摘要：

The major objective of this study was to investigate the chemical forms in which selected metals occur in soils polluted with metallurgical dusts as well as to estimate potential mobility and bioavailability of these metals. Six soil profiles situated at different distances from Cu smelters were chosen and soil samples were taken from top- and sub-surface layers. The soils differed in their textures but all of them showed high contents of sand fraction and were neutral or slightly alkaline in reaction, due to liming. Ale research involved the analysis of the total contents of 8 metals (Al, Fe, Mn, Zn, Cr, Ni, Cu and Pb) and their speciation according to the Zeien and Bruemmer method. Total concentrations of metals varied in the following ranges (mg/kg): Al, 1420-11,400; Fe, 1710-19,700; Mn, 55-470; Zn, 6.4-153; Cr, 2.15-16.9; Ni, 1.18-13.8; Cu, 7.4-1710; Pb, 11-460. The metal fractions determined were: mobile, exchangeable, occluded in MnO
