AB  - The optimized three-step sequential extraction procedure for the fractionation of micro- and macroelements, was conducted
to determine fractional characteristics of PTEs (potentially toxic elements) in surface sediments of rivers in the Vlasina
watershed. The sequential extraction results, which enable the evaluation of mobility of the studied elements, have indicated
that Zn, Ni, Cu, Cr, and As can be considered slightly mobile, whereas Pb, Mn, Cd, and Co were regarded as possibly mobile
elements. Lead was dominantly bounded (specifcally adsorbed or co-precipitated) to iron and manganese oxides (up to 80%)
and may be released by reduction. Since the content of the exchangeable fraction (F1) is an indicator for anthropogenic impact
on the aquatic environment, a low percentage (0–8%) of studied toxic elements in this fraction indicated that these elements
have lithogenic origin in most sampling locations in the area of study. Except for Pb, the substantial positive correlations
between Al and other elements showed that studied elements came primarily from terrigenous sources. Although the values
obtained for the risk assessment code (RAC) indicated a slightly increased mobility of some elements (up to 22.44%), the
values of the modifed risk assessment code (mRAC), which include toxic efects on the environment, showed there is no
danger of pollution by studied elements (all values were<1%). Our recommendation is to use mRAC instead of RAC in
ecochemical studies and assessment of the degree of sediment and soil pollution, because mRAC includes toxic efects of
elements. Based on ATI values, river sediments show no toxic to a low toxic degree. Even though obtained results indicate
that there was no considerable risk for river water contamination, the ecological risk for Fe and Pb should be monitored in
the future.

AB  - Increasing pollutant levels in surface water are a very important problem in developing countries. In Serbia, the largest rivers are transboundary rivers that cross the border already polluted. Taking this into account, evaluation of the distribution characteristics, ecological risk, and sources of toxic elements in river water and surface sediments in the watercourses of the Vlasina watershed is of great significance for the protection of water resources in Serbia. A total of 17 sediment and 18 water samples were collected and analyzed by Inductively Coupled Plasma—Optical Emission spectrometry (ICP-OES) and Inductively Coupled Plasma—Mass spectrometry (ICP-MS) to determine micro- and macroelements contents. The geo-accumulation index (Igeo) was applied to determine and classify the magnitude of toxic element pollution in this river sediment. The contents of the studied toxic elements were below water and sediment quality guidelines. For studied river water, results of principal component analysis (PCA) indicated the difference in behavior of Cr, Mn, Ni, Cu, and As and V, respectively. Cluster analysis (CA) classified water samples according to As and Cu content. The PCA results revealed that lead in river sediments had different behavior than other elements and can be associated mainly with anthropogenic sources. According to the degree of Igeo, the majority of sediments in the Vlasina region were uncontaminated regarding studied toxic elements. The origin of elements is mostly from natural processes such as soil and rock weathering.

AB  - This work presents characteristics of atmospheric aerosols of urban central Balkans area, using a size-segregated aerosol sampling method, calculation of mass distributions, SEM/EDX characterization, and ICP/MS analysis. Three types of mass distributions were observed: distribution with a pronounced domination of coarse mode, bimodal distribution, and distribution with minimum at 1 mu m describing the urban aerosol. SEM/EDX analyses have shown morphological difference and variation in the content of elements in samples. EDX spectra demonstrate that particles generally contain the following elements: Al, Ca, K, Fe, Mg, Ni, K, Si, S. Additionally, the presence of As, Br, Sn, and Zn found in air masses from southeast segment points out the anthropogenic activities most probably from mining activities in southeastern part of Serbia. The ratio Al/Si equivalent to the ratio of desert dust was associated with air masses coming from southeastern and southwestern segments, pointing to influences from North Africa and Middle East desert areas whereas the Al/Si ratio in other samples is significantly lower. In several samples, we found high values of aluminum in the nucleation mode. Samples with low share of crustal elements in the coarse mode are collected when Mediterranean air masses prevailed, while high share in the coarse mode was associated with continental air masses that could be one of the approaches for identification of the aerosol origin.

AB  - Size-segregated aerosol samples were collected using six stages High Volume Cascade Impactor. Aerosol mass and water soluble ions concentrations were determined. The Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model was used to study the origin of air masses arriving to Belgrade in the investigated period. The obtained results of aerosol mass and water-soluble ion concentrations have been divided into six sub-data sets based on air mass categories. The highest average mass concentration of the fine mode (D-p  lt = 0.49 mu m) was found for air masses coming to Belgrade from the southeast and northwest directions, and of the coarse mode (3.0  lt  D-p  lt = 7.2 mu m) for air masses arriving from the northwest direction. The highest concentrations of SO42- were found in the fine particles transported to the investigated area by air masses from southeast direction. The analysis of contribution of marine aerosol components (Na+ and Cl-), the Correlation and Cluster Analysis indicated the influence of marine aerosol on urban aerosol of the central Balkans coming from the Western Mediterranean and northern direction. NH4+ and SO42- and K+ dominated in the fine mode for all air mass categories. PCA demonstrated the dominant impact of secondary aerosol formation processes on urban aerosols.

