Abstract

The present paper examines and compares heavy metal contents in soils from two altitudinal sequences in the northern and the central Tian-Shan mountains. The soil horizons of 11 sites were described, sampled, analysed, interpreted and classified. Results show that pedological processes similar to those responsible for the development of steppe chernozems are active even at very high elevations. In order to verify the degree of accumulation and possible ecotoxicity, the distribution and mobility of Cd, Cr, Cu, Zn, Pb, and Ni within soil profiles were checked. Relationships among elements and other pedological parameters, such as organic carbon content, pH, texture, etc., were investigated. Lastly, the possible risk of contamination was assessed. - (EN)
