AB  - This paper presents the extraction of major and trace elements from a coal sample, in deionized water, by using three different extraction techniques. Rotary mixing and ultrasonic extraction were examined for different extraction times, while the microwave-assisted extraction was performed at different temperatures. Metal concentrations (Na, K, Ca, Mg, Al, Fe, Mn, Be, Cd, Co, Cr, Hg, As, Ni, Se, Sb and Pb) in solution were determined employing inductively coupled plasma atomic emission spectrometry; whereas the results obtained for Na, K, Ca and Mg were compared employing ion chromatography. Comparing the rotary-and ultrasonic-assisted extractions, it was shown that the former technique was more efficient for the determination of Fe, Na and Pb, whereas the latter one proved more efficient for the determination of Co and Cr ions. Microwave-assisted extraction was shown to be the most efficient method for all the tested elements in coal. In addition, sequential extraction of the elements was realized using microwave digestion. The results of the sequential extraction experiments indicated associations of investigated elements with a mineral phase and organic matrix. Sequential extraction provided information on possible leaching of As, Cd, Co, Cr, Ni, Pb, Fe and Mn under environmental conditions.

AB  - GIS is a computer-based system to input, store, manipulate, analyze and output spatially referenced data. There is a huge range application of GIS that generally sets out to fulfill: mapping, measurement, monitoring, modeling and management. In this study, GIS technology was used for the regional recognition of origin and distribution patterns of multifloral honey chemical traits in Serbia. This included organizing and analyzing the spatial and attributive data of 164 honey samples collected from different regions of Serbia during the harvesting season of 2009. Multifloral honey was characterized in regards to mineral composition, sugar content and basic physicochemical properties. The kriging method of Geostatistical Analyst was used for interpolation to predict values of a sampled variable over the whole territory of Serbia

AB  - Multifloral honey was characterized in regards mineral to composition, sugar content and basic physicochemical properties. A total of 164 honey samples were collected from different regions of Serbia during the harvesting season 2009. Univariate data analysis (descriptive statistics and analysis of variance), geographic information system and pattern recognition methods (principal component analysis and cluster analysis) were utilized in order to identify the geographical origin of honey. The content of Mg, K, and Cu, electrical conductivity and optical rotation were established as useful indicators in tracing regional differences between honey samples. Samples originating from Zlatibor region were clearly distinguished from those from the rest of Serbia, showing higher K and Mg contents, as well as higher values of optical rotation, electrical conductivity, and free acidity. The influence of the soil composition, and climate conditions, as well as the presence of particular flora on the honey composition is emphasized. The modeling of the geographic origin of honey was attempted by means of linear discriminant analysis. .

Univarijantna analiza podataka (deskriptivna statistika i analiza varijanse), zajedno sa geografskim informacionim sistemom i multivarijantnom hemometrijskom analizom (analiza glavnih komponenata i klasterska analiza) primenjene su u cilju određivanja geografskog porekla meda. Utvrđeno je da su sadržaj Mg, K i Cu, električna provodljivost i optička rotacija parametri koji ukazuju na razlike u regionalnom poreklu meda. Uzorci koji potiču iz zlatiborskog regiona su se jasno razdvojili od uzoraka iz ostalih delova Srbije na osnovu većeg sadržaja K i Mg, kao i većih vrednosti optičke rotacije, električne provodljivosti i slobodne kiselosti. Ukazano je na uticaj sastava zemljišta, klimatskih uslova i postojanja endemičnih vrsta na sastav meda. Modelovanje geografskog porekla meda je urađeno primenom linearne diskriminantne analize. .
