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  - In most European countries, each adult citizen drinks on average more than 20 L of wine every year. Three popular wine-growing areas (Aleksandrovac, Topola, and Orahovac) in Serbia were studied in order to investigate the abundance and uptake of elements from vineyard soil to plants. The specific activities of radionuclides (226Ra, 232Th, 40K, 137Cs, and 7Be) were measured in soil, leaves, and grape berries. 226Ra and 232Th were positively correlated with silt and clay and negatively correlated with sand content in soil. Specific activities of natural radionuclides were also negatively correlated with soil pH and CaCO3. Significant correlations of 40K and 137Cs with organic matter in soil were found. Concentrations of fifteen metals (As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn, Fe, K, Na, Ca, Mg, and Hg) were also measured in soil samples as well as in grapevine leaves. Analyzed soils were rich in Ni, Cu, Co, Cr, and Cd. High concentrations of Cu were probably caused by long-term use of Cu-based fungicides. Cu was correlated with Fe and organic matter content in soil. Soil-to-plant transfer factors (TF) were calculated to estimate the uptake of radionuclides and metals. Correlations obtained via PCA enable distinction between the sites Aleksandrovac and Topola relative to Orahovac. The first principal component (PC1) accounting for 30.70% of the total variance correlated significantly with soil pH (H2O), contents of CaCO3, Na, Ca, 40K, and 226Ra in soil, as well as with 226Ra, Na, Ca in plants and TFCa. The second principal component (PC2), with total variance of 17.21%, was mainly correlated with variables pertaining to Mg, Co, and Cr in the soil and TFK.

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  - This paper reports the results of radioactivity concentrations and heavy metal content in soil samples collected from non-agricultural areas in the municipality and vicinity of North Kosovska Mitrovica, formerly the most important mining area in Europe. The estimated average activity concentrations of Ra-226, Th-232, K-40 and Cs-137 are 40.6 +/- 19, 48 +/- 25.4, 743.2 +/- 200.5 and 81 +/- 119 Bq kg(-1), respectively. The estimated average absorbed dose rate in the air and the annual effective dose are 78.7 nGy h(-1) and 96.6 mu Sv, respectively. The radium equivalent activity and external hazard index were also calculated. High contents of Pb, Zn, Cu, Cd, As and Ni were found in the analyzed soil samples, thus indicating pollution of the environment. Most metals have a wide range of values spanning 2 to 3 orders of magnitude, which is particularly evident for Pb and Zn. Correlations between the activity concentrations of the radionuclides, the heavy metal content in soil and the basic soil properties were determined by means of the Pearson linear coefficient. Strong positive correlations between the naturally occurring radionuclides, and also among Pb, Zn, Cu and Cd were 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.",