AB  - Size segregated particulate samples of atmospheric aerosols in urban site of continental part of Balkans were collected during 6 months in 2008. Six stages impactor in the size ranges: Dp  lt = 0.49 mu m, 0.49 lt Dp  lt = 0.95 mu m, 0.95 lt Dp  lt = 1.5 mu m, 1.5 lt Dp  lt = 3.0 mu m, 3.0 lt Dp  lt = 7.2 mu m, and 7.2 lt Dp  lt = 10.0 mu m was applied for sampling. ICP-MS was used to quantify elements: Al, As, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, Li, Na, Ni, Mg, Mn, Pb, Sb, V, and Zn. Two main groups of elements were investigated: (1) K, V, Ni, Zn, Pb, As, and Cd with high domination in nuclei mode indicating the combustion processes as a dominant sources and (2) Al, Fe, Ca, Mg, Na, Cr, Ga, Co, and Li in coarse mode indicating mechanical processes as their main origin. The strictly crustal origin is for Mg, Fe, Ca, and Co while for As, Cd, K, V, Ni, Cu, Pb, and Zn dominates the anthropogenic influence. The PCA analysis has shown that main contribution is of resuspension (PC1, sigma(2)approximate to 30 %) followed by traffic (PC2, sigma(2)approximate to 20 %) that are together contributing around 50 % of elements in the investigated urban aerosol. The EF model shows that major origin of Cd, K, V, Ni, Cu, Pb, Zn, and As in the fine mode is from the anthropogenic sources while increase of their contents in the coarse particles indicates their deposition from the atmosphere and soil contamination. This approach is useful for the assessment of the local resuspension influence on element's contents in the aerosol and also for the evaluation of the historical pollution of soil caused by deposition of metals from the atmosphere.

abstract = "Size segregated particulate samples of atmospheric aerosols in urban site of continental part of Balkans were collected during 6 months in 2008. Six stages impactor in the size ranges: Dp  lt = 0.49 mu m, 0.49 lt Dp  lt = 0.95 mu m, 0.95 lt Dp  lt = 1.5 mu m, 1.5 lt Dp  lt = 3.0 mu m, 3.0 lt Dp  lt = 7.2 mu m, and 7.2 lt Dp  lt = 10.0 mu m was applied for sampling. ICP-MS was used to quantify elements: Al, As, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, Li, Na, Ni, Mg, Mn, Pb, Sb, V, and Zn. Two main groups of elements were investigated: (1) K, V, Ni, Zn, Pb, As, and Cd with high domination in nuclei mode indicating the combustion processes as a dominant sources and (2) Al, Fe, Ca, Mg, Na, Cr, Ga, Co, and Li in coarse mode indicating mechanical processes as their main origin. The strictly crustal origin is for Mg, Fe, Ca, and Co while for As, Cd, K, V, Ni, Cu, Pb, and Zn dominates the anthropogenic influence. The PCA analysis has shown that main contribution is of resuspension (PC1, sigma(2)approximate to 30 %) followed by traffic (PC2, sigma(2)approximate to 20 %) that are together contributing around 50 % of elements in the investigated urban aerosol. The EF model shows that major origin of Cd, K, V, Ni, Cu, Pb, Zn, and As in the fine mode is from the anthropogenic sources while increase of their contents in the coarse particles indicates their deposition from the atmosphere and soil contamination. This approach is useful for the assessment of the local resuspension influence on element's contents in the aerosol and also for the evaluation of the historical pollution of soil caused by deposition of metals from the atmosphere.",

AB  - This work focuses on the heavy metals contents of the size-segregated urban aerosol of the continental area of Balkans. The distribution of nano/micron heavy metals in the size-segregated urban aerosol of Belgrade center was studied during the summer-autumn of 2008. The particle size distribution in the size ranges D-p  lt = 0.49 mu m, 0.49  lt = D-p  lt = 0.95 mu m, 0.95  lt = D-p  lt = 1.5 mu m, 1.5  lt = D-p  lt = 3.0 mu m, 3.0  lt = D-p  lt = 7.2 mu m and D-p  lt = 7.2 mu m was measured. The aerosol samples were submitted to gravimetric and chemical analyses. The obtained mean mass concentration of the PM fractions was in accordance with an urban aerosol distribution. The aerosol mass concentrations were determined by gravimetric measurements (m(GM)) and, for heavy metals analyzed by ICP/MS.

