veštački proizvedenog 137Cs u uzorcima mahovina (28) i lišajeva (17) sakupljenim na
teritoriji Nacionalnog parka Đerdap u maju 2015. godine. U svim uzorcima mahovina i
lišajeva utvrđeno je prisustvo radionuklida. Dobijeni rezultati upućuju na zaključak da
su mahovine i lišajevi dobri biomonitori i bioindikatori radiozagađenja životne sredine,

radionuclides in moss (28) and lichen (17) samples collected on the territory of the
Djerdap national park in May 2015 are presented in this work. Radionuclide presence
was established in all moss and lichen samples. The obtained results indicate that moss
and lichen are good bioindicators of radio-pollution of the environment. It is necessary
to monitor activity levels of radionuclides in moss and lichen due to possible radiation
risks of organisms consuming them as food or using them for other purposes.

AB  - The results of the study on natural radionuclide content in 102 samples of the moss species randomly collected in 20082013 at 30 locations of eastern Serbia are presented in the paper. The activity concentration values of U-238, Ra-226, Th-232, K-40, and Be-7 determined by gamma spectrometry were within the intervals: U-238 (1.1-50) Bq kg(-1), Ra-226 (1.1-41) Bq kg(-1), Th-232 (1.4-28) Bq kg(-1), K-40 (64-484) Bq kg(-1) and Be-7 (88-227) Bq kg(-1), not standing out of the average data reported for this region. The distribution of the obtained data for Ra-226, Th-232, and U-238 activity concentration in the analysed mosses has shown values up to 10 Bq kg(-1) with frequencies 47.1 %, 54.9 % and 48.0 %, respectively. The obtained activity concentration values of primordial K-40 and cosmogenic radionuclide Be-7 were up to 500 Bq kg(-1) and about 90 % of all the results for Be-7 uptake by mosses were in the 200-250 Bq kg(-1) concentration range.

AB  - Desorption of metals K, Al, Ca, Mg, Fe, Ba, Zn, Mn, Cu and Sr from Cetraria islandica (L.) with solutions whose composition was similar to that of acid rain, was investigated. Desorption of metals from the lichen was performed by five successive desorption processes. Solution mixtures containing H2SO4, HNO3 and H2SO4-HNO3 were used for desorption. Each solution had three different pH values: 4.61, 5.15 and 5.75, so that the desorptions were performed with nine different solutions successively five times, always using the same solution volume. The investigated metals can be divided into two groups. One group was comprised of K, Ca and Mg, which were desorbed in each of the five desorption processes at all pH values used. The second group included Al, Fe, Zn, Ba, Mn and Sr; these were not desorbed in each individual desorption and not at all pH values, whereas Cu was not desorbed at all under any circumstances. Using the logarithmic dependence of the metal content as a function of the desorption number, it was found that potassium builds two types of links and is connected with weaker links in lichen. Potassium is completely desorbed, 80% in the first desorption, and then gradually in the following desorptions. Other metals are linked with one weaker link (desorption 1-38%) and with one very strong link (desorption below the metal detection limit).

AB  - Antioxidant activity (AO) of commercial propolis extracts (PEs), available on Serbian market, was determined by direct current (DC) polarography. Polarographic anodic current of 5.0 mmol L-1 alkaline solution of H2O2 was recorded at potentials of mercury dissolution. Decrease of the current was plotted against the volume of gradually added PEs. The volume of PE causing 20% current decrease was determined from the linear part of the plot. Antioxidant activity was expressed in H2O2 equivalent (HPEq), representing the volume of PE that corresponds to 1.0 mmol L-1 H2O2 decrease. Resulting HPEq ranged between 1.71 +/- 0.11 and 8.00 +/- 0.18 mu L. Range of 1,1-dipheny1-2-picryl hydrazyl (DPPH) radical scavenging activity was from 0.093 +/- 0.004% to 0.346 +/- 0.006%. Total phenolic content (TCP) of PE with superior AO activity was 5.31 +/- 0.05%g GAE, while the extract with the lowest activity contained 1.45 +/- 0.02%g GAE. Antioxidant activity, determined by polarographic method, was correlated with DPPH scavenging activity (R-2 = 0.991) and TCP (R-2 = 0.985). Validity of obtained results was further confirmed using ANOVA and post hoc Tukey HSD test. (C) 2012 Elsevier Ltd. All rights reserved.

