AB  - The optimized three-step sequential extraction procedure for the fractionation of micro- and macroelements, was conductedto determine fractional characteristics of PTEs (potentially toxic elements) in surface sediments of rivers in the Vlasinawatershed. The sequential extraction results, which enable the evaluation of mobility of the studied elements, have indicatedthat Zn, Ni, Cu, Cr, and As can be considered slightly mobile, whereas Pb, Mn, Cd, and Co were regarded as possibly mobileelements. 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 impacton the aquatic environment, a low percentage (0–8%) of studied toxic elements in this fraction indicated that these elementshave lithogenic origin in most sampling locations in the area of study. Except for Pb, the substantial positive correlationsbetween Al and other elements showed that studied elements came primarily from terrigenous sources. Although the valuesobtained for the risk assessment code (RAC) indicated a slightly increased mobility of some elements (up to 22.44%), thevalues of the modifed risk assessment code (mRAC), which include toxic efects on the environment, showed there is nodanger of pollution by studied elements (all values were<1%). Our recommendation is to use mRAC instead of RAC inecochemical studies and assessment of the degree of sediment and soil pollution, because mRAC includes toxic efects ofelements. Based on ATI values, river sediments show no toxic to a low toxic degree. Even though obtained results indicatethat there was no considerable risk for river water contamination, the ecological risk for Fe and Pb should be monitored inthe future.

AB  - The relationships between magnetic susceptibility (MS) and elemental variations have been the focus of considerable study in the fields of environmental assessment. The aim of this study was to apply a rapid and inexpensive, low-field magnetic susceptibility method to stream sediments from Vlasina (Serbia) and Kupa (Croatia) river basins, and discuss the relationships between MS and content of 26 studied elements using statistical approaches. 
In this research, magnetic susceptibility was measured using SM30, a small magnetic susceptibility meter with a very high sensitivity of 1 × 10-7
SI. Inductively Coupled Plasma Optical Emission Spectroscopy was used to determine the concentration of the studied elements, after sequential 
extraction procedure (Sakan et al., 2016). Total concentrations of each element were determined as the sum of concentrations determined in each fraction.
The Kupa River basin, occupies the west-central part of Croatia and is shared by two neighboring countries (Slovenia, Bosnia and Herzegovina). The Kupa itself is a tributary to the Sava River and meets the latter at Sisak after traversing a distance of 294 km. The river basin is one of the most significant water resources in Croatia (Frančišković-Bilinski et al., 2012). 
Vlasina River Basin covers an area of 1061.72 km² and covers the south eastern part of Serbia. The total length of Vlasina River is 65.9 km. The largest part of the geological base of the Vlasina River Basin belongs to the Serbo-Macedonian mass, formed in the Palaeozoic (Carbon-Perm) (Durlević et al., 2019).
Correlation analysis was performed to reveal statistical correlations between MS and 26 elements analyzed by ICP-OES in Kupa sediment samples. Ten of them showed negative correlation (As, B, Ba, Fe, K, Li, Mg, Na, P, S), while other elements showed positive. Chromium showed excellent correlation with MS (0.91) and is element with the highest correlation to MS, what could  indicate its anthropogenic origin. Element with strongest correlation to MS after Cr is vanadium (0.62), followed by Mn (0.52), Al (0.52) and Cd (0.50). All other elements have rather weak correlation with MS, among which highest are those of Sr (0.45), Zn (0.35), Be (0.28), Co (0.27), Pb (0.27) and Ti (0.26). 
Measured MS values in Vlasina samples are mostly very low, with several locations where values are a bit higher; they range from 0.02 x 10-3
to 1.113 x 10-3 SI units. The strongest correlation was observed with Mo (0.43), then with Ag (0.29). Correlations > 0.10 are determined between MS and following elements: Zn (0.17); Cu (0.12); Pb (0.17); Ba (0.13); Mn (0.10); Ti (0.20); V (0.21); In (0.16); Sn (0.16); Tm (0.10); Lu (0.12); Hg (0.16); Bi (0.13); Th (0.15) and U (0.24). Correlation analysis between MS and measured chemical elements has shown that strong correlations do not exist. 
From that it could be concluded that in Vlasina samples there is no significant anthropogenic influence.

