AB  - The influence of extraction parameters on the ultrasonically assisted extraction (UAE) of K, Na, Ca, Mg, Zn, Cu, Fe, Mn, Cr, Se, Mo, Li, Al, B, Pb, Hg, Cd, As, and Ni was studied to determine the conditions when a minimum of essential and maximum of toxic elements is leached from peppers, depending on its ripening stage. The effect of process variables was investigated by using Box–Behnken design. Each essential element had a different optimal condition for minimal leaching, while the toxic elements were predominantly extracted with acetic acid solution as extractant. The highest correlation between extraction conditions and concentration of extracted elements was found for aqueous extracts of mature green pepper. The concentration of acetic acid highly influenced the leaching of elements and a strong correlation between the concentration of Al, B, Fe, and Mn, and the UAE experimental conditions were observed. Practical applications: This study investigates the leaching of minerals and heavy metals present in vegetables to the most commonly used media (water and acetic acid) during processing and canning. The data from this study may be useful for improving the quality of processed pepper products due to new information on how different parameters influence these losses (ripening stage of peppers, medium/solvent used for preparation, or storage, applied temperatures, time, mass to volume ratio). Essential elements are better preserved during the processing of intermediate breaker and mature red pepper compared to green mature fruits. Better retention of essential elements in the breaker and mature red pepper (that are mostly used in industrial processing) can be achieved by reducing the contact time with water, as well as mass to volume ratio. Leaching of toxic elements Al, Hg, and As can be improved with an acetic acid solution.

AB  - The phenolic compounds, which are rich in red wine, have gained considerable attention due to their antioxidant potential. Selected Serbian wines were analyzed for their antioxidant activity by DPPH test and the total content of phenolic compounds was determined by employing the Folin–Ciocalteu colorimetric method. The major polyphenols were determined by HPLC. The antioxidant activity was correlated with the amount of specific polyphenols (gallic acid, caffeic acid, catechin, epicatechin, myricetin, and kaempferol) by quantitative structure–activity relationship. The origin of the antioxidant potential of wines was discussed based on the individual activity of identified polyphenols and theoretical calculations (at APFD/6-311++G(d,p) level of theory). The thermodynamic parameters of free radical scavenging activity and reactivity towards DPPH·, HO·, and HOO· were explained with special emphasis on the effect of structure and intramolecular interactions in polyphenols. Based on the presented data, the positive effects of selected Serbian wines on humane health and biologically relevant free radicals are concluded.

AB  - Many pollution sources are difficult to identify because pollutants are transported far away into complex environments. In particular, the mechanisms of petroleum migration in sediments are poorly known. Here, we studied two sediments from the circuit of a heating plant and three sediments located at 100, 200 and 300 m away from the plant. Saturated hydrocarbons were isolated and group composition was determined by column chromatography. n-Alkanes, terpanes and steranes were analyzed by gas chromatography-mass spectrometry. Results show that the amount of short n-alkanes increases during migration, which indicates the migration mechanism. Results on steranes reveal a geochromatographic migration of the oil, where the fastest eluting stereoisomers display the longest migration path. Changes in the distribution of biological markers are explained by migration in water.

AB  - A direct current (DC) polarographic assay based on the decrease of anodic current of HydroxoPerhydroxoMercury (II) Complex (HPMC) formation in H2O2 solution in Clark Lubs (CL) buffer (pH 9.8) as working solution was previously applied to determine antioxidant (AO) capacity of water-soluble compounds. Here, the applicability of HPMC assay was extended into samples poorly soluble in water such as the essential oils and extracts of Lamiaceae and Apiaceae species obtained by ultrasound-assisted maceration (UAM) and Soxhlet extraction (SE) with 70 and 96% ethanol as well as individual compounds present. The influence of solvents miscible with water on HPMC anodic current was studied, and working solution was optimized. A modified HPMC method was applied to measure AO capacity of essential oils and extracts as well as compounds identified using gas chromatography-mass spectrometer (GC-MS) and gas chromatography with flame-ionization detection (GC-FID) (terpenoids and catechols) or known to be present (phenolic acids and flavonoids). A 1:1 mixture of CL buffer and ethanol was chosen as working solution. AO capacity of essential oils and extracts, established by modified HPMC assay, was in range of 1.2-2.0 and 9.2-38.4 (%/mL) while terpenoids and phenolics in range of 0.1-0.5 and 13.5-38.5 (%/mol), respectively. The superior AO capacity was ascribed to essential oils and extracts of Lamiaceae species and to extracts obtained with 70% ethanol. A higher AO capacity of extracts in comparison to essential oils was corroborated with a difference in phenolics and terpenoids capacity.

