AB  - In order to further define the potential use of FTIR-ATR spectroscopy, as a non-destructive and reliable technique, for the analysis of the characteristics of post stamps, certified originals of the Principality of Serbia stamps (“Prince Michael issues”) issued in 1866 and 1868 as well as their forgeries were ana­lyzed. Spectra enabling the comparison of the paper, dye and glue of stamps of so-called “Vienna issues”, having denominations of 10 (orange-yellow), 20 (pink) and 40 para (blue) and “Belgrade issues” (1 para-green and 2 para-reddish brown), as well as 24 expert-certified forgeries, were taken. It was shown that the applied technology was, in most of the cases, a fast and suitable technique for establishing clear differences between the spectral characteristics of the paper and dye used for the original stamps, and forgeries that were most probably made decades after the printing of the genuine stamps. The differences between print­ings of the same issues of the genuine stamps were also elaborated. It is pro­posed, for the first time in philatelic history, the possibility that “Vienna issues” stamps may have been printed on two different papers, and, having in mind the technology of printing in the 19th century, potentially, not even at the same time or in the same printing house.

AB  - The phenolic and elemental profiles of Serbian autochthonous grape varieties ‘Smederevka’ and ‘Plovdina’ were studied and compared with some international varieties. Total phenolic content and radical scavenging activity were highest in seeds of ‘Plovdina’, and in ‘Smederevka’ skins, which also had the highest contents of ferulic, chlorogenic and caffeic acids (16.0, 1.44 and 0.98 mg/kg, respectively). Protocatechuic acid was quantified only in the seeds of these varieties. Untypically for Vitis vinifera L. species, the presence of malvidin 3,5-O-dihexoside was found in the skins of ‘Vranac’ and ‘Muscat Hamburg’. In ‘Plovdina’ skins among the anthocyanins, hexosides of peonidin and delphinidin were prevalent. ‘Plovdina’ grapes had lower quantities of Al, Ni and Na in comparison to the other varieties intended for white wine production. Significant correlations among the most abundant elements, such as K, P, Ca, Mg, S, Fe, Cu, and Zn, pointed to potential positive interactions. For elements that have toxicological reference values, the health risk assessment was calculated for adults and children, and suggested that all samples were safe for human consumption.

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 
the respiratory particles of the finest fraction. CFPPs are identified as their emission sources. In recent years, small hydropower plants have been installed on last mountains clean rivers in Serbia based on decades old echnical projects and old water data, which do not include the climate change factors. Our research has shown the consequence on Vlasina River, making it the swamp quality water and enhanced erosion processes. 
Particularly dangerous in mountainous areas is of landslides and torrential floods induced by enormous precipitation due to climate change. Problems of the water supply of Vlasotince municipality are already evident. 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  - The pollution state and health risk assessment of potentially toxic elements (PTE) in soil and sediment samples of the petrochemical industry and its surrounding area are evaluated in this study. The pseudo-total contents of Ba, Cd, Co, Cu, Cr, Mn, Ni, Pb, V, Zn, As, Hg, and Se were measured by inductively coupled plasma–optical emission spectrometry (ICP/OES) in analyzed samples. Instead of determining total content, we performed aqua regia of the samples. The silicate matrix remained, and the quantities of elements that are within the silicate matrix do not represent an environmental danger. The soils from the chlor–alkali plant are highly polluted by Hg (the enrichment factor values were above 6000), and by Cu, Cd, Pb, and Zn, while the sediment samples from the wastewater channel are polluted with Cr, Cd, and Hg. The measured element contents are used for calculating health risk criteria for a composite worker (a worker who is exposed, long-term, during the work day) and for residential people. Hg is the element that mainly contributes to non-carcinogenic risks within the petrochemical area. The highest value of total carcinogenic risk obtained in the sediment sample from the wastewater channel, and the metal that mostly contributes is Cr. The areas closest to the petrochemical industry have higher values of health risk criteria parameters and pollution indices. The areas that are located further to the north and south from the petrochemical industry are less burdened with the analyzed elements, which is significant because the closest city and village are situated in those directions.

