AB  - Size-segregated aerosol samples were collected using six stages High Volume Cascade Impactor. Aerosol mass and water soluble ions concentrations were determined. The Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model was used to study the origin of air masses arriving to Belgrade in the investigated period. The obtained results of aerosol mass and water-soluble ion concentrations have been divided into six sub-data sets based on air mass categories. The highest average mass concentration of the fine mode (D-p  lt = 0.49 mu m) was found for air masses coming to Belgrade from the southeast and northwest directions, and of the coarse mode (3.0  lt  D-p  lt = 7.2 mu m) for air masses arriving from the northwest direction. The highest concentrations of SO42- were found in the fine particles transported to the investigated area by air masses from southeast direction. The analysis of contribution of marine aerosol components (Na+ and Cl-), the Correlation and Cluster Analysis indicated the influence of marine aerosol on urban aerosol of the central Balkans coming from the Western Mediterranean and northern direction. NH4+ and SO42- and K+ dominated in the fine mode for all air mass categories. PCA demonstrated the dominant impact of secondary aerosol formation processes on urban aerosols.

AB  - In this study, a fast and simple method is proposed for determination of arsenic in wine employing inductively coupled plasma atomic emission spectroscopy and internal standard technique. First Co, Bi, V and Y were evaluated as internal standards to minimize transport interferences. All samples and reference solutions were automatically spiked by autosampler, eliminating the need for manual dilutions. The result demonstrated that vanadium can be used as an internal standard. The experimental parameters (plasma power and nebulization flow rate) were optimized. The relative standard deviations (R.S.D) of measurements varied from 11 to 6.0% and 3.2 to 8.7% (n=12) with and without internal standardization, respectively. Recoveries in the 95-103% range for As spiked samples were obtained. (C) 2010 Elsevier B.V. All rights reserved.

AB  - Arsenic reduction in drinking water can include treatment by adsorption, switching to alternative water sources, or blending with water that has a lower arsenic concentration. Commercial sorbents MTM, Greensand and BIRM (Clack Corporation) were modified with zirconium and titanium after activation. The modifications were performed with titanium tetrachloride and zirconium tetrachloride. The modified sorbents were dried at different temperatures. The sorption of arsenate and arsenite dissolved in drinking water (200 mu g L(-1)) onto the sorbents were tested using a batch procedure. After removal of the sorbent, the concentration of arsenic was determined by hydride generation atomic absorption spectrometry (HG-AAS). Zirconium-modified BIRM showed the best performance for the removal of both arsenite and arsenate. Modification of the greensand did not affect arsenic sorption ability. Zirconium-modified BIRM diminished the concentration of total As to below 5 mu g L(-1).
AB  - Uklanjanje arsena iz podzemnih voda može uključivati tretman sorpcijom, prelazak na alternativne izvore vode ili mešanje sa vodom koja sadrži niske koncentracije arsena. Komercijalni sorbenti MTM, Greensand i BIRM su modifikovani cirkonijumom i titanom posle aktivacije. Modifikacija je urađena titan-tetrahloridom i cirkonijum-tetrahloridom. Modifikovani sorbenti su sušeni na različitim temperaturama. Sorpcija arsenata i arsenita rastvorenih u pijaćoj vodi je testirana batch postupkom. Posle uklanjanja sorbenta koncentracija arsena je određena HG-AAS metodom. BIRM modifikovan cirkonijumom je pokazao najbolje rezultate u uklanjanju arsenita i arsenata. Modifikacija Greensend-a nije uticala na povećanje sorpcione moći. BIRM modifikovan cirkonijumom je smanjio koncentraciju arsena ispod 5 μg L-1.

AB  - Fresh raspberry (Rubus idaeus), cultivar Willamette, was freeze-dried (lyophilization). A byproduct of lyophilization is "fine dust" of raspberry consisting of finely ground raspberry fruit body and seed. The seeds were separated. The seed oil was isolated and its physical and chemical characteristics were determined. Parameters that characterize the seed and quality of the oil were examined, including fatty acid composition, oxidative stability under different storage conditions, and radical-scavenging activity. The fatty acid composition was determined by GC/FID and the contents of the dominant fatty acids were found as: oleic 16.92%, linoleic 54.95%, and alpha-linolenic acid 23.97%. The oxidative stability of the oil was poor. The induction period by Rancimat test at 100 degrees C was 5.2 h. The radical-scavenging activity is similar to that of resveratrol [1,3-benzenediol 5-(1(E)-2-4-hydroxy-phenyl-ethyl)]. Although this product is used in the candy industry, it would be far more useful if raspberry oil of satisfactory quality could be extracted. This paper demonstrates that sifted lyophilized seeds can be used for the extraction of oils. This process allows for maximal usage of the byproducts, reduces losses and it increases the development of new products.