AB  - Basil essential oil (BEO) contains a wide range of chemical compounds whose content may vary depending on chemotypes, environmental conditions, agronomic techniques and particularly the origin of the plant. In our present study, essential oils (EOs) were isolated by hydrodistillation method from dry herbs of three basil cultivars and analyzed by GC-FID and GC-MS. Two of the tested cultivars belong to sweet basil group (B-1 and B-2) while the third one was large leafed 'Genovese' basil (B-3). EO content in the dry herb was 0.65%, 0.41% and 0.62% respectively. The main classes of compounds of B1EO and B3EO were sesquiterpene hydrocarbons (38.39% and 37.95%), oxygenated monoterpenes (25.44% and 28.04%) and phenylpropanoids (17.43% and 15.71%). The main constituents of both EOs were monoterpene alcohol linalool (13.68% and 15.38%), phenoyl derivate eugenol (10.83% and 8.97%) and sesquiterpene hydrocarbon alpha-bergamotene (8.12% and 9.25%). In both EOs, epi-bicyclosesquiphellandrene was detected in considerable amount (7.03% and 8.07%). The most abundant compound classes in B2EO were oxygenated monoterpenes (52.07%), sesquiterpene hydrocarbons (24.27%) and phenylpropanoids (10.95%). Linalool was the dominant compound (40.97%), followed by epi-bicyclosesquiphellandrene (8.70%) and methyl chavicol (7.92%). The results showed complex chemical composition of BEOs and pointed out the presence of biologically active compounds of importance for different branches of the pharmaceutical, chemical and food industry. Although there are differences in the chemical composition of the BEOs, the obtained results show that all of the tested cultivars are rich in compounds which are responsible for biological activities.

AB  - Herbal liqueurs are spirits with numerous functional properties, due to the presence of bioactive extractable compounds deriving from herbs. The aim of this study was to obtain new herbal bitter liqueur (HBL) on the basis of twelve selected bitter and aromatic plants extracts, with an optimal sensory profile for consumer acceptance. Also, the determination of optimal sugar content in HBL was done. Furthermore, antioxidant (AO) capacity and total phenolic content (TPC) of HBL was evaluated and compared to similar commercial herbal spirits. Among five tested formulations, assessed by 9-point hedonic scale, HBL with the ratio of bitter and aromatic plants 1:4 was the most acceptable. Ideal concentration of sugar in HBL, determined using a just-about-right scale, was found to be 80.32 g/l of sucrose, which is approximately 20% less than the minimum stipulated by European Union Regulation and several times lower than in the majority of commercial liqueurs. Obtained result indicates the possibility of sugar reduction in liqueurs, and suggests the need to carry out sensory analysis before production of these high-calorie beverages. Radical scavenging ability against DPPH and ABTS radicals, as well as ferric reducing antioxidant power and TPC of HBL were convincingly superior in comparison to similar commercial herbal alcoholic beverages. High correlation coefficients between TPC and other assays applied strongly support the significant role of the polyphenols in the total AO capacity of the HBL and other tested commercial herbal spirits. Headspace GC/MS revealed that the most abundant terpenes were menthone (3.75%), eucalyptol (3.42%) and menthol (3.10%), whereas methanol was present in a small amount (4.97 mg/l).

AB  - Grape skins (GS), which can be considered as reusable coproducts of winemaking, were processed to develop semiliquid ingredients for functional foods, as an alternative to powdered GS, which needs high energy input for drying. Processing of semiliquid GS ingredients included blanching, dilution to obtain dispersions with 2% or 10% of dry solids, milling, homogenization, and pasteurization. The individual phenolic contents and in vitro ferric ion reducing capacity (FRAP) of semiliquid GS ingredients were compared with those of air-dried and freeze-dried GS. With respect to freeze-dried GS, the recovery of FRAP values was similar to 75% for both air-dried GS and 2% GS dispersion and 59% for 10% GS dispersion. The average particle size diameters of solids in semiliquid GS ingredients were similar to those observed in commercial apple skin products. Possible applications of GS semiliquid ingredients to increase the reducing capacity of food 10 times include formulation into beverages and ice-type desserts and use in bakery products.

