POTENTIALLY TOXIC ELEMENTS IN SOILS AND PLANTS ON A RECLAIMED COAL-WASTE DUMP IN SOUTHERN POLAND (PRELIMINARY STUDY)

摘要

The phase composition and concentrations of six potentially toxic elements (Zn, Pb, Mn, Cu, Ni, and Cd) in topsoil and plants were studied. The samples were taken from the waste dump in Katowice in the Upper Silesian Coal Basin. Mineral matter was identified by XRD and SEM. Mineral composition of studied topsoils depends on material composition used to forming the surface layer on the dump. There aluminosilicates (chlorite, muscovite, clays minerals), quartz, Fe and Ca sulphates and Fe oxides dominate. On plants shoots there were identified dolomites, Fe oxides, Ca sulphates, Na and K chlorides and rarely Au-Cu alloys beside quartz and aluminosilicates.
