AB  - Type of the wood used for the aging highly influences the quality of alcoholic beverages. In this research we explored the potential of cyclic voltammetry (CV) and differential pulse voltammetry (DPV) to establish fingerprints characteristic for each wood and to enable determining the type of the wood used in the aging process. Eleven different wood samples were used to prepare three different types of spirits during 15 months. The highest extraction rate was obtained during the first month, while further aging was followed with almost constant amount of extracted polyphenols. Black locust, myrobalan plum, and mulberry extracts were discriminated from the spirits aged in oak and wild cherry wood when statistical analysis was applied. Although clear classification of all samples was not achieved, this long term study demonstrated a potential of both CV and DPV for differentiating wood species used in the aging, hence in the quality control of spirits. © 2020 Elsevier Ltd

AB  - Urban airborne particles contain a wide spectrum of components, known to have harmful effects on human health. This study reports a detailed investigation of fine particulate matter (PM2.5), chemical content and oxidative potential derived from two different urban environments. During summer and winter, 20-day campaigns were conducted at Belgrade city center (urban-background site – UB) and Bor (urban-industrial site – UI). Using various analytical techniques, carbonaceous compounds, water-soluble inorganic ions, major and trace elements were determined, while the oxidative potential of PM2.5 was estimated by dichloro-dihydro-fluorescein diacetate (DCFH-DA) assay (OPDCFH values). The mean PM2.5 concentrations in both urban environments were above the recommended daily value, and the dominant PM2.5 mass contributor was organic matter (29–55%). The OC/EC ratio was significantly higher at UB site during winter, which was an indication of a considerable contribution of secondary organic carbon to the overall organic carbon (OC). Water-soluble organic carbon (WSOC) was also higher at UB than at UI site, and it probably came from the same sources as OC. In general, the different partition of secondary organic aerosol (SOA) in warm and cold periods affected the number of organic components. Sulfates and nitrates were the most abundant ions at both sites and they counted approximately 40% (summer) and 50% (winter) of total ions. Further, the concentrations of the most elements, particularly some potentially carcinogenic elements such as As, Cd and Pb were significantly higher at UI, due to the emissions from the copper smelter complex in the vicinity. The mean OPDCFH values were similar during the summer at both sampling sites, whereas a statistically significant difference between sites was noticed in favor of UB environment in winter.

AB  - Chlorine dioxide (ClO2) degradation of the organophosphorus pesticides azamethiphos (AZA) and dimethoate (DM) (10 mg/L) in deionized water and in Sava River water was investigated for the first time. Pesticide degradation was studied in terms of ClO2 level (5 and 10 mg/L), degradation duration (0.5, 1, 2, 3, 6, and 24 h), pH (3.00, 7.00, and 9.00), and under light/dark conditions in deionized water. Degradation was monitored using high-performance liquid chromatography. Gas chromatography coupled with triple quadrupole mass detector was used to identify degradation products of pesticides. Total organic carbon was measured to determine the extent of mineralization after pesticide degradation. Real river water was used under recommended conditions to study the influence of organic matter on pesticide degradation. High degradation efficiency (88–100% for AZA and 85–98% for DM) was achieved in deionized water under various conditions, proving the flexibility of ClO2 degradation for the examined organophosphorus pesticides. In Sava River water, however, extended treatment duration achieved lower degradation efficiency, so ClO2 oxidized both the pesticides and dissolved organic matter in parallel. After degradation, AZA produced four identified products (6-chlorooxazolo[4,5-b]pyridin-2(3H)-one; O,O,S-trimethyl phosphorothioate; 6-chloro-3-(hydroxymethyl)oxazolo[4,5-b]pyridin-2(3H)-one; O,O-dimethyl S-hydrogen phosphorothioate) and DM produced three (O,O-dimethyl S-(2-(methylamino)-2-oxoethyl) phosphorothioate; e.g., omethoate; S-(2-(methylamino)-2-oxoethyl) O,O-dihydrogen phosphorothioate; O,O,S-trimethyl phosphorodithioate). Simple pesticide degradation mechanisms were deduced. Daphnia magna toxicity tests showed degradation products were less toxic than parent compounds. These results contribute to our understanding of the multiple influences that organophosphorus pesticides and their degradation products have on environmental ecosystems and to improving pesticide removal processes from water.