AB  - In this paper, an attempt was made to contribute to the use of biological markers, n-alkanes, and polycyclic alkanes of the sterane and terpane type, in the assessment of the source of oil pollutants in the environment using the example of the correlation between recent river and coastal sediments,. Four samples of recent river sediments of the Vrbas River and four samples of adjacent bank sediments (soils), in the part of the River that belongs to the city of Banja Luka (Bosnia and Herzegovina) were analyzed. In the alkane fractions of isolated extracts, a bimodal distribution of the n-alkanes was observed. Lower homologues dominated in the recent river sediments with maximum at C15, but higher n-alkanes dominated in the soil samples, with a maximum at n-C29 or at n-C31. The higher concentration of steranes and terpanes with oil type distributions in the recent/fresh river sediments (compared to the bank sediments) represents evidence that lower n-alkanes originate from oil sources. The higher content of total hydrocarbons in the recent river sediments than in the bank sediments further confirms this conclusion. At the same time, these fundamental considerations provide evidence that oil pollution primarily occurred in the water flow and then the oil pollutants propagated towards the riverbank.

AB  - A series of alpha,omega-telechelic polydimethylsiloxanes (PDMS), with predetermined molecular weights of about 2500 g mol(-1), was synthesized by siloxane equilibration reaction. Syntheses were performed using octamethylcyclotetrasiloxane (D-4) and various disiloxanes: hexamethyldisiloxane (HMDS), 1,1,3,3-tetramethyldisiloxane (TMDS), 1,3-divinyltetramethyldisiloxane (DVTMDS), 1,3-bis(3-carboxypropyl) tetramethyldisiloxane (DCPTMDS) and 1,3-bis(3-aminopropyl) tetramethyldisiloxane (DAPTMDS). The role of the disiloxane was to introduce terminal functional groups at the end of the polymer chains and to control the molecular weight of the polymers. Polymers with trimethyl, hydrido, vinyl, carboxypropyl and aminopropyl end-groups were obtained in this way. The structure of the alpha,omega-telechelic PDMSs was confirmed by NMR and IR spectroscopy. The molecular weights of the polymers were determined by H-1-NMR, gel permeation chromatography (GPC) and dilute solution viscometry. Thermogravimetric analysis (TGA) under nitrogen and air showed that the type of the terminal groups significantly influenced the thermal and thermo-oxidative stability, as well as the degradation mechanism of the alpha,omega-telechelic PDMSs.

AB  - Three different techniques were applied for the aqueous extraction of anions from coal and fly ash: rotary mixer-and ultrasonic-assisted extraction with different duration time, and microwave-assisted extraction at different temperatures. Validation showed that the ion-chromatographic method was suitable for the analysis of anions in coal and fly ash extracts. The variations in the amounts of anions using different extraction times during rotary-assisted extraction were minimal for all investigated anions. The efficiency of ultrasound-assisted extraction of anions from coal depended on the sonication time and was highest at 30 min. The ultrasound-assisted extraction was less efficient for the extraction of anions from fly ash than rotary-assisted extraction. Increase of temperature in the microwave-assisted extraction had a positive effect on the amounts of all anions extracted from coal and sulphate from fly ash, while the amounts of fluoride and chloride in fly ash extracts decreased. The microwave-assisted extraction of coal at 150 degrees C was compared with standard ASTM methods, and results were in good agreement only for chloride. Changes in the pH value and conductivity during ultrasound-assisted extraction were measured in order to explain changes on the surface of coal particles in contact with water and different processes that occur under environmental conditions.

AB  - The aim of this paper is to simulate leaching of metals from fly ash in different environmental conditions using ultrasound and microwave-assisted extraction techniques. Single-agent extraction and sequential extraction procedures were used to determine the levels of different metals leaching. The concentration of metals (Al, Fe, Mn, Cd, Co, Cr, Ni, Pb, Cu, As and Be) in fly ash extracts were measured by inductively coupled plasma-atomic emission spectrometry. Single-agent extractions of metals were conducted at sonication times of 10, 20, 30, 40 and 50 min. Single-agent extraction with deionized water was also performed by exposing samples to microwave radiation at temperature of 50 degrees C. The sequential extraction was conducted according to the BCR procedure which was modified and applied to study the partitioning of metals in coal fly ash. The microwave-assisted sequential extraction was performed at different extraction temperatures: 50, 100 and 150 degrees C. The partitioning of metals between the individual fractions was investigated and discussed. The efficiency of the extraction process for each step was examined. In addition, the results of the microwave-assisted sequential extraction are compared to the results obtained by standard ASTM method. The mobility of most elements contained in the fly ash is markedly pH sensitive.

