Sažetak
In this paper the matrix characterization of chosen solid environmental samples and assessment of its impact on the association of risk metals with mineral phases of these samples, which makes their mobility in the environment, is presented. Results of X-ray diffraction analysis, determination of total carbon contents (TOC, TIC) and constituent elements have confirmed differences in the mineralogical composition of samples. In the soil and sediment samples, more than 80 % content of mineral forms of silicon and silicates was determined, moreover sediment contains also carbonates. In the sample of gravitation dust sediment (GDS), high (approx. 80 %) content of amorphous material was determined. The rest was formed from a wide variety of minerals. In comparison with two other samples under study, amount of GDS in the environment is least, but in spite of this it significantly influences input of heavy metals to the soils, particularly in the industrial areas.