AB  - The aim of this study was to investigate, analyze, and compare applied techniques suitable for achieving efficient removal of organophosphorus pesticides (OPPs) (malathion and fenitrothion) from aqueous solutions and analyze the degradation products and processes. Pesticide degradation efficiency (%) was monitored by high-performance liquid chromatography (HPLC) equipped with a photodiode array detector (DAD), while mineralization degree was determined by total organic carbon analysis (TOC). Daphnia magna was used for screening the environmental safety aspects of the degradation methods, i.e., for assessing the toxicity of solutions obtained after degradation. Additionally, a surface river water was utilized to examine the likely influence of organic matter on the pesticides’ degradation. Pesticide degradation products were identified using gas chromatography with a triple quadrupole mass detector (GC-MS/MS) as well as ultrahigh-performance liquid chromatography coupled with a linear ion trap, Orbitrap mass spectrometer (UHPLC-LTQ Orbitrap MS), and a simple pesticide degradation mechanism is proposed. Removal of pesticides from water using chlorine dioxide was successful, resulting in high degradation efficiency (98% for malathion and 81% for fenitrothion). Partial mineralization was achieved, and Daphnia magna mortality decreased in the waters containing degradation products (compared with the parent pesticides), indicating that the solutions formed were less toxic than the parent pesticides. Lower degradation rates (80% for malathion and 72% for fenitrothion) in Sava River water were measured, indicating the influence of the organic matter contained in this naturally occurring surface water. The results prove that chlorine dioxide could be used as an agent for successful removal of these OPPs from water.

AB  - Electrochemical degradation procedure for the removal of organic dye Reactive Blue 52 using nano-magnetite-doped carbonaceous electrodes was proposed. The electrode was prepared by calcination of graphite grains mixed with phenol–formaldehyde binder modified with iron nitrate. The morphology and phase composition of the electrodes were investigated using scanning electron microscopy and powder X-ray diffraction. Electrochemical degradation was done in Nafion membrane-divided cell where anodic part was filled with color solution and cathodic with supporting electrolyte. Parameters affecting on decolorization rate were investigated. A high increase in the removal efficiency, under optimized parameters, was noticed using carbon electrodes containing 1 mass% of magnetite in the presence of 3 mM hydrogen peroxide and 7 mass% of magnetite in the presence of 10 mM hydrogen peroxide. Almost 100% decolorization was achieved during 30 min with 62–77% of the mineralization. Based on these results, it can be concluded that this approach offered green, cheap and efficient degradation of reactive dyes and could be used as promising candidate for wastewater processing in the textile industry.

AB  - Background of the study – Among fruits, berry fruits contain a very large complex of chemical compounds that are responsible for their antioxidant properties. As far as we know there is no data available from cyclic voltammetry studies of berry fruits. Objectives – The first objective of the present work was to investigate the electrochemical properties of antioxidants present in four types of berry fruits: strawberries, blackberries, blueberries and red raspberries. The second objective was to establish the correlation between antioxidant capacities obtained from cyclic voltammograms with those obtained using spectrophotometric techniques. Methods – Evaluation of antioxidant activity of 15 berry samples (strawberry, blackberry, blueberry and raspberry) has been carried out using cyclic voltammetry (CV). CVs were taken in the potential range between 0 mV and 800 mV with a scan rate of 100 mV s-1. Results – A pronounced anodic current peak observed between 0.524 V and 0.540 V in all analyzed berry samples can be ascribed to anthocyanins, which are the major contributors to the antioxidant capacity of investigated berries. Results obtained from CVs were compared with those obtained by using DPPH, ABTS, FRAP and RP assays. ACI parameters were determined for each berry sample by assigning all the assays an equal weight. According to obtained results, the highest ACI had blueberry samples, followed by blackberry, raspberry and strawberry samples. Also, high positive correlations were found between antioxidant capacities deduced from CVs with those obtained using FRAP (R2 = 0.8630, p = 0.0006), RP (R2 = 0.7426, p = 0.0004), DPPH (R2 = 0.7680, p = 0.0001) and ABTS (R2 = 0.8710, p = 0.000002). In addition, high positive correlations were also found between total phenols, flavonoids, anthocyanins and CV antioxidant capacity (R2 = 0.8091, p = 0.0005; R2 = 0.8341, p = 0.0002; R2 = 0.7163, p = 0.0007), respectively. Conclusion – Obtained results showed that the cyclic voltammetry is a suitable method for the determination of the reducing capacity based on the electrochemical properties of compounds under the test. © ISHS 2019.