AB  - This paper presents the extraction of major and trace elements from a coal sample, in deionized water, by using three different extraction techniques. Rotary mixing and ultrasonic extraction were examined for different extraction times, while the microwave-assisted extraction was performed at different temperatures. Metal concentrations (Na, K, Ca, Mg, Al, Fe, Mn, Be, Cd, Co, Cr, Hg, As, Ni, Se, Sb and Pb) in solution were determined employing inductively coupled plasma atomic emission spectrometry; whereas the results obtained for Na, K, Ca and Mg were compared employing ion chromatography. Comparing the rotary-and ultrasonic-assisted extractions, it was shown that the former technique was more efficient for the determination of Fe, Na and Pb, whereas the latter one proved more efficient for the determination of Co and Cr ions. Microwave-assisted extraction was shown to be the most efficient method for all the tested elements in coal. In addition, sequential extraction of the elements was realized using microwave digestion. The results of the sequential extraction experiments indicated associations of investigated elements with a mineral phase and organic matrix. Sequential extraction provided information on possible leaching of As, Cd, Co, Cr, Ni, Pb, Fe and Mn under environmental conditions.

AB  - Antioxidant (AO) capacity of various medicinal plants extracts and phenolic compounds was assessed by the most widely used spectrophotometric assays such as ferric reducing antioxidant power (FRAP) and scavenging of 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH). In addition, two direct current (DC) polarographic assays, one based on a decrease of anodic current of [Hg(O2H)(OH)]-HydroxoPerhydroxoMercury(II) Complex (HPMC) formation in alkaline solution of H2O2, at the potential of mercury dissolution and another recently developed Mercury Reduction Antioxidant Power (MRAP), based on a a decrease of cathodic current of Hg(II) reduction were employed. Percentage of both currents decrease was plotted versus the volume of gradually added complex samples or the amount of individual ones and the slopes of these plots were used to express AO capacity. Total phenolic content (TPC) of extracts was determined by Folin-Ciocalteu (FC) assay. Correlations between applied assays were calculated by regression analysis. Relative Antioxidant Capacity Index (RACI), calculated by assigning equal weight to all applied assays and Phenolic Antioxidant Coefficients (PAC), calculated as a ratio between particular AO capacity and TPC, were used to achieve more comprehensive comparison between analyzed samples, as well as applied assays.

AB  - Direct current (DC) polarographic antioxidant (AO) HPMC assay based on the decrease of anodic limiting current of [Hg(O2H)(OH)] (HydroxoPerhydroxoMercury(II) Complex-HPMC), formed in alkaline solution of H2O2, at potential of mercury oxidation, occurring upon AO addition, was validated and widely used recently. Here, a novel DC polarographic assay, MRAP (Mercury Reduction Antioxidant Power), based on the decrease of Hg2+ cathodic current with addition of AOs was applied. Percentage of this decrease was plotted versus the amount of various individual phenolics or the volume of medicinal plant extracts, and the slope obtained was used to express AO activity. A high correlation between MRAP and HPMC assays was found for individual compounds (r = 0.974) and real samples (r = 0.968). MRAP was shown to be effective in the determination of AO activity of both synthetic mixtures of individual AOs and real samples containing various AOs. Agreement between the decrease of Hg2+ cathodic current and HPMC anodic current lead to the assumption that Hg2+ reduction causes a decrease in concentration of Hg2+ available for HMPC complex formation, i.e. its anodic current decrease. The validity Of MRAP assay was also confirmed through good correlation with FRAP assay.

AB  - Three different synthetic polymers commonly used in drilling fluids (carboxymethyl cellulose - CMC, hydroxyethyl cellulose - HEC and polyacrylamide - PAA) were analysed by off-line-pyrolysis-gas chromatography-mass spectrometry (off-line-Py-GC-MS). The aim of this study was to determine specific environmental marker compounds for the identification of contamination due to drilling activities. In a first step, reference materials of the main constituents of commonly applied water-based drilling fluids were purchased and analysed to identify potential indicator substances. For each polymer a set of two to three specific pyrolysis products was determined. Afterwards, four CMC, one HEC and two PAA based drilling fluids were pyrolysed in order to retrieve the previously identified compounds in drilling fluid mixtures. All indicator compounds were identified. In a third step, spiking experiments on drill cutting samples of various depths of one well proved the traceability of the applied polymers and verified the applicability of the indicator systems in terms of sensitivity and specificity.

