AB  - The bisphenol A (BPA) concentration was determined in 12 surface water samples of the Vrbas River and its five tributaries. The samples were taken in the area that belongs to the city of Banja Luka (Bosnia and Herzegovina). BPA was isolated using micro liquid-liquid extraction followed by derivatization and gas chromatography-mass spectrometry analysis (GC-MS). Silylation was used as a derivatization method to increase volatility and allow the GC-MS determination of BPA. The limits of detection (LOD) and quantification (LOQ), obtained by validating the procedure, were determined at 4 and 10 ng L-1, respectively. The concentrations of BPA were ranged between 33 and 354 ng L-1, and all were above the LOQ value. The lowest amount of BPA was found in the sample collected in the river Vrbas, near Švrakava estuary upstream from the city of Banja Luka. The highest concentration of BPA was recorded at the confluence of the Crkvena and Vrbas rivers, which is located in the city center. This study shows that population and human activity could affect the level of BPA in the environment.

AB  - This work aimed to examine the influence of the storage period on the content of toxic elements (As, Cd, Hg, and Pb) in five types of canned meat products regularly used in the Serbian Armed Forces. Cans of beef goulash (BG), pork ragout (PR), spam (SP), liver pate (LP), and meatballs in tomato sauce (MB), produced according to military standards and stored under regular conditions, were analyzed. Meat products were packed in tin cans made according to special requirements in terms of tin and varnish application and stored for up to 6 years. The content of toxic elements varied depending on the analyzed product. The highest average content of arsenic was in BG (10.00 μg/kg), cadmium in LP (35.91 μg/kg), and mercury and lead in PR (15.04 and 8.00 μg/kg, respectively). The average concentrations of As, Cd, Hg, and Pb in all types of canned meat products were significantly lower than the maximum permitted levels in food currently in force by local and EU legislation. The storage period did not significantly affect the level of toxic elements, although higher concentrations were found in samples stored for more than 2 years. Examination of raw materials, spices, and additives showed that the highest Cd and Pb concentrations, which can affect the total level of these elements in meat products, were found in red ground pepper (Cd above 150 μg/kg) and dish supplement (Pb of 250 μg/kg). The assessment of the weekly intake of toxic elements through canned meat showed that it is significantly lower than the values that affect adversely to human health, as determined by the FAO/WHO and EFSA. However, as there is a constant possibility of contamination of raw materials and food additives, primarily due to environmental pollution, it is recommended to monitor the content of heavy metals in food permanently and assess their risk to human health.

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  - The aim of this work was to assume the amount of BPA that can migrate to food packed into the cans coated by epoxy-phenolic lacquer. The assumption was made by determining the amount of BPA which migrates from the inner can coating to different food simulants: 3% acetic acid, 10% ethanol, their mixture (3% acetic acid +10% ethanol), and 50% ethanol. The examined tinplate cans were made by the special requirements of the Serbian Armed Forces. Further, the effect of the sterilization process and the very initial time of storage (15-105 days), on the level of BPA in the canned meatballs in tomato sauce, which are in the regular use of the Serbian Armed Forces, was examined. The BPA content was determined by the high performance liquid chromatography-mass spectrometry (HPLC-MS), and compared with BPA content found in the food simulants.

AB  - The migration of bisphenol A (BPA) from epoxy-phenolic can coating into canned meat products, produced for the needs of the Serbian Armed Forces, was investigated in this work. The tinplate cans were made according to the special military demands, filled with the beef goulash or the meatballs in tomato sauce, and preserved by sterilization. The structure of internal can coating was analyzed by FTIR spectroscopy. The migration of BPA into content of the cans was investigated after storage under regular conditions in typical military facilities. The samples of beef goulash (BG) produced in 2010-2016, and the meatballs in tomato sauce (MB) produced in 2014-2017 were tested for the presence of BPA. Thereafter, the impact of storage temperature and degree of can damage on BPA migration was examined. Both meat products were thermostated on 20 and 40 degrees C, and BPA level was measured after 3, 6, 9 and 12 months of storage. The level of BPA was determined in the content of undamaged cans, and cans with lower and higher degree of damage. The BPA was extracted from food with acetonitrile and the extracts were purified by QuEChERS procedure. The level of BPA was determined by LC-MS.