AB  - The distribution of nano/micron inorganic main ions in the size-segregated urban aerosol of Belgrade center was studied during the summer-autumn of 2008. The particle size distribution in the size ranges D(p)  lt = 0.49 mu m, 0.49  lt = D(p)  lt = 0.95 mu m, 0.95  lt = D(p)  lt = 1.5 mu m, 1.5  lt = D(p)  lt = 3.0 mu m, 3.0  lt = D(p)  lt = 7.2 mu m and D(p)  gt = 7.2 mu m was measured. The aerosol samples were submitted to gravimetric and chemical analyses. The obtained mean mass concentration of the PM fractions was in accordance with an urban aerosol distribution. The aerosol mass concentrations were determined by gravimetric measurements (m(GM)) and, analyzed by ion chromatography for Na(+), NH(4)(+), K(+), Mg(2+), Ca(2+), Cl(-), NO(3)(-), PO(4)(3-) and SO(4)(2-). The mean random uncertainties associated with the determinations of Na(+), NH(4)(+), K(+), Mg(2+), Ca(2+), Cl(-), NO(3)(-) and SO(4)(2-) were assessed. The absolute highest concentration is found for SO(4)(2-) (1555.8 +/- 973.6 ng m(-3)) in the range of D(p)  lt = 0.49 mu m with an average participation of 8.19% to the total mass of the particles. The highest coefficients of correlation were found between NH(4)(+) and SO(4)(2-). Principal component analysis, PCA, was used for the identification and evaluation of the contributions of the main emission sources to the contents of water soluble ions in the urban aerosol. The formation of (NH(4))(2)SO(4) was found to be the dominant process. The influences of local urban (traffic) and regional industrial sources (nearby city Pancevo) were identified and a contribution of marine aerosol was observed. (C) 2011 Elsevier Ltd.

AB  - In order to assess the effects of the 1999 NATO bombing of Serbia on the environment, some of the most widespread and feared pollutants, including heavy metals were determined in various sediment samples that were taken from three areas hit by bombing and were previously well-known for its unpolluted environment. Samples of soil and sediments from Fruska Gora National Park as well as Deliblatska Pescara and Zasavica Protected Areas which all lie in the immediate vicinity of the Danube, were investigated by sequential extraction, in order to determine potential substrates of heavy metals and to predict their potential mobilization mechanisms into the environment, especially into surface and ground water flows. This was important because the Danube, one of Europe's most important rivers, flows in the immediate vicinity of the National Park and Protected Areas and any contamination could cause severe effects on the river's ecological status and unpredictable consequences on the countries downstream, including the ecology of the Black Sea. Results show that all three examined areas are polluted with cadmium, the main source of which is projectiles (i.e. their explosions which could contaminate the examined sediments). In Deliblatska Pescara Protected Area there is an increase of highly mobile lead, most probably originating from the bombing of Pancevo oil industry facilities. Radioactivity in examined sediment samples is in the range of values commonly reported from neighbouring countries, suggesting that the contribution of the Chernobyl accident and NATO bombing in 1999 to the total radioactivity in the examined areas is negligible from the health point of view (i.e. that DU ammunition was not used in these areas). © 2009 Springer-Verlag Berlin Heidelberg.

AB  - The region of the investigated receptor is situated in the southern part of the Adriatic Sea in the Mediterranean. The measuring station is located on the seashore, which, being considered as a border area, is representative for the qualitative and quantitative estimation of the influence of marine and continental aerosols on the content of major ions in precipitation. In the sampling period, precipitation in the region of the investigated receptor was more abundant during the summer and autumn than during the winter and spring. The most frequent precipitation heights were up to 20 mm, while high precipitation came exclusively from the continental region. The results of the measurements of ions readily soluble in water were used for the differentiation of marine from continental contributions of primary and secondary aerosols to their content in the precipitation. Using PCA, it was shown that main contribution of Cl-, Na+ and Mg2+ came from primary marine aerosols, while the contribution from continental sources was dominant for the content of SO42-, NO3-, NH4+ and Ca2+ in the precipitation. The continental origin of Ca2+ was from a primary source, while SO42-, NO3- and NH4+ were representatives of secondary aerosols produced by reactions between acid oxides and alkaline species in the atmosphere, but SO2- and NO3- also exist in the precipitation as free acids. The origin of the trace elements Cd, Cu, Pb and Zn in the precipitation came from anthropogenic emission sources. The results obtained in this work are based on experimental data from 609 samples collected during the period 1995-2000. (c) 2006 Elsevier B.V. All rights reserved.

AB  - For the determination of effects of contaminated crude soil on the content of trace elements in the atmospheric aerosol, trace elements in crude soil samples from within the area of influence of local resuspension were analysed. The obtained results were used for determining the contribution of local resuspension on contents of trace elements in the atmospheric aerosol using the enrichment factors (EF) method. The content of trace elements in a crude soil could arise from the geochemical background of the soil or from anthropogenic contributions. Analysis of the quantile showed that Cd, Se and Ni originate from local emission sources. PCA showed that four groups of sources contributed to the content of trace elements in PM in part of the receptor. Using EF, it was ascertained that local resuspension of crude soil particles had a dominant influence on the content of Fe, Mn and Ti in the atmospheric aerosol, and that local resuspension had no influence on the content of Se in the atmospheric aerosol. Dust originating from deserts of North Africa and Middle East, through long-range transport and through resuspension of settled dust particles, significantly contributes to the content of Fe, Mn and Ti in the atmospheric aerosol. Cd originated from contaminated crude soil. The other investigated elements originated partly from crude soil but also from some other emission sources in the region. (c) 2005 Elsevier Ltd.