AB  - The goal of this work was to investigate the relationship between antioxidants' content and the oxidative stabilities of grape seed oils obtained from the Cabernet Sauvignon variety. The samples of grape seed oils were obtained by ultrasound assisted extraction. The time of extraction was varied, while the other relevant parameters: extraction temperature, solvent to solid ratio and sonication power were kept constant. For the sake of comparison, the extraction was also done using the conventional Soxhlet method. For all the oil samples obtained, the contents of total phenolic compounds (TPC), alpha-tocopherol and fatty acids were determined using relevant analytic methods. Importantly, in the present study, the modern analytical techniques for estimation of antioxidant capacity (measuring the chemiluminescence intensity of a luminol-hemin solution) and oxidative stability [differential scanning calorimetry (DSC), coupled with thermogravimetry (TG)] were proposed. The obtained results prove that ultrasonic irradiation enables effective extraction of grape seed oil. It was shown that the extractive yields and the amounts of total phenolic compounds and alpha-tocopherol increase with time of extraction; the optimum time was determined. Results obtained in this work show that, for both oxidative stability and antioxidant capacity, TPC have a more important role then alpha-tocopherol.

AB  - In rural areas in the territory of Pozarevac samples were taken in 10 villages that have no central water supply: Ostrovo, Petka, Kličevac, Maljurevac, Bubušinac, Bratinac, Dubravica, Batovac, Brežane, Živica. 20 samples of water have been taken from the individual wells in households in different parts of the each village. Sampling, testing methods and interpretation of results were done in accordance with the Regulation on the hygiene of drinking water includes the following parameters: smell, color, pH, consumption of KMnO4, turbidity, nitrite, nitrate, ammonia, chloride, conductivity and microbiological correctness and determination of heavy metals in the drinking water by atomic absorption spectrophotometry. The results of water analysis differ from village to village. In most communities the water is mostly hygienically improper. The research has shown that the % of microbiological safety in the tested water samples ranges from 85% (the village of Dubravica) to completely unsafe water, sampled in the village of Bare. Physical and chemical quality of drinking water ranged from 95% (the village of Dubravica), to completely unsafe water , sampled (villages Petka, Lučica and Prugovo). The most common cause of this are the elevated values of the following chemical substances: nitrate, nitrite, the turbidity of the suspended inorganic materials, the color of water as a result of the presence of colloidal dissolved substances of plant origin, the concentration of Clions, the presence of organic matter in drinking water, elevated conductivity and the pH value of the water. In the analyzed samples of drinking water in rural households ammonia concentration is within acceptable limits, while the heavy metal content in all samples of drinking water is below the maximum allowable concentration, and in some cases even below the detection limit. Uranium content in the tested water samples showed that the concentration of uranium is within the limits of natural values.
AB  - U seoskim naseljima na teritoriji grada Požarevca uzeti su uzorci vode za piće iz 10 seoskih naselja: Ostrovo, Petka, Kličevac, Maljurevac, Bubušinac, Bratinac, Dubravica, Batovac, Brežane, Živica. U svakom naselju uzeto je po 20 uzoraka vode iz individualnih bunara u domaćinstvima u različitim delovima sela. U skladu sa Pravilnikom o higijenskoj ispravnosti vode za piće radila se analiza vode za piće koja je obuhvatila: miris, boju, pH vrednost, utrošak KMnO4, mutnoću, nitrite, nitrate, amonijak, hloride, elektroprovodljivost, mikrobiološku ispravnost i sadržaj teških metala. Dobijeni rezultati analiza pokazali su da je u većini naselja voda za piće je u velikom procentu higijenski neispravna. Ispitivanja su pokazala da se % mikrobiološke ispravnosti u ispitivanim uzorcima vode kreće od 85% (selo Dubravica) do potpuno neispravne vode za piće. Fizičkohemijska ispravnost vode za piće kretala se od 95% (selo Dubravica) do potpuno neispravne vode za piće (sela Petka, Lučica i Prugovo).