abstract = "Antioxidant activity (AO) of commercial propolis extracts (PEs), available on Serbian market, was determined by direct current (DC) polarography. Polarographic anodic current of 5.0 mmol L-1 alkaline solution of H2O2 was recorded at potentials of mercury dissolution. Decrease of the current was plotted against the volume of gradually added PEs. The volume of PE causing 20% current decrease was determined from the linear part of the plot. Antioxidant activity was expressed in H2O2 equivalent (HPEq), representing the volume of PE that corresponds to 1.0 mmol L-1 H2O2 decrease. Resulting HPEq ranged between 1.71 +/- 0.11 and 8.00 +/- 0.18 mu L. Range of 1,1-dipheny1-2-picryl hydrazyl (DPPH) radical scavenging activity was from 0.093 +/- 0.004% to 0.346 +/- 0.006%. Total phenolic content (TCP) of PE with superior AO activity was 5.31 +/- 0.05%g GAE, while the extract with the lowest activity contained 1.45 +/- 0.02%g GAE. Antioxidant activity, determined by polarographic method, was correlated with DPPH scavenging activity (R-2 = 0.991) and TCP (R-2 = 0.985). Validity of obtained results was further confirmed using ANOVA and post hoc Tukey HSD test. (C) 2012 Elsevier Ltd. All rights reserved.",

AB  - Extraction of metals (K, Al, Ca, Mg, Fe, Cu, Ba, Zn, Mn and Sr) from dry Cetraria islandica (L.) Ach. lichen was performed using solutions similar to acid rain (solution A - H2SO4-HNO3-(NH4)(2)SO4 and solution B - H2SO4-HNO3-(NH4)(2)SO4-NH4NO3). The pH values of these solutions were 2.00, 2.58, 2.87, 3.28, and 3.75. Five consecutive extractions were performed with each solution. In all solutions, the extracted metal content, except Cu and Ca, was the highest in the first extract. The highest percentage of the metals desorbed in the first extraction was obtained using solutions with low pH values, 2.00, 2.58, and 2.87. The iowest percentage in the first extraction was obtained using solutions with pH 3.28 and pH 3.75, indicating influence of the H+ ion on the extraction. According to the results obtained, the investigated metals form two groups. The first group includes K, Al, Ca, Mg, and Fe. They were extracted in each of the five extractions at each of the pH values. The second group includes Ba, Zn, Mn, Cu, and Sr, which were not all extracted at each pH value. The first group yielded three types of extraction curves when the logarithms of extracted metal amounts were plotted as a function of the number of successive extractions. These effects indicate that three different positions (centres) of metal ion accumulation exist in the lichen (due to sorption, complex formation, or other processes present in the tissues).

The results obtained suggest that the investigated elements can be classified into ones where the highest percentage was extracted with the first extraction (K, Al, Mg, Ba, Zn and Mn) and others where the extraction percentage is relatively uniform (Ca and Fe). This indicated different bonding methods in lichen that is in accordance with literature data where two cation bonding methods in lichen were shown.

AB  - The absorption spectra of Co(II) chloride complexes, containing variable concentrations of chloride ligand, in a molten mixture of 80 mol% acetamide-20 mol% calcium nitrate tetrahydrate, were studied at 313, 333, 353, and 363 K, in the wavelength range 400-800 nm. The melt contains three possible ligands (CH3CONH2, H2O, and NO3-) for competition with added chloride ligand. Addition of chloride caused a shift of the absorption maximum of octahedral cobalt( II) nitrate towards lower energies and pronounced changes in the shape of the initial spectrum of cobalt( II) nitrate. The effect of temperature changes on the molar absorption coefficient of the Co( II) species was dependent on the chloride concentration and was attributed to the structural changes occurring in the cobalt( II) species. The STAR and STAR FA programs were applied to identify the complex ionic species and to calculate the stability constants of Co( II) complexes formed in this solvent. The results indicate the highest probability of formation of the following complex species: Co(NO3)(4)(2-), Co(NO3)(2)Cl-2(2-), and CoCl42-. Stability constants of each complex were presented for the equilibria occurring at 313, 333, 353, and 363 K. Distribution of the Co( II) species was also calculated over the ranges of chloride concentration and temperature investigated.