AB  - A total of 138 samples of canned tuna, sardines and mackerel from the Serbian market were analyzed for toxic (As, Cd, Pb, Hg) element levels using ICPMS. The highest average contents of toxic elements were found to be 1.70 mg kg(-1) for arsenic and 0.026 mg kg(-1) for cadmium in sardine and 0.068 mg kg(-1) for mercury in tuna. The lead content was very similar (similar to 0.048 mg kg(-1)) of the three types of canned fish. None of the fish analyzed contained toxic elements in levels exceeding the maximum allowable levels currently in force. Human health risk assessment of As, Cd, Pb and Hg in canned fish were investigated. A risk assessment based on the measured levels of examined elements indicated that consumption of canned fish according to current eating habits in Serbia presents little risk to human health since the carcinogenic risk is within the acceptable range, 10(-4)-10(-6).

AB  - This study aims to compare three extraction techniques of four sequential element extraction steps from soil and sediment samples that were taken from the location of the Pancevo petrochemical industry (Serbia). Elements were extracted using three different techniques: conventional, microwave and ultrasound extraction. A novel procedure sum of the ranking differences (SRD) - was able to rank the techniques and elements, to see whether this method is a suitable tool to reveal the similarities and dissimilarities in element extraction techniques, provided that a proper ranking reference is available. The concentrations of the following elements Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Si, Sn, Sr, V and Zn were determined through ICP OES. The different efficiencies and recovery values of element concentrations using each of the three extraction techniques were examined by the CRM BCR-701. By using SRD, we obtained a better separation between the different extraction techniques and steps when we rank their differences among the samples while lower separation was obtained according to analysed elements. Appling this method for ordering the elements could be useful for three purposes: (i) to find possible associations among the elements; (ii) to find possible elements that have outlier concentrations or (iii) detect differences in geochemical origin or behaviour of elements. Cross-validation of the SRD values in combination with cluster and principal component analysis revealed the same groups of extraction steps and techniques.

AB  - This study aims to compare three extraction techniques of four sequential element extraction steps from soil and sediment samples that were taken from the location of the Pancevo petrochemical industry (Serbia). Elements were extracted using three different techniques: conventional, microwave and ultrasound extraction. A novel procedure sum of the ranking differences (SRD) - was able to rank the techniques and elements, to see whether this method is a suitable tool to reveal the similarities and dissimilarities in element extraction techniques, provided that a proper ranking reference is available. The concentrations of the following elements Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Si, Sn, Sr, V and Zn were determined through ICP OES. The different efficiencies and recovery values of element concentrations using each of the three extraction techniques were examined by the CRM BCR-701. By using SRD, we obtained a better separation between the different extraction techniques and steps when we rank their differences among the samples while lower separation was obtained according to analysed elements.

AB  - A total of 138 samples of canned tuna, sardines and mackerel from the Serbian market were analyzed for toxic (As, Cd, Pb, Hg) element levels using ICPMS. The highest average contents of toxic elements were found to be 1.70 mg kg(-1) for arsenic and 0.026 mg kg(-1) for cadmium in sardine and 0.068 mg kg(-1) for mercury in tuna. The lead content was very similar (similar to 0.048 mg kg(-1)) of the three types of canned fish. None of the fish analyzed contained toxic elements in levels exceeding the maximum allowable levels currently in force. Human health risk assessment of As, Cd, Pb and Hg in canned fish were investigated. A risk assessment based on the measured levels of examined elements indicated that consumption of canned fish according to current eating habits in Serbia presents little risk to human health since the carcinogenic risk is within the acceptable range, 10(-4)-10(-6).

AB  - This study assessed the state of waters in Belgrade regarding pollution with musk compounds as the target contaminants. Eleven of these compounds were alicyclic, two were macrocyclic, and one was polycyclic. Solid-phase microextraction was used for the isolation of these compounds from waste, surface and underground waters and from processed water prepared for drinking, while comprehensive orthogonal two-dimensional gas chromatography with mass spectrometry was used as the final analytical method. In wastewater samples, galaxolide was detected in concentrations of 1.13 and 0.40 mu g/L, while in the Sava River and underground water its concentrations were 0.09 and 0.038 mu g/L. The lowest concentrations of the investigated musk compounds were detected in underground water samples, indicating that this is the cleanest water of all the analyzed sources with respect to musk compounds. Comparing the results of musk compound concentrations determined in surface river water samples and clean river water samples utilized for drinking, a lower concentration of these compounds was detected in the clean river water samples. The majority of musk compounds were found in waters utilized for drinking. Based on the concentration values, we conclude that the analyzed waters are moderately polluted with these compounds.