abstract = "In rural areas in the territory of Pozarevac samples were taken in 10 villages that have no central water supply: Ostrovo, Petka, Kličevac, Maljurevac, Bubušinac, Bratinac, Dubravica, Batovac, Brežane, Živica. 20 samples of water have been taken from the individual wells in households in different parts of the each village. Sampling, testing methods and interpretation of results were done in accordance with the Regulation on the hygiene of drinking water includes the following parameters: smell, color, pH, consumption of KMnO4, turbidity, nitrite, nitrate, ammonia, chloride, conductivity and microbiological correctness and determination of heavy metals in the drinking water by atomic absorption spectrophotometry. The results of water analysis differ from village to village. In most communities the water is mostly hygienically improper. The research has shown that the % of microbiological safety in the tested water samples ranges from 85% (the village of Dubravica) to completely unsafe water, sampled in the village of Bare. Physical and chemical quality of drinking water ranged from 95% (the village of Dubravica), to completely unsafe water , sampled (villages Petka, Lučica and Prugovo). The most common cause of this are the elevated values of the following chemical substances: nitrate, nitrite, the turbidity of the suspended inorganic materials, the color of water as a result of the presence of colloidal dissolved substances of plant origin, the concentration of Clions, the presence of organic matter in drinking water, elevated conductivity and the pH value of the water. In the analyzed samples of drinking water in rural households ammonia concentration is within acceptable limits, while the heavy metal content in all samples of drinking water is below the maximum allowable concentration, and in some cases even below the detection limit. Uranium content in the tested water samples showed that the concentration of uranium is within the limits of natural values., U seoskim naseljima na teritoriji grada Požarevca uzeti su uzorci vode za piće iz 10 seoskih naselja: Ostrovo, Petka, Kličevac, Maljurevac, Bubušinac, Bratinac, Dubravica, Batovac, Brežane, Živica. U svakom naselju uzeto je po 20 uzoraka vode iz individualnih bunara u domaćinstvima u različitim delovima sela. U skladu sa Pravilnikom o higijenskoj ispravnosti vode za piće radila se analiza vode za piće koja je obuhvatila: miris, boju, pH vrednost, utrošak KMnO4, mutnoću, nitrite, nitrate, amonijak, hloride, elektroprovodljivost, mikrobiološku ispravnost i sadržaj teških metala. Dobijeni rezultati analiza pokazali su da je u većini naselja voda za piće je u velikom procentu higijenski neispravna. Ispitivanja su pokazala da se % mikrobiološke ispravnosti u ispitivanim uzorcima vode kreće od 85% (selo Dubravica) do potpuno neispravne vode za piće. Fizičkohemijska ispravnost vode za piće kretala se od 95% (selo Dubravica) do potpuno neispravne vode za piće (sela Petka, Lučica i Prugovo). Najčešći uzrok neispravnosti vode za piće su povišene vrednosti: nitrata, nitrita, zatim mutnoća od suspendovanih materija neorganskog porekla, boja vode kao posledica prisustva koloidno rastvorenih materija biljnog porekla, koncentracija Cl-jona, prisustvo organskih materija u vodi za piće, povišene vrednosti elektroprovodljivosti i pH vrednost vode.

AB  - In this study secondary lipid oxidation products of oil in white mustard seeds were analysed. Ground white mustard seeds were extracted by solvent extraction and the extract was analysed by gas chromatographic-mass spectrometric instrumental analysis. (Semi)volatile compounds different from fatty acids represented less than 1% of all compounds present in the extract. Except from the naturally occurring flavour and aroma compounds, a whole series of saturated and unsaturated aldehydes with 1 or 2 double bonds was identified in the extract. It was shown that most of them can be useful indicators of lipid oxidation in white mustard seeds. Additionally, it was shown that these unsaturated aldehydes, when present in high concentrations, can be indicators of an early stage of lipid oxidation in this plant.

AB  - It is well known that during biodegradation of oil under natural geological conditions, or oil pollutants in the environment, degradation of hydrocarbons occurs according to a well-defined sequence. For example, the major changes during the degradation process of n-alkanes occur in the second, slight and third, moderate level (on the biodegradation scale from 1 to 10). According to previous research, in the fourth, heavy level, when intensive changes of phenanthrene and its methyl isomers begin, n-alkanes have already been completely removed. In this paper, the ex situ natural bioremediation (non-stimulated bioremediation, without addition of biomass, nutrient substances and biosurfactant) of soil contaminated with heavy residual fuel oil (mazut) was conducted during a period of 6 months. Low abundance of n-alkanes in the fraction of total saturated hydrocarbons in the initial sample (identification was possible only after concentration by the urea adduction technique) showed that the investigated oil pollutant was at the boundary between the third and the fourth biodegradation level. During the experiment, an intense degradation of phenanthrene and its methyl-, dimethyl- and trimethyl-isomers was not accompanied by the removal of the remaining n-alkanes. The abundance of n-alkanes remained at the initial low level, even at end of the experiment when the pollutant reached one of the highest biodegradation levels. These results showed that the non-stimulated biodegradation of some hydrocarbons, despite their high biodegradability, had not proceeded completely to the end, even at final degradation stages. Under the condition of reduced availability of some hydrocarbons, microorganisms tend to opt for the less biodegradable but more accessible hydrocarbons.
AB  - Dobro je poznato da se u toku biodegradacije nafte u prirodnim geološkim uslovima, ili naftnog zagađivača u životnoj sredini, degradacija ugljovodonika odigrava prema definisanom rasporedu. Na primer, glavne promene u procesu razgradnje normalnih alkana dešavaju se u toku drugog, "blagog", i trećeg, "umerenog", stupnja (na skali biodegradacije od 1 do 10). Prema dosadašnjim istraživanjima, u četvrtom stupnju, kada počinju intenzivne promene fenantrena i njegovih metil izomera, normalni alkani su već u potpunosti uklonjeni. U ovom radu u toku perioda od 6 meseci izvođena je ex situ prirodna bioremedijacija (nestimulisana bioremedijacija bez dodatka biomase, hranljivih sastojaka i biosurfaktanata) zemljišta zagađenog mazutom. Niska obilnost normalnih alkana u frakciji ukupnih zasićenih alkana u početnom uzorku (identifikacija je bila mogućna tek nakon koncentrovanja pomoću karbamida) pokazala je da je ispitivani naftni zagađivač na granici između trećeg i četvrtog stupnja biodegradacije. Tokom eksperimenta, intenzivnu razgradnju fenantrena i njegovih metil, dimetil i trimetil izomera nije pratilo uklanjanje ostatka normalnih alkana.

