Sažetak
The objective of this study was chemical characterization of soil samples affected by the dust emission and slag dumping from ferrochromium smelter as well as uptake of metals by vegetation growing on that soil. Altogether, 38 samples were collected including unpolluted background soil samples, polluted soil samples taken in the vicinity of the factory, slag material, bottom and fly ash. Grass material was also taken from both polluted and unpolluted soil. All samples were analyzed with energy dispersive X-ray fluorescence (EDXRF). Obtained results showed increased metal concentrations, up to 56 times (especially chromium and manganese), in soil samples taken in the vicinity of the factory compared to normal background soil concentrations. Slag material, fly and bottom ash were highly enriched in chromium, manganese and nickel. Chromium uptake by vegetation growing on the contaminated soil was found to be significant.