AB  - The degradation of two sulfonylurea herbicides, nicosulfuron and thifensulfuron methyl in water by chlorine dioxide, was studied for the first time in this paper. In order to examine the optimal parameters for degradation of both herbicides, degradation was investigated under light or dark conditions with different amount of chlorine dioxide, different degradation periods, and at different pH values. Degradation efficiency of herbicides was monitored using high-performance liquid chromatography with photodiode array detection (HPLC-DAD). The degradation products were analyzed by gas chromatography with triple quadrupole mass detector (GC–QQQ). Three products were identified after degradation of nicosulfuron and two products after degradation of thifensulfuron methyl. Total organic analysis (TOC) gave insight into some differences in degradation mechanisms and degrees of mineralization after degradation of the herbicides using chlorine dioxide. A simple mechanism of herbicide degradation was proposed. Acute toxicity tests were performed on the products produced after degradation with chlorine dioxide, and the results showed that the degradation products were less toxic than the parent compounds. The findings of the present study are very useful for the treatment of wastewaters contaminated with herbicides. © 2018, Springer Nature Switzerland AG.

AB  - This work present a new approach for the detection of relatively new herbicide pethoxamid (POA), a first electrochemical behavior and determination based on its oxidation on boron-doped diamond electrode in Britton-Robinson buffer solution at pH 4. Square wave voltammetric technique was used for quantification of POA at anodic potential of 1.35 V vs reference Ag/AgCl electrode. The proposed electroanalytical method is operational in the linear working range from 3 to 100 μM of POA with a limit of detection of 1.37 μM. The developed analytical procedure was successfully tested for determination of this herbicide in standard/spiked river water samples and commercial herbicide Successor T SE/spiked river water samples, offering a simple, fast and inexpensive alternative way of pesticide determining to chromatographic methods employed for this purpose.

AB  - The electrochemical behavior of four dialkyl esters (methyl, ethyl, n-propyl and n-butyl) of (S,S)-α,α ′-(1,2-ethanediyldiimino)- bis[cyclohexanepropanoic acid] with moderate antitumor activity has been studied by cyclic voltammetry. I-E curves recorded at boron-doped diamond electrode in -2.00 < Ep < 0.00 V range show a single oxidative peak located in the -0.95 < Ep,a < -0.52 V region in a form of one-electron wave. The electrochemical processes appear to be irreversible for all compounds except for the compound with methyl substituent which demonstrates well-defined reversible electron transfer. Derivatives with bulkier moieties are easier to oxidize. For all investigated compounds an amine-centered redox process is dominant. Further investigation indicates that electrochemical reaction is diffusion controlled, chemically irreversible process. The results are discussed in terms of linking their electrochemical activity to antitumor effect. © 2018 The Electrochemical Society.

AB  - Redox properties of a set of aryldiketo acids (ADKs), small organic molecules that comprise 2,4-dioxobutanoic acid moiety, were studied. Along with well-known HIV-1 integrase (IN) inhibition, ADKs exert widespread biological activities. The aim of this work was to evaluate the effects of aryl substitutions on the properties of the dioxobutanoic moiety that is involved in key interactions with metal ions within the active sites of target enzymes. The effect of pH on the electronic properties of nine congeners was examined using cyclic voltammetry and differential pulse polarography. The compounds were chosen as a simple set of congeners bearing Me-groups on the phenyl ring, which should not be involved in electrochemical reactions, leaving the diketo moiety as the sole electrophore. The substitution pattern was systematically varied, yielding a set having different torsion between the phenyl ring and the aryl keto group (Ar-C(O)). The protonation state of the ADKs at different pH values was determined from the experimentally obtained pK(a) values. The results showed that an equal number of protons and electrons were involved in the oxidation and reduction reactions at the surface of the electrode. Quantitative linear correlations were found between the reduction potentials and the energies of the frontier orbitals, calculated for neutral, mono-anionic and the corresponding radical anionic species, and the steric parameter as two independent variables.