AB  - Sinalbin degradation products in mild yellow mustard paste were investigated. The analyzed material consisted of a mild yellow mustard paste condiment and ground white mustard seeds which were originally used in the mustard paste production process. The samples were extracted in a Soxhlet extraction system and analyzed by gas chromatography-mass spectrometry (GC-MS) technique. The only sinalbin degradation product in ground mustard seeds was 2-(4-hydroxyphenyl)acetonitrile. The most abundant sinalbin degradation product in yellow mustard paste was 4-(hydroxymethyl)phenol. Other compounds identified in this sample were: 4-methyl phenol, 4-ethyl phenol, 4-(2-hydroxyethyl)phenol and 2-(4-hydroxyphenyl) ethanoic acid.

AB  - 'On-line' pyrolysis coupled with gas chromatography (GC) was performed for quantitative determination of poly(vinylpyrrolidone) (PVP) in wastewater sample. Gas chromatography-mass spectrometry (GC-MS) showed that the main product of pyrolysis of PVP, at high temperatures, was N-vinylpyrrolidone (NVP). After that, different amounts of commercial PVP were pyrolyzed in order to establish the correlation between the amount of generated NVP (its GC peak area) and the initial mass of pyrolyzed PVP. GC-FID analysis was used for construction of the calibration curve and for quantitative determination of PVP. Very good linear correlation was obtained between the area of NVP peak, generated during pyrolysis, and the initial mass of PVP (r2 = 0.998). Further, solutions of known concentration of PVP were prepared in destilled water ('spiked samples'). Spiked samples were preextracted with diethyl ether and n-hexane, after which the water-layer was evaporated and dissolved again in methanol. Analysis of pyrolysates of preextracted spiked samples showed that the 'recovery' of PVP was above 96 mass%. This finding suggested that pre-extraction could be applied to reduce the concentration of organic substances that could also be pyrolyzed, and thus hinder identification and quantitative determination of PVP, without significant loss of polymer. The sample of an industrial wastewater from Pančevo, Serbia was investigated in the last part of this work. The sample was preextracted in the same way as the spiked samples and than pyrolyzed. NVP was identified by GC-MS in obtained pyrolysate, which was the evidence that PVP was present in the wastewater sample. NVP was quantified on the basis of the peak area in GC-FID chromatogram, and than the concentration of PVP in wastewater sample was calculated based on calibration curve. Concentration of PVP in industrial wastewater amounted 2.5 mg/L.

