The Distribution Peculiarities of the Highly Hazardous (pb, Zn) and Moderately Hazardous (cr, Co, Ni, Cu) Chemical Elements in the Humus Horizon of the Mountain-meadow Sod Soil of the Subalpine Landscape of the North-east Slope of South-eastern Part of the Greater Caucasus (azerbaijan)

Abstract: The study of contents in the mountain-meadow sod soil of the landscape revealed of the north-east slope of south-eastern part of the Greater Caucasus the nickel, lead concentrations and the cobalt migration in upper horizon. appear inert. According to the studied elements the soil of landscape is slightly contaminated. The copper and the cobalt are characterized by optimum contents. The zinc appears by abundant content, but lacking toxicity, the lead is conditionally contaminated. The comparative analysis of the geochemical parameters of elements distribution in the continental soils and in humus horizon of the mountain-meadow sod soil of subalpine landscape revealed visible differences in the landscape soil due to the peculiarities of element composition of soil-forming materials and of soil formation The received data on the geochemical peculiarities of the elements in the mountain-meadow sod soil allow estimating the pollution degree, the optimum, abundant and deficient content of elements in the soil of subalpine landscape. The clark contents in the continental soils have been accepted as Cr, Co, Ni, Cu, Zn, Pb geochemical background to assess the soil pollution extent of landscape It has been concluded that, Ni, Pb noticeable enrichment, Cr, Zn, Cu clark contents and Co depletion are the regional geochemical peculiarities of humus horizon of the mountain-meadow sod soil of subalpine landscape, as opposed to the clark elements content in the continental soils. The weak acid and neutral conditions of humus horizon contributes to the development of equivalent directivity of the processes of accumulation (Ni, Pb) and migration (Co) of the elements. The heterogeneous, high humus content does not significantly influence on the elements distribution in humus horizon.
