properties (cation exchange capacity pH, organic matter content) which causes a low buffering capacity of soil cover of the city.