abstract = "Redox properties of a set of aryldiketo acids (ADKs), small organic molecules that comprise 2,4-dioxobutanoic acid moiety, were studied. Along with well-known HIV-1 integrase (IN) inhibition, ADKs exert widespread biological activities. The aim of this work was to evaluate the effects of aryl substitutions on the properties of the dioxobutanoic moiety that is involved in key interactions with metal ions within the active sites of target enzymes. The effect of pH on the electronic properties of nine congeners was examined using cyclic voltammetry and differential pulse polarography.

AB  - Propolis, as a beneficial natural product, has found application in the food and pharmaceutical industries as a food preservative, active packaging material as well as a main component of propolis containing products. Quality control of propolis has thus gained in importance. We used simple, fast, and low-cost techniques such as UV/Vis spectrophotometry and cyclic voltammetry applied in combination with principal component analysis to confirm the presence of two botanical sub-types of propolis. Cyclic voltammetry, as a green, sensitive, and convenient technique suitable for investigation of chemical profile, together with multivariate chemometrics technique, was used for the first time for characterization and classification of propolis. UV/Vis spectroscopy was applied in two aspects, absorption at certain wavelength for the quantitative determination of analytes, i.e. determination of quality control parameters, and spectral profiles, for the confirmation of the existence of two botanically different poplar types. All investigated Serbian propolis samples were characterized with specific chemical patterns and were classified in two main botanical varieties, so-called orange and blue. The results confirmed that the applied methods have a potential to be used for the discrimination of complex natural products such as propolis.

AB  - Mass concentrations of particulate matter (PM) fractions were measured in educational buildings in the city of Nis, Serbia. Two sampling campaigns were conducted in winter periods. The first campaign was in the period from 21 February to 15 April 2010 at the Faculty of Occupational Safety (FOS) and the second campaign was from 20 March to 4 April 2013 at the primary school Void Karadorde (VK). PM measurements were carried out with low volume samplers Sven/Leckel LVS3. The average daily PM10 concentration inside the FOS (47.0 +/- 21.8 mu g/m(3)) was lower than PM10 concentration in outdoor air (50.7 +/- 28.1 mu g/m(3)). The average daily PM10 concentration inside the VK (54.6 +/- 17.6 mu g/m(3)) was higher than in outdoor air (47.9 +/- 22.8 mu g/m(3)). The 24-hours, average PM10 concentrations at FOS exceeded the EU limit value (50 mu g/m(3)) during 34% of days outdoors and 39% of days indoors. The 24-hours average PM10 concentrations at VK exceeded the limit value during 35% of days outdoors and 53% of days indoors. The 24-hours average PM2.5 concentrations at VK exceeded the WHO daily mean guideline value (25 mu g/m(3)) during 71% of days outdoors and 88% of days indoors. The average PM10 I/O ratio at VK was 1.57 during teaching hours, and 1.00 during no teaching hours. Similarly, average PM2.5 I/O ratio at VK was 1.11 during teaching hours and 0.90 during no teaching hours. Average daily PM2.5/PM10 ratio in the ambient air at VK was 0.87 and 0.82 at FOS. Very strong correlations between the indoor and outdoor PM concentrations were observed at VK during no teaching hours (r GT 0.8). Moderate to strong negative correlations were found between the wind speed and PM at both schools. High outdoor PM concentrations and resuspension of particles are possible reasons for the elevated indoor PM concentrations found in the study.

AB  - Colour changes in Gradia Direct (TM) composite after immersion in tea, coffee, red wine, Coca-Cola, Colgate mouthwash, and distilled water were evaluated using principal component analysis (PCA) and the CIELAB colour coordinates. The reflection spectra of the composites were used as input data for the PCA. The output data (scores and loadings) provided information about the magnitude and origin of the surface reflection changes after exposure to the staining solutions. The reflection spectra of the stained samples generally exhibited lower reflection in the blue spectral range, which was manifested in the lower content of the blue shade for the samples. Both analyses demonstrated the high staining abilities of tea, coffee, and red wine, which produced total colour changes of 4.31, 6.61, and 6.22, respectively, according to the CIELAB analysis. PCA revealed subtle changes in the reflection spectra of composites immersed in Coca-Cola, demonstrating Coca-Colas ability to stain the composite to a small degree.

