AB  - Vertical distribution of natural radionuclides, 137Cs and heavy metals were measured in soil and plants collected from Kragujevac surroundings. The activities of 226Ra, 232Th, 40K and 137Cs, were measured by gamma spectrometry in plants, soil and milk. The mean absorbed dose rate, annual effective dose, external hazard index and excess lifetime cancer risk were (81 ± 13) nGy h−1, (99 ± 16) μSv, (0.5 ± 0.1) and (3.8 ± 0.6) 10–4, respectively. The Spearman linear correlation coefficient was used to examine the relationship between heavy metal concentration and radionuclide. Unmix 6.0, was used to systematize abovementioned parameters in order to establish a data pattern.

AB  - After NATO bombing of Serbia in 1999, UNEP has identified Kragujevac as one of the four heavily polluted environmental "hot spots". Damaging of industrial and military targets caused the release of substantial amounts of hazardous chemical substances into the environment. This study was conducted in order to access the exposure of residents of Kragujevac city to persistent soil pollutants, twenty years after NATO air campaign. The paper reports the results of measuring radionuclides, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and heavy metals (As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn, and Hg) in soil samples collected from two depths (0-15 cm and 15-30 cm) at 30 locations along the riverbank of the Lepenica River. The average specific activities of Ra-226, Th-232, K-40 and Cs-137 were comparable to average worldwide values; excess lifetime cancer risk (ELCR) from natural radionuclides ranged from 1.1.10(-4) to 3.3.10(-4). The measured concentrations of As, Co, Cr, Cu, and Ni exceeded the limit values in most of the samples. Non-carcinogenic risk (hazard quotient and hazard index) and carcinogenic risk from heavy metals were assessed. Total hazard index was 0.257 and 2.16 for adults and children, respectively. Sum of measured PAHs ranged from 110 to 1026 mu g kg(-1). Sum of PCBs exceeded the limit value of 20 mu g kg(-1) in all samples (it ranged from 48.8 to 196.8 mu g kg(-1)), but it was still below the remediation level. The differences between two layers with respect to all measured variables were not statistically significant.

AB  - Transfer factors of natural radionuclides and (CS)-C-137 from soil to plants used in traditional medicine were determined. The transfer factors (TF) were calculated as Bq kg(-1) of dry plant per Bq kg(-1) of dry soil. Mass activity concentrations of Ra-226, Th-232, K-40 and Cs-137 in soil and plant samples were measured with high purity germanium detector (HPGe). The concentrations of As, Co, Cr, Cu, Mn, Ni, Pb and Zn were determined, as well as the cation exchange capacity (CEC) and the content of exchangeable cations (Ca, Mg, K, Na). Wide ranges of values were obtained for all the metals, especially for Cr and Ni. The Absalom model was used for determination of the amount of Cs-137 transferred from soil to plant based on soil characteristics such as pH, exchangeable potassium, humus and clay contents. The estimated transfer factors were in the range from 0.011 to 0.307 with an arithmetic mean of 0.071, median of 0.050, geometric mean of 0.053 and geometric standard deviation (GSD) of 2.08. This value agreed well with that calculated from the measurements of 0.069, geometric mean 0.040 and GSD 3.19. Correlations between radionuclides, metals, physicochemical properties and transfer factors were determined by Spearman correlation coefficient. There was a strong positive correlation between Cs-137 transfer factor and the ratio of transfer factor for K and Cs-137. Principal Component Analysis (PCA) was performed in order to identify some pattern of data.