AB  - This research was designed to determine phenolics content, radical scavenging activity and mineral composition of 22 grapevine leaves of diverse varietal origin. Samples were collected from two vineyards located in Central Serbia (Belgrade vineyard area) and Eastern Serbia (Mlava vineyard area). Leaf extracts were characterized mostly with phenolics acids, flavonols and flavan-3-ols. Ellagic acid and rutin were the most abundant components, found in the concentration up to 770 mg/kg and 450 mg/kg of dry weight, respectively. Total phenolic content was in the range from 27.5 to 76.0 g GAE/kg of dry weight while the radical scavenging activity ranged from 0.429 to 0.867 mmol TE/kg of dry weight. The most common element in all samples was IC (content ranging from 2.30 g/kg to 6.77 g/kg of dry weight), followed by Ca, Na, and B. A variation in the chemical composition was shown to be convenient way to differentiate among the grape leaves of diverse varietal origin. Clear separation was demonstrated between objects of different geographical origin by Principal Component Analysis. Serbian variety 'Petra', an interspecies hybrid with atypical composition, was detected as an outlier in comparison to other samples.

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  - To effectively manage potential environmental and human health impacts of contaminated river sediments, it is important that information about the source (anthropogenic vs geogenic), variability and environmental risks associated with the contamination are well understood. The present study was carried out to assess the source and severity of contamination and to undertake a risk assessment for selected elements (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, V and Zn) in river sediments in Serbia. The estimate of the anthropogenic component of contamination was derived by determining the total element content and the background values for elements in sediments, and the severity of pollution was assessed by calculating a number of pollution indices including the contamination factor, the enrichment factor, the index of geoaccumulation, the ecological risk factor, the potential ecological risk index, the pollution load index, the combined pollution index, the modified degree of contamination and the toxic unit factor. This analysis indicates that river sediments in Serbia are primarily polluted with Zn, Cu and Cd. The most contaminated river systems are the Ibar, Pek, West Morava and Great Morava rivers. Mining activities were found to have a significant influence on sediment. Multivariate analyses suggested anthropogenic origins for Pb, Zn, Cd, As, Ni and Cu, whilst Fe, V, Mn, Co and Cr appear to have a mixed origin (both lithogenic and anthropogenic sources). A geochemical approach, with a calculation of pollution indices and statistical methods, is recognised as useful for the risk management of trace elements in sediments around the world.

AB  - In the present study, concentrations of heavy metals (Cd, Cu, Co, Mn, Cr, Ni, Pb, and Zn) were determined at 35 river sediments in Serbia. The anthropogenic heavy metals input and quantification of the metal enrichment degree in sediments were estimated by calculating geo-accumulation indices (I-geo) and enrichment factors (EF). These pollution indices have been calculated using different background values (continental crust and local background values) and different element used for normalization (Al and Fe), followed by result comparison. The EF values calculated with continental crust as background (minor to extremely severe enrichment) were higher than when regional background values were used (minor to moderate enrichment). Significant influence of background values on the I-geo values is observed. Values of geo-accumulation index ( LT 2) revealed that studied river sediments are remaining unpolluted to moderately polluted with Co, Mn, Cr, and Ni. Significant pollution in the sediments was observed for Cd, Cu, Pb, and Zn elements. The results of this study confirm the relevance of precise and accurate determining of local background concentrations while assessing sediment pollution. The values of EFs for studied elements were more influenced by the choice of background values than selection of element used for normalization. Our recommendation would be to use the local and regional background content in quantification of metal contamination in sediments, since these values differ and are site and region dependent.