AB  - Mentha piperita L. (Lamiaceae) was cultivated under the controlled laboratory conditions in the presence of varying levels of trivalent and hexavalent chromium in order to determine its capacity to control chromium uptake and its tolerance limit. The plants were grown in pots at 25 degrees C with controlled soil moisture (about 80 % of the water retention capacity). The soil was treated with increasing concentrations of Cr(NO3)3 (40, 80, 120, and 200 mg kg(-1)) and K2Cr2O7 (2.5, 5, 10, and 15 mg kg(-1)). A control group of plants was grown without the addition of chromium to the soil. For each concentration, three acidity levels were tested: natural, one pH unit below and one above the natural acidity of the soil (pH(2) 6, pH(1) 5 and pH(3) 7). The plant samples were digested according to the standard procedure and chromium content was determined by GFAAS. For all plants, the transportation index was calculated and the results (expressed in mg kg(-1)) at pH(1), pH(2) and pH(3), respectively, were: 0.21-0.80, 0.06-1.06 and 0.04-0.52. The recoveries were good (72.73-115.3 %) as evidenced by the analysis of certified reference materials (NIST SRM 8433 - Corn Bran and NIST SRM 1547 - Peach Leaves). The mobility of chromium through the plants tissues is discussed in regard to its competition with iron and manganese for transport binding sites; hence Mn and Fe were also determined.

AB  - A simulation experiment was used to study the interaction of river water with different soils (amble land, orchards, meadows, pastures and forestland). The results obtained by sequential extraction before and after the simulation experiment were compared in order to determine the substrates of the heavy metals in inundated land and to evaluate their mobility. Samples of various soils were collected from the region of the future accumulation Lake Bogovina (Serbia) and analysed for ten elements using AAS, GFAAS and ICP. Investigation of the nature of the association of heavy metals and the identification of their substrates were provided by a five-step sequential extraction. Correlation analysis was used as a method for the determination of the substrates for heavy metals. The good correlation among the microelements and certain macroelements indicated the substrates of the microelements. Manganese and iron had a good correlation with most of the microelements. Calcium had only a few correlations with some microelements. Some elements, such as nickel and cadmium, had one substrate before and another after the simulation experiment.

AB  - In this paper we report results of structural, spectroscopic, and magnetic investigations of MgFe2O4 nanoparticles prepared by soft mechanochemical synthesis. MgFe2O4 nanoparticles crystallize in Fd3m space group with mixed cation distribution and reduced percentage of Fe3+ at tetrahedral (8a) sites. Discrepancy in the cation distribution compared to that in the bulk Mg-ferrite is one of the highest known. X-ray line broadening analysis reveals crystallite size and strain anisotropy. The saturation magnetization, M-sat=62 emu/g measured at 5 K is twice higher than that found in the bulk counterparts. Such high value of M-sat is attributed to the low value of cation inversion parameter (delta=0.69), to the core/shell structure of the nanoparticles and to the surface/volume ratio. Moumlssbauer spectrum collected at room temperature reveals ferrimagnetic ordering between Fe3+ ions in 8a and 16d sites, while zero-field-cooled (ZFC) and field-cooled (FC) M(T) measurements were shown superparamagnetic state above 350 K.

AB  - Samples of various ecochemical types of soil were collected in the region of the future accumulation of Lake Bogovina (Serbia). They were analyzed for ten elements using AAS, GFAAS and ICP. Investigation of the nature of association of heavy metals and identification of their substrates was provided by sequential extraction in five steps by successive extraction of soil samples with different mediums. Besides the acid soluble residual phase, most microelements were extracted in the easily and moderate reducible phases. Correlation between manganese and iron from the second and third phase with trace metals from non-residual phases was provided in order to determine their bioavailability. Besides principal component and cluster analysis, the enrichment factors were provided in order to check the impact of anthropogenic factors on trace elements. Most samples contained trace elements mainly from crustal origin with the exception of cadmium.
