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  - 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  - In this study, calcium alginate beads immobilizing D-limonene (solid systems) have been manufactured starting from emulsions of this flavor in sodium alginate (liquid systems). The effects of alginate concentration (0.02 and 0.03 g/mL) and flavor content (5 and 10 % w/w) on viscosity, conductivity and stability of emulsions were investigated. The flavor droplets in emulsions are bigger as polymer solution is more concentrated and contains more of the flavor. When emulsions have been subjected to electrostatic extrusion and upon Na+-Ca2+ ion exchange, smaller (similar to 960 to similar to 1450 mm) and less spherical beads were obtained (sphericity factor 0.003-0.21) compared to beads produced by simple dripping technique (without electrostatic field). When wet beads were air dried, they shrunk less if they had higher content of the flavor. Novel mathematical model describing swelling kinetics of dried beads is developed. In this work, D-limonene was efficiently immobilized within Ca-alginate beads (immobilization efficiency similar to 50 to similar to 77%) and its thermal stability was confirmed by TG/MS analysis.

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  - Ispitivani su degradacioni proizvodi sinalbina u blagom senfu. Ispitivani materijal se sastojao od blagog senfa i od mlevenog semena bele slačice koja je korišćena u procesu proizvodnje senfa. Uzorci su ekstrahovani u Soxhlet-ovom ekstraktoru i analizirani gasno hromatografsko-masenospektrometrijskom (GC-MS) tehnikom. Jedini degradacioni proizvod sinalbina identifikovan u mlevenom semenu slačice je 2-(4-hidroksifenil)acetonitril. Najobilniji degradacioni proizvod sinalbina u blagom senfu je 4-(hidroksimetil)fenol. Druga jedinjenja identifikovana u ovom uzorku su: 4-metilfenol, 4-etilfenol, 4-(2-hidroksietil)fenol i 2-(4-hidroksifenil) etanska kiselina. Ova jedinjenja bila su prisutna u uzorku senfa u znatno manjoj količini nego 4-(hidroksimetil)fenol. Iako se za neka od njih može reći da su strukturno srodna sa glukozinolatom sinalbinom, ovaj odnos tek treba dokazati. 4-(Izotiocianatometil) fenol, ljuti degradacioni proizvod sinalbina, nije identifikovan u ispitivanom mlevenom semenu slačice niti u ispitivanom uzorku senfa. Ovi rezultati su pokazali da je 4-(izotiocianatometil)fenol nestabilan intermedijer degradacije sinalbina pod uslovima industrijskog procesa pripreme semena bele slačice i dodatno, da ovo jedinjenje ne doprinosi ljutom ukusu ispitivanog senfa.

Other compounds identified in this sample were: 4-methyl phenol, 4-ethyl phenol, 4-(2-hydroxyethyl)phenol and 2-(4-hydroxyphenyl) ethanoic acid., Ispitivani su degradacioni proizvodi sinalbina u blagom senfu. Ispitivani materijal se sastojao od blagog senfa i od mlevenog semena bele slačice koja je korišćena u procesu proizvodnje senfa. Uzorci su ekstrahovani u Soxhlet-ovom ekstraktoru i analizirani gasno hromatografsko-masenospektrometrijskom (GC-MS) tehnikom. Jedini degradacioni proizvod sinalbina identifikovan u mlevenom semenu slačice je 2-(4-hidroksifenil)acetonitril. Najobilniji degradacioni proizvod sinalbina u blagom senfu je 4-(hidroksimetil)fenol. Druga jedinjenja identifikovana u ovom uzorku su: 4-metilfenol, 4-etilfenol, 4-(2-hidroksietil)fenol i 2-(4-hidroksifenil) etanska kiselina. Ova jedinjenja bila su prisutna u uzorku senfa u znatno manjoj količini nego 4-(hidroksimetil)fenol. Iako se za neka od njih može reći da su strukturno srodna sa glukozinolatom sinalbinom, ovaj odnos tek treba dokazati. 4-(Izotiocianatometil) fenol, ljuti degradacioni proizvod sinalbina, nije identifikovan u ispitivanom mlevenom semenu slačice niti u ispitivanom uzorku senfa. Ovi rezultati su pokazali da je 4-(izotiocianatometil)fenol nestabilan intermedijer degradacije sinalbina pod uslovima industrijskog procesa pripreme semena bele slačice i dodatno, da ovo jedinjenje ne doprinosi ljutom ukusu ispitivanog senfa.",

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  - The bioremediation potential of the aerobic zymogenous microorganisms in soil (Danube alluvium, Pancevo, Serbia) for crude oil biodegradation was investigated. A mixture of paraffinic types of oils was used as the substrate. The laboratory experiment of the simulated oil biodegradation lasted 15, 30, 45, 60 and 75 days. In parallel, an experiment with a control sample was conducted. Extracts were isolated from the samples with chloroform in a separation funnel. From these extracts, the hydrocarbons were isolated by column chromatography and analyzed by gas chromatography mass spectrometry (GC MS). n-Alkanes, isoprenoids, phenanthrene and its derivatives with one and two methyl groups were quantitatively analyzed. The ability and efficiency of zymogenous microorganisms in soil for crude oil bioremediation was assessed by comparison between the composition of samples which were exposed to the microorganisms and the control sample. The investigated microorganisms showed the highest bioremediation potential in the biodegradation of n-alkanes and isoprenoids. A considerably high bioremediation potential was confirmed in the biodegradation of phenanthrene and methyl phenanthrenes. Low bioremediation potential of these microorganisms was proven in the case of polycyclic alkanes of the sterane and triterpane types and dimethyl phenanthrenes.