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.

Element concentrations in the extracts were determined using ICP OES. Magnetic  susceptibility (MS) was measured using magnetic susceptibility meter. The index of geoaccumulation (Igeo) has been applied to assess trace elements distribution and contamination in studied soils. An assessment of toxic element levels in the studied soils is made by comparing the total contents of the extracted elements with the limit values determined by Serbian Regulation. Metal fractionation showed that easily mobile form is 
dominant for lead and manganese. Other elements (Zn, Ni, Cr, Co, As, Cu, Cd, and V), found dominantly in the residual fraction indicate that these elements may be an indicator for natural sources input. Obtained results indicated that the soils from Vlasina region were not contaminated with toxic elements and the origin of elements is mostly from natural processes such as soil and rock weathering.

AB  - Water-soluble inorganic ions such as ammonium, nitrate and sulfate are major components of fine aerosols in the atmosphere and are widely used in the estimation of aerosol acidity. However, different experimental practices and instrumentation may lead to uncertainties in ion concentrations. Here, an intercomparison experiment was conducted in 10 different laboratories (labs) to investigate the consistency of inorganic ion concentrations and resultant aerosol acidity estimates using the same set of aerosol filter samples. The results mostly exhibited good agreement for major ions Cl−, SO2−4, NO−3, NH+4 and K+. However, F−, Mg2+ and Ca2+ were observed with more variations across the different labs. The Aerosol Chemical Speciation Monitor (ACSM) data of nonrefractory SO2−4, NO−3 and NH+4 generally correlated very well with the filter-analysis-based data in our study, but the absolute concentrations differ by up to 42 %. Cl− from the two methods are correlated, but the concentration differ by more than a factor of 3. The analyses of certified reference materials (CRMs) generally showed a good detection accuracy (DA) of all ions in all the labs, the majority of which ranged between 90 % and 110 %. The DA was also used to correct the ion concentrations to showcase the importance of using CRMs for calibration check and quality control. Better agreements were found for Cl−, SO2−4, NO−3, NH+4 and K+ across the labs after their concentrations were corrected with DA; the coefficient of variation (CV) of Cl−, SO2−4, NO−3, NH+4 and K+ decreased by 1.7 %, 3.4 %, 3.4 %, 1.2 % and 2.6 %, respectively, after DA correction. We found that the ratio of anion to cation equivalent concentrations (AE / CE) and ion balance (anions–cations) are not good indicators for aerosol acidity estimates, as the results in different labs did not agree well with each other. In situ aerosol pH calculated from the ISORROPIA II thermodynamic equilibrium model with measured ion and ammonia concentrations showed a similar trend and good agreement across the 10 labs. Our results indicate that although there are important uncertainties in aerosol ion concentration measurements, the estimated aerosol pH from the ISORROPIA II model is more consistent.

abstract = "Water-soluble inorganic ions such as ammonium, nitrate and sulfate are major components of fine aerosols in the atmosphere and are widely used in the estimation of aerosol acidity. However, different experimental practices and instrumentation may lead to uncertainties in ion concentrations. Here, an intercomparison experiment was conducted in 10 different laboratories (labs) to investigate the consistency of inorganic ion concentrations and resultant aerosol acidity estimates using the same set of aerosol filter samples. The results mostly exhibited good agreement for major ions Cl−, SO2−4, NO−3, NH+4 and K+. However, F−, Mg2+ and Ca2+ were observed with more variations across the different labs. The Aerosol Chemical Speciation Monitor (ACSM) data of nonrefractory SO2−4, NO−3 and NH+4 generally correlated very well with the filter-analysis-based data in our study, but the absolute concentrations differ by up to 42 %. Cl− from the two methods are correlated, but the concentration differ by more than a factor of 3. The analyses of certified reference materials (CRMs) generally showed a good detection accuracy (DA) of all ions in all the labs, the majority of which ranged between 90 % and 110 %. The DA was also used to correct the ion concentrations to showcase the importance of using CRMs for calibration check and quality control. Better agreements were found for Cl−, SO2−4, NO−3, NH+4 and K+ across the labs after their concentrations were corrected with DA; the coefficient of variation (CV) of Cl−, SO2−4, NO−3, NH+4 and K+ decreased by 1.7 %, 3.4 %, 3.4 %, 1.2 % and 2.6 %, respectively, after DA correction. We found that the ratio of anion to cation equivalent concentrations (AE / CE) and ion balance (anions–cations) are not good indicators for aerosol acidity estimates, as the results in different labs did not agree well with each other. In situ aerosol pH calculated from the ISORROPIA II thermodynamic equilibrium model with measured ion and ammonia concentrations showed a similar trend and good agreement across the 10 labs. Our results indicate that although there are important uncertainties in aerosol ion concentration measurements, the estimated aerosol pH from the ISORROPIA II model is more consistent.",

