| Description | The main aim of the study was to evaluate a level of contamination by selected elements (zinc, lead, copper and arsenic) in soils from the southeastern part of Drahany Upland. In total, it has been collected forty-eight topsoil samples (DV01-DV48) and sixteen surface water samples (W1-W16). The heavy metal concentration has been detected by X-ray fluorescence spectroscopy (XRF) in the topsoil samples and Atomic Absorption Spectroscopy (AAS) in the surface water samples. The heavy metal mobility has been evaluated by the BCR Sequential Extraction Procedure. The Index of Geoaccumulation (I-geo) reported that the study area rang among uncontaminated or moderately contaminated by heavy metals. According to the Coefficient of Industrial Pollution (CIP) the soils are medium contaminated. The BCR method proved that lead and zinc are the most mobile elements under reducible conditions in the natural background soils, otherwise in the soils of excepted contaminated site, heavy metals have been mostly held in residual fraction. The low mobility of cuprum and arsenic has been reported in the soils. In fact, the copper and arsenic are not supposed to being come into the soil environment and into the plants, either. |