AB  - The purpose of this study was to evaluate sediment heavy metals (Cd, Cu, Co, Mn, Cr, Ni, Pb and Zn) related to pollution in freshwater sediments in Serbia. The heavy metal enrichment determination in studied sediments was conducted by using total metal content with strong acidic digestion (HCl + HNO3 + HF), a calculated enrichment factor (EF), and application of correlation analysis and the box plot method. For identification of appropriate elemental normalisers for enrichment factor calculations, Fe, Al, Ti and Si were used. The significant variation in heavy metal distribution among samples collected in this large region, encompassing all Serbian watersheds, suggests the selective contamination of sediments by heavy metals. Values for EF indicate nil to moderate enrichment for most studied elements, except for Cd, Cu, and Zn at some sampling points, where the enrichment was, in some cases, even severe. The high content of heavy metals and EFs in Serbia is related to the human activities around the sampling sites. The results indicate that all elements used for normalisation in this paper can also be used to estimate the anthropogenic influence, with an exception of Co, which should be considered as an element for normalisation in future studies.

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  - In this paper, the main objective was fractionation of Cd, Cu, Ni, Pb, Zn, Ca, Fe, and K in certificate material and sediment samples gathered from and around the Petrochemical Industry using the conventional, microwave and ultrasonic sequential extraction. Microwave oven and ultrasound bath were used as an energy source for achieving faster extraction. Additional heating and boiling of samples were avoided by using lower power and shorter time for microwave and ultrasound extraction. Precision and accuracy of procedure were evaluated by using certificate material (BCR701). Acceptable accuracy of metals (87.0-111.3 %) was achieved for all three-step sequential of conventional extraction protocol. An accuracy of the fourth step has been verified with two certificate materials: BCR143R and 146R. The range of total extracted metal concentrations from sediments was similar for all three extraction techniques. A significant high percentage of Cd, Cu, and Zn were obtained after extraction of the exchangeable and acid soluble sediment fraction. Principal component analysis of values obtained after determination of risk assessment code using conventional and ultrasound sequential extraction show similarity of these values. Accuracy, recovery, and risk assessment code values imply that ultrasound sequential extraction is a more suitable, accelerated sequential extraction procedure (30 min per extraction step) than microwave extraction in applied conditions.

AB  - Serbia obtains most of its energy from low-quality lignite, thus being one of the world's largest producers of coal ash per capita. In order to examine the distribution of trace and major elements in the ash and the pollution potential of the ash itself, six combined samples of filter ash, obtained by lignite combustion in the Nikola Tesla A Power Plant, were subjected to a five-phase sequential extraction. Analysis of obtained concentrations revealed the short- and long-term pollution capacity of different elements as well as the influence ionic strength of river water may have to the pollution of neighboring waters.

AB  - We use conventional, microwave and ultrasound assisted sequential extraction, of defined time and power, techniques for extractions of Cd, Cu, Cr, Ni, Pb and Zn in sediments and certified material. We did not change the conditions of extractions through steps, cause we what to see is there difference in extraction results for the certified material and sediments. We use lower powers and time from microwave and ultrasound extraction in order to avoid additional heating and boiling of the samples. Steps 1-3 of the BCR (Community Bureau of Reference), excluding the hydrogen peroxide digestion in step 3, were completed in 16 h in the conventional, in 120 s with 90 W power of microwave and in 30 min of 42 kHz of an ultrasonic frequency. Digestion of organic matter with hydrogen peroxide was performed the same for all techniques. The fourth step, the pseudo-total content, was performed the same on samples remaining after performing the extraction of the previous three phases either conventionally, microwave-assisted or with ultrasound. The precision and accuracy of the proposed procedures were evaluated using a certified reference material BCR701. Acceptable accuracy for most of the metals was observed for all three steps of BCR protocol applying a 16 h total shaking period. Metals were determined with an acceptable accuracy after the pseudo-total step; expect Cr. Results obtained after the application of different techniques on sediments were comparable with ANOVA test for the 95 % of confidence level.

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 Dp ≤0.49 μm, 0.49 ≤ Dp ≤0.95 μm, 0.95 ≤ Dp ≤1.5 μm, 1.5 ≤ Dp ≤3.0 μm, 3.0 ≤ Dp ≤7.2 μm and Dp ≥ 7.2 μm 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 (mGM) 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) >= 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.