AB  - Still, now the main energy production in Serbia (70%) is from low-caloric lignite of Kolubara and Kostolac basins which contain harmful elements: As, Be, Co, Mo, Mn, Ni, Pb, Se, Sb, V, U, Th, Ra, Rn etc. Six Serbian CFPPs generate about 6,000,000 t/year of ash enriched by toxic elements which are being deposited on fertile arable land and emitted in ambient air. About 1600 hectares of fertile soil is permanently contaminated with toxic elements from ash disposals endangering surface and underground waters. An increased carcinogenic risk was observed due to arsenic in ambient air, contained in

Serbia has many other possibilities for clean and low carbon energy production: 1) biogas production from biomass with which Serbia is globally one of the richest countries, 2) in summer period Serbia is country with Mediterranean climate and solar energy is easy to use, 3) Serbia is rich with underground geothermal waters that are not used for domestic and public heating, 4) energy production from methane from farms and waste disposal, 5) wind energy etc. 
The most important approach must be towards energy efficiency in the public and domestic sector and to prosumers concept. With this approach, Serbia does not need any CFPPs and especially small hydro power plants.

AB  - Geothermal hot springs are located in various tectonic environment proving environmentally friendly energy source to fulfil energy demand. The geothermal energy sources are often associated with divergent tectonic plate boundaries as in the Icelandic case or in orogeny geological settings as in the Serbian case. The chemical composition of a hot spring is a signature of the sub-surface geology and its chemical composition. Hence, the comparison of the chemical composition of geothermal sources can help us provide more detailed information prior to sub-surface exploration. In order to assess the suitability of geothermal sources we analysed the chemical composition in Icelandic and Serbian geothermal sources. For this purpose we collected samples from various hot springs in Iceland and in Serbia and analysed them using ion chromatography (IC) to determine anion concentrations and using inductively coupled plasma-optical emission spectrometry (ICP – OES) to determine cation and other element concentrations. The preliminary results reveal that chemical composition reflects differences between locations of sampling as well as the depths from which the fluid was extracted. Preliminary data obtained from the chemical analysis from sources located near to the Ocean in Iceland indicate a high concentration of Na+, K+ and Cl- ions, revealing an inflow of sea water. The data from the chemical analysis of the samples obtained from sources in Serbia, however, shows a high concentration of Na+, Ca2+ and Mg2+. These results reveal that Serbian geothermal sources are characterized by very hard water and accordingly have to be used with precaution. Further analysis of the temporal evolution of the chemical composition is advisable before sub-surface exploration.