AB  - Contamination of groundwater by methyl tertiary butyl ether (MTBE), that is detected in wastewater of petrochemical industry, is an increasing problem to water supply companies. The subjects of this research were the methods of photolytic, photocatalytic and microbiological degradation of methyl tertiary butyl ether (MTBE) dissolved in wastewaters. The effects of concentrated solar radiation simulated with sodium lamp (SONT UV 400) have been investigated in laboratory experiments. Our result indicated that bacteria Pseudomonas strain CY, isolated from the kerosene, and added alone, was able to gradually degrade MTBE and to decrease its concentration for 93.6% in 12 h. However, the percentage of photolytic degradation decrease in only 4 h was 99.2%. By adding Pseudomonas strain CY after 4 h of light treatment, the degradation was enhanced to 99.55% in additional 5 h. The photocatalytic process was performed in slurry-catalyst reactor with different concentrations of TiO2 catalyst: 5, 0.5 and 0.25 g/L. The MTBE degradation producing carbon dioxide reached 91% in only 150 min, when 5 g/L of catalyst was used.

AB  - BACKGROUND: , Aims and Scope. In oil spill investigations, one of the most important steps is a proper choice of approaches that imply an investigation of samples taken from different sedimentary environments, samples of oil contaminants taken in different periods of time and samples taken at different distances from the oil spill. In all these cases, conclusion on the influence of the environment, microorganisms or migration on the oil contaminants' composition can be drawn from the comparison of chemical compositions of the investigated contaminants. However, in case of water contaminants, it is very important to define which part of organic matter has been analyzed. Namely, previous investigations showed that there were some differences in chemical composition of the same oil contaminant depending on the intensity of its contact with ground water. The aim of this work is to define more precisely the interactions between oil contaminant and water, i.e. the influence of the intensity of interaction between the oil contaminant and water on its chemical composition. The study was based on a comparison of four fractionated extracts of an oil pollutant, after they had been analyzed in details. Methods. Oil polluted surface water (wastewater canal, Pancevo, Serbia) was investigated. The study was based on a comparison of four extracts of an oil contaminant: extract I (decanted part), and extracts 2, 3 and 4 (extracted by shaking for 1 minute, 5 minutes and 24 hours, respectively). The fractionated extracts were saponified with a solution of KOH in methanol, and neutralized with 10% hydrochloric acid. The products were dissolved in a mixture of dichloromethane and hexane, and individually fractionated by column chromatography on alumina and silica gel (saturated hydrocarbon, aromatic, alcohol and fatty acid fractions). n-Alkanes and isoprenoid aliphatic alkanes, polycyclic alkanes of sterane and triterpane types, alcohols and fatty acids were analyzed using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). delta C-13(PDB) values of individual n-alkanes in the aliphatic fractions were determined using gas chromatography-isotope ratio monitoring-mass spectrometry (GC-irmMS). Results and discussion. Extracts 1 and 2 are characterized by uniform distribution of n-alkanes, whereas extract 3 is characterized by an even-numbered members dominating the odd-ones, and extract 4 showed a bimodal distribution. Extract I is characterized by the least negative delta C-13(PDB) values of C-19-C-26 n-alkanes. Sterane and triterpane analysis confirmed that all extracts originated from the same oil contaminant. n-Fatty acids, C-19-C-24, in all extracts are very low, being somewhat higher in extract 4. Even-numbered n-alcohols, C-12-C-16, were identified in the highest concentration in extract 3. It was assumed that algae were responsible for the composition of extract 3. Furthermore, a possible reason for higher concentrations of C-19-C-26 n-alkanes and C-19-C-24 fatty acids in extract 4 is the formation of inclusion compounds with colloidal micelles formed between the oil contaminant's NSO-compounds and water. Conclusion. It was undoubtedly confirmed that there were specific differences in the compositions of the different extracts depending on the intensity of the interaction between the oil contaminant and the surface water. Recommendation and Outlook. When comparing the composition of oil contaminants from different water samples (regardless of the ultimate investigation goal) it is necessary to compare the extracts isolated under the same conditions, in other words, extracts that were in the same or very similar interaction with water.

When comparing the composition of oil contaminants from different water samples (regardless of the ultimate investigation goal) it is necessary to compare the extracts isolated under the same conditions, in other words, extracts that were in the same or very similar interaction with water.