The simultaneous analysis of diastereo-enantiomeric HM-PAO content, as well as the content of starting DI, in different reduction mixtures were pet-formed using chiral ligand-exchange chromatography (CLEC). The separation of the samples of investigated reduction mixtures, obtained in the second step of HM-PAO synthesis, has been accomplished by using an achiral sorbent (RP- 18) and a chiral mobile phase (CMP) containing copper(II) complex with N,N-ditnethyl-L-phenylalanine (L-DM-PhA) as initial complex for CLEC. With 12 different reduction conditions, the obtained ratios of diastereoisomers d,l-HM-PAO: mesa-HM-PAO varied from 69.2:30.8 to 15.9:84.1, in comparison to the reduction in routine synthesis of HM-PAO which gives an equal mixture of diastereoisomers. The ternary mixed complexes formation recorded spectrophotometrically on addition of HM-PAO or DI to the mobile phase with binary complex Cu(L-DM-PhA)(2), due to the evidence of bathochromic shift of 46 nm for lambda(max) with significant difference in absorptivity contributes to separation mechanism.

AB  - The diastereo-enantio separation of isomeric mixtures of exametazime (HM-PAO) by liquid chromatography is described using an achiral sorbent (RP-18). A chiral eluent with the initial complex of Cu(II) and the optically active selector N,N-dimethyl-l-phenylalanine (l-DM-PhA), based on the ligand-exchange principle, has been applied. The separation is based on the presence of the immobilized binary complex Cu(l-DM-PhA)(2) and formation of mixed ternary complex. The optimal mole ratio of Cu(II):l-DM-PhA is 1:4, the pH should be between 4.1 and 4.2 and up to 0.8 mM of triethylamine is added for column presaturation with the initial complex. The elution order has been defined using isolated l-HM-PAO via l-HM-PAO L(+)tartrate and tneso-HM-PAO obtained by repeated recrystallization from the isomeric mixture of HM-PAO. Complete resolution between all isomers (R-S from 2.14 to 3.91) and partial resolution for meso(EE)/l-HM-PAO (R-S = 0.83) has been obtained. This means that the proposed chiral ligand-exchange chromatography (CLEC) can be used for determination of the isomeric purity of HM-PAO. This as an alternative method for resolution measurements with chiral columns. (C) 2003 Elsevier B.V. All rights reserved.

AB  - Depleted uranium (DU) is a by-product of uranium enrichment process and its use is very dangerous and harmful. We measured uranium concentration in the surface soil (0-5 cm depth) from bomb craters caused by cruise missiles in which DU might have been used as counterweights during NATO attack. Total uranium concentration and isotopic ratio were determined using y-spectrometry and inductively coupled plasma method. Obtained results were in the range 1.7 - 22 mg/kg dry soil that was comparable to the uranium values found in off-side locations of Serbian soils.

AB  - The hexadentate complex [Cu(H(2)1,3-pddadp)]. 1.5H(2)O (1,3-pddadp = 1,3-propanediamine-N,N-diacetate-N,N-di-3-propionate ion) has been prepared and isolated and its molecular structure determined by the single crystal X-ray diffraction technique. The complex is a trans(O-6) isomer, in which the copper(II) ion is surrounded octahedrally by two nitrogen and four oxygen atoms of 1,3-pddadp with two protonated beta-alaninate rings in trans positions. The copper atom environment is a tetragonally elongated octahedron with tetragonality (T) 0.798. A comparison of structures of the copper(II)-edta-type complexes shows an expected variation in their stereochemistry, depending on the structure of the ligand. The 1,3-pddadp ligand encircles the Cu-II ion more favourably than the edta ligand, which is capable of forming five-membered chelate rings only. Some properties of the complex are also given.