AB  - Vlasina is a beautiful plateau in the south-east of Serbia. It is a natural protected area, known due to unspoiled nature, clean springs and Vlasina Lake, which is the largest artificial lake in Serbia, located at 1.213 m a.s.l. Vlasina River has its spring under the Vlasina Lake dam and it is about 70 km long tributary of South Morava River. Because of its location in a sparsely inhabited mountain region and because of lack of industrial pollutants in this area, Vlasina is considered to be one of the cleanest Serbian rivers.
We aim to introduce the relatively new, fast and cheap method of magnetic susceptibility (MS) in environmental research in Serbia, in addition to usually used geochemical and mineralogical methods. Until recently MS measurements have not been used for this purpose in the broader region around Serbia, e.g. first such measurements in Croatia were performed by Francišković-Bilinski (2008) on the samples from Kupa River watershed. ´
Measured MS values in Vlasina samples are mostly very low, with several locations where values are a bit higher; they range from 0.02 x 10-3 to 1.113 x 10-3 SI units.
Statistical boxplot analysis of anomalies has shown that 3 extremes (anomalies of higher degree) and 1 outlier (anomaly of lower degree) exist.
Correlation analysis between MS and measured chemical elements has shown that strong correlations do not exist. From that it could be concluded that in Vlasina samples there is no significant anthropogenic influence. In the case of Vlasina strongest correlation was observed with Mo (0.43), then with Ag (0.29). Correlations > 0.10 are determined between MS and following elements: Zn (0.17); Cu (0.12); Pb (0.17); Ba (0.13); Mn (0.10); Ti (0.20); V (0.21); In (0.16); Sn (0.16); Tm (0.10); Lu (0.12); Hg (0.16); Bi (0.13); Th (0.15) and U (0.24). Those correlations support our hypothesis about natural (geogene) origin of those elements from metamorphic rocks,
which prevail in this region.
Q-mode cluster analysis was also performed. It also supports our claim that in Vlasina region there is no significant anthropogenic influence. Cluster 1 from Vlasina is correlated with carbonates, as mean Ca value in this cluster is 8 times higher than in Cluster 2. Cluster 1 contains samples from 4 locations, which are located in the area where carbonate rocks (mainly limestones) are present. On those locations also statistical anomalies of Ca were found using boxplot method. In this carbonate cluster concentrations of majority of heavy metals are lower than in Cluster 2, also MS value is lower, what is due to the fact that in carbonates metal concentrations are naturally lower.

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.

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) >= 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.

AB  - Size-segregated urban aerosol of Belgrade center (44049'14''N, 20027'44''E) was studied during the summer-autumn 2008. The representative location in traffic area Studentski trg was chosen for investigating physical and chemical characteristics of collected particles. Particle size distribution in the size range Dp = 0.49 m, 0.49 = Dp = 0.95 m, 0.95 = Dp = 1.5 m, 1.5 = Dp = 3.0 m, 3.0 = Dp = 7.2 m and Dp = 7.2 m were measured. Aerosol samples were submitted to gravimetric SEM analysis. The shape, size and chemical composition of the fine and coarse particles were analyzed. The imaging was carried out by SEM (Nova NanoSEM 230, FEI, USA). The same SEM was also used for the EDX measurements performed. The particles collected on fiber filters for SEM imaging were further on coated with 4 nm Pt layer to improve conductivity of the samples. The morphological and chemical composition suggested that the most abundant particles were carbonaceous soot but also microbes and natural and anthropogenic inorganic mineral materials. The chemical characterization was performed on a semi-quantitative level. The contents of the carbon were up to 70% or higher. In the samples were dominating next others elements: O, Mo, Si, Fe, Ca, Al, K, Mg.

AB  - In order to examine association patterns and pollution potential of trace and major elements from coal ash, six composite samples of fresh, filter fly, and aged dump coal ash from "Kostolac A" power plant located 100 km from Belgrade, the Serbian capital, were subjected to the sequential extraction procedure. Five extractants were applied (in the following order): distilled water, 1 M ammonium acetate, 0.2 M ammonium oxalate/0.2 M oxalic acid, an acidic solution of H(2)O(2), and 6 M HCl. Obtained concentrations were statistically analyzed and associations of trace and major elements were established.

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).

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 SO42− 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.

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.

AB  - We applied statistical methods to the data of a 5-year sampling period to characterize the features of trace elements in airborne particulate matter at the South Adriatic Coast. The analysis of surface soil samples was also performed. The data were processed by cluster analysis, enrichment factor determination and receptor rose statistics. It is shown that the principal element association consists of Fe, Mn and Ti originating from surface material resuspension. Hg and Se were shown to originate from more complex natural and anthropogenic processes. A strong emission source of Cd and Se was identified in the SSE direction.