AB  - Radioactivity concentrations and heavy metal content were measured in soil samples collected from the area of Kragujevac, one of the largest cities in Serbia. The specific activities of Ra-226, Th-232, K-40 and Cs-137 in 30 samples were measured by gamma spectrometry using an HPGe semiconductor detector. The average values +/- standard deviations were 33.5 +/- 8.2, 50.3 +/- 10.6, 425.8 +/- 75.7 and 40.2 +/- 26.3 Bq kg(-1), respectively. The activity concentrations of Ra-226, Th-232 and Cs-137 have shown normal distribution. The annual effective doses, radium equivalent activities, external hazard indexes and excess lifetime cancer risk were also estimated. A RAD7 device was used for measuring radon exhalation rates from several samples with highest content of Ra-226. The concentrations of As, Co, Cr, Cu, Mn, Ni, Pb and Zn were measured, as well as their EDTA extractable concentrations. Wide ranges of values were obtained, especially for Cr, Mn, Ni, Pb and Zn. The absence of normal distribution indicates anthropogenic origin of Cr, Ni, Pb and Zn. Correlations between radionuclide activities, heavy metal contents and physicochemical properties of analysed soil were determined by Spearman correlation coefficient. Strong positive correlation between Ra-226 and Th-232 was found.

AB  - Sequential extraction for the determination of zinc forms in soil has been applied in order to enable clearer understanding of its mobility and availability for plants. Examinations were conducted on 20 samples of soil with different chemical and physical characteristics; plant uptake was followed on oats (Avena sativa L). A fractional scheme was applied with extraction of (I) water soluble and exchangeable adsorbed metals, (II) specifically adsorbed metals and metal bounded with carbonates, (III) reductant releasable Zn, which included Zn bonded to oxides not released in the previous step, and probably included Zn occluded in oxides, (IV) organically bonded, and (V) (residual fraction) metal structurally bonded in silicates. The majority of zinc is in residual fraction (V) (74.9% in field vertisols and 69% in meadow vertisols). Reductant releasable Zn occluded in oxides (III) is the second largest with higher values in meadows (22.2%) than in fields (17.5%). The content of zinc in organic matter (IV) is small (6.7%) in both types of soil. Specifically adsorbed zinc, and zinc bonded with carbonates (II) is low (0.1-3.1), while its' content in exchangeable fraction (I) is negligible and is about 0.2%. Exchangeable and specifically adsorbed zinc increased with the reduction of the pH of soil, CEC, clay and clay + silt, and with the increase of silt and sand. Zinc in the residual fraction increases with the pH of soil, clay, CEC, and clay + silt. The concentration of residual zinc was determined by mechanical fraction of clay.

AB  - Western Serbia is a region well-known for potato production. Concentrations of selected metals, polycyclic aromatic hydrocarbons (PAHs) and radioactivity were measured in the soil in order to evaluate the quality and characteristics. The examined soils (Luvisol and Pseudogley) showed unsuitable agrochemical characteristics (acid reaction, low content of organic matter and potassium). Some samples contained Ni, Mn and Cr above the maximal permissible concentration (MPC). The average concentration of total PAHs was 1.92 mg/kg, which is larger than the maximal permissible concentration in Serbia but below the threshold values in the European Union for food production. The average radioactivity of U-238, Ra-226, Th-232, K-40 and the fission product Cs-137 were 60.4 +/- 26.2, 33.2 +/- 13.4, 49.1 +/- 18.5, 379 +/- 108 and 36.4 +/- 23.3 Bq/kg. Enhanced radioactivity in the soils was found. The total absorbed dose rate in air above the soil at 1 m height calculated for western Serbia was 73.4 nGy/h and the annual effective dose was 90 mu Sv, which are similar to earlier reports for the study region.

Some samples contained Ni, Mn and Cr above the maximal permissible concentration (MPC). The average concentration of total PAHs was 1.92 mg/kg, which is larger than the maximal permissible concentration in Serbia but below the threshold values in the European Union for food production. The average radioactivity of U-238, Ra-226, Th-232, K-40 and the fission product Cs-137 were 60.4 +/- 26.2, 33.2 +/- 13.4, 49.1 +/- 18.5, 379 +/- 108 and 36.4 +/- 23.3 Bq/kg. Enhanced radioactivity in the soils was found. The total absorbed dose rate in air above the soil at 1 m height calculated for western Serbia was 73.4 nGy/h and the annual effective dose was 90 mu Sv, which are similar to earlier reports for the study region.",