abstract = "'On-line' pyrolysis coupled with gas chromatography (GC) was performed for quantitative determination of poly(vinylpyrrolidone) (PVP) in wastewater sample. Gas chromatography-mass spectrometry (GC-MS) showed that the main product of pyrolysis of PVP, at high temperatures, was N-vinylpyrrolidone (NVP). After that, different amounts of commercial PVP were pyrolyzed in order to establish the correlation between the amount of generated NVP (its GC peak area) and the initial mass of pyrolyzed PVP. GC-FID analysis was used for construction of the calibration curve and for quantitative determination of PVP. Very good linear correlation was obtained between the area of NVP peak, generated during pyrolysis, and the initial mass of PVP (r2 = 0.998). Further, solutions of known concentration of PVP were prepared in destilled water ('spiked samples'). Spiked samples were preextracted with diethyl ether and n-hexane, after which the water-layer was evaporated and dissolved again in methanol. Analysis of pyrolysates of preextracted spiked samples showed that the 'recovery' of PVP was above 96 mass%. This finding suggested that pre-extraction could be applied to reduce the concentration of organic substances that could also be pyrolyzed, and thus hinder identification and quantitative determination of PVP, without significant loss of polymer. The sample of an industrial wastewater from Pančevo, Serbia was investigated in the last part of this work. The sample was preextracted in the same way as the spiked samples and than pyrolyzed. NVP was identified by GC-MS in obtained pyrolysate, which was the evidence that PVP was present in the wastewater sample. NVP was quantified on the basis of the peak area in GC-FID chromatogram, and than the concentration of PVP in wastewater sample was calculated based on calibration curve. Concentration of PVP in industrial wastewater amounted 2.5 mg/L., U ovom radu je primenjena metoda 'on-line' pirolize u sprezi sa gasnom hromatografijom (GC) za kvantitativno određivanje poli(vinilpirolidona) (PVP) u uzorku otpadne vode.

AB  - Phenanthrene and methyl-phenanthrenes are major aromatic pollutants originating in particular from fuel oil. Phenanthrene is usually degraded faster than methyl-phenanthrenes under geological and environmental conditions. Here, we report a preferential and accelerated biodegradation of methyl-phenanthrenes versus phenanthrene in soil contaminated by fuel oil. The polluted soil was mixed with sawdust and sand to form a homogenized biopile. The biopile was continuously sprayed with microbial consortia isolated from crude oil-contaminated soil and treated by biosurfactants and nutritive substances for biostimulation. During a 6-month bioremediation experiment, a steady increase in the relative abundance of phenanthrene compared to methyl-phenathrenes was observed by gas chromatography-mass spectrometry. The increase was the highest for trimethyl-phenanthrenes, with a phenanthrene/trimethyl-phenanthrenes ratio increasing from 0.42 to 2.45. By contrast, the control, non-stimulated samples showed a ratio decrease from 0.85 to 0.11. Moreover, the results showed that the level of degradability depends on the number of methyl groups.

AB  - Bioremediation potential of bacteria and fungi isolated from sludge samples has been investigated (Danube alluvium, Panevo, Serbia). Total isolated microorganisms were divided into three parts. One part was added with actidione antifungicide. The second part was added with streptomycin antibiotic. The third part was without additives. Paraffinic type of crude oil was a substrate for assessment of bioremediation potential. The simulated oil biodegradation lasted 30, 60 and 90 days. Parallel with that, the experiments with blind trial were conducted. Extracts were isolated from the samples with chloroform in a separate funnel. They were assayed for the group composition (alkanes, aromatics, alcohols and fatty acids) by column chromatography. Alkane fraction was analysed by gas chromatography-mass spectrometry (GC-MS). The most intense oil degradation was achieved in the experiments with bacteria, somewhat weaker with consortium of fungi and bacteria, and the weakest bioremediation potential in these experiments was shown by fungi.

AB  - Poly(vinylpyrrolidone) (PVP) is a widely used and environmentally stable synthetic polymer whose occurrence in wastewater is likely. However, an appropriate method for identification and quantification of this polymer in environmental samples is still lacking. Hence, in this study an analytical method based on continuous-flow off-line pyrolysis-gas chromatography/mass spectrometry (pyrolysis-GC/MS) was developed to identify and quantify PVP in waste and surface water samples. Pyrolysis of commercial PVP, of some personal care products, of spiked water samples as well as of wastewater samples and river water samples was performed in a tube furnace at 500 degrees C under a continuous nitrogen flow. GC/MS was used for identification of specific degradation products, while GC-FID analysis was performed for quantitative determination. The concentration of PVP was calculated on the basis of the main pyrolytic product, N-vinylpyrrolidone (NVP). Very good linear correlation between initial amounts of PVP and released amounts of NVP was obtained and used as external calibration. The detected level of PVP in investigated personal care products was 6.4 (hair gel), 0.8 (laundry detergent) and 1.4%(tablets for throat disinfection). Spiked water samples, wastewater samples and river water samples were pre-extracted with hexane and diethyl ether prior to pyrolysis. It was found that the recovery of spiked samples was 94.6 +/- 1.6% which indicated that pre-extraction did not provoke significant loss of polymer. Finally, application of the developed method on real environmental samples (river water) revealed that PVP was present in effluents from wastewater treatment plants in concentrations between 0.9 mg/L and 7 mg/L, as well as in river water affected by municipal sewage emissions with concentrations around 0.1 mg/L.