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  - Segmented poly(urethane-urea-siloxane)s (PUUS) were synthesized using 4,4'-methylenediphenyl diisocyanate (MDI) and ethylene diamine (ED) as the hard segment components and hydroxypropyl-terminated poly(dimethylsiloxane) (PDMS) as the soft segment component, where the hard segment content ranged from 38 to 65 wt%. Segmented PUUSs were prepared by a two-step polymerization procedure in tetrahydrofuran/N-methylpyrrolidone (THF/NMP) mixture with a large proportion of polar solvent. The structure, composition and hard segment length were determined by C-13 NMR and two-dimensional correlation spectroscopy. Thermal, mechanical, small-angle X-ray scattering and hydrogen bonding analyses indicated the formation of the microphase-separated copolymers with high tensile strength. Globular superstructures observed in the copolymer films by scanning electron microscopy (SEM) and atomic force microscopy (AFM) were probably arisen from the microstructural organization of the MDI-ED segments, depending on their content and length. The PUUS copolymers showed high water resistance and became more hydrophobic with increasing weight fraction of PDMS.

AB  - Segmented poly(urethane-urea-siloxanes) (PUUS) based on 4,4'- methylene diphenyl diisocyanate-ethylene diamine (MDI-ED) hard segments and hydroxypropyl-terminated poly(dimethylsiloxane) (PDMS, Mn = 1000 g mol-1) soft segments were prepared under various experimental conditions. The copolymers with constant molar ratio of hard and soft segments (PDMS:MDI:ED = 1:2:1; 20 wt. % of the hard segments) were synthesized in two different solvent mixtures, by a two-step polyaddition procedure. The first one was tetrahydrofuran/N,N-dimethylacetamide (THF/DMAc) with different co-solvent ratios (1/1, 1/2 and 1/9, v/v), whereas the second one was tetrahydrofuran/N-methylpyrrolidone (THF/NMP, 1/9, v/v). The reaction conditions were optimized by varying the co-solvents ratio, the concentration of the catalyst, the initial monomer concentration, as well as the time of the first and the second step of the reaction. The effects of the experimental conditions on the size of the PUUS were investigated by gel permeation chromatography (GPC) and dilute solution viscometry. The copolymers with the highest molecular weights were obtained in the THF/NMP mixture (1/9, v/v). The structure and composition of the copolymers were determined by 1H-NMR and FTIR spectroscopy. The morphology of the synthesized copolymers was investigated by atomic force microscopy (AFM), while the thermal properties were studied by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The surface properties were evaluated by measuring the water contact angle (WCA). The copolymers exhibited phase-separated microstructure and were stable up to 200°C in nitrogen.

Kopolimeri sa konstantnim molskim odnosom tvrdih i mekih segmenata (PDMS:MDI:ED = 1:2:1; 20 mas. % tvrdih segmenata), sintetisani su u dve različite smeše rastvarača kao reakcionog medijuma, metodom dvostepene poliadicije. Prva kombinacija rastvarača je bila smeša tetrahidrofurana (THF) i N,N-dimetilacetamida (DMAc), dok je u drugom slučaju korišćena smeša THF-a i N-metilpirolidona (NMP). Reakcioni uslovi su optimizovani u pogledu odnosa ko-rastvarača, koncentracije katalizatora, početne koncentracije monomera i vremena odigravanja prve i druge faze reakcije. Ispitan je uticaj primenjenih eksperimentalnih uslova na veličinu PUUS primenom gel-propusne hromatografije (GPC) i viskozimetrije razblaženih rastvora [η]. Kopolimeri najvećih molarnih masa su dobijeni u smeši THF/NMP (1/9, v/v). Struktura i sastav kopolimera su okarakterisani 1H-NMR i FTIR spektroskopijom. Morfologija sintetisanih kopolimera je ispitana mikroskopijom atomskih sila (AFM), dok su termička svojstva ispitana diferencijalnom skenirajućom kalorimetrijom (DSC) i termogravimetrijskom analizom (TGA). Površinska svojstva kopolimera su ispitana određivanjem kontaktnih uglova sa vodom (WCA). Kopolimeri su pokazali dvofaznu mikrostrukturu i bili su stabilni do 200°C u atmosteri azota.
