AB  - To contribute to the development of urban beekeeping, we designed this study to obtain more information about the contamination of urban bee products with toxic metals, polycyclic aromatic hydrocarbons (PAHs), and pesticides. The samples of honey (N=23), pollen (N=13), and floral nectar (N=6) were collected from the experimental stationary apiary of the Belgrade University Faculty of Agriculture located in centre of Zemun (a municipality of the Belgrade metropolitan area) in 2015 and 2016. Metals (Pb, Cd, As, Cu, Zn, Fe, Mn, Ni, Cr, and Hg) were determined with inductively coupled plasma quadrupole mass spectrometry (ICP-QMS). Polycyclic aromatic hydrocarbons (PAHs) were analysed with high-performance liquid chromatography with fluorescence detection (HPLC-FLD). Pesticides were analysed with gas chromatography - mass spectrometry (GC-MS). The honey samples were generally within the European and Serbian regulatory limits. The levels of all the 123 analysed pesticides were below the limit of quantification (LOQ). Regarding PAH levels in honey, the highest content was found for naphthalene. The elevated levels of Hg and Cr and of PAHs in the pollen samples indicated air pollution. Pesticide residues in pollen, however, were below the LOQ. In nectar, metal levels were relatively similar to those in honey. Our results suggest that the investigated urban honey meets the regulatory requirements for metals, PAHs, and pesticides and is therefore safe for consumption.

AB  - Oblacinska' sour cherry, an autochthonous cultivar, is the most planted cultivar in Serbian orchards. Since fruit trees in temperate zone reward insects by producing nectar which 'quality' affects the efficiency of insect pollination, the aim of this study was analyzing of sugars and polyphenolics in floral nectar of 16 'Oblacinska' sour cherry clones with different yielding potential. The contents of sugars and sugar alcohols were analyzed by ion chromatography, while polyphenolic profile was established using liquid chromatography/mass spectrometry technique. Fourteen sugars and six sugar alcohols were detected in nectar samples and the most abundant were fructose, glucose, and sucrose. Eleven polyphenols were quantified using available standards, while another 17 were identified according to their exact masses and characteristic fragmentations. Among quantified polyphenols, rutin, naringenin, and chrysin were the most abundant in nectar. Principal component analysis showed that some polyphenol components (naringin, naringenin, and rutin) together with sugars had high impact of spatial distribution of nectar samples on score plot.

AB  - Assessment of microbiological quality of bee collected pollen is very important, because of its use as a supplement in the human diet. In this study, 26 samples collected from different location in Serbia were tested for the presence of mold through mycologial analysis. The presence of aflatoxin B1, one of the most dangerous and the most widespread mycotoxin was also determined. It was established that 10 of the investigated samples were contaminated with some genera or species of mold, but all of the investigated samples were contaminated with aflatoxin B1. Considering that there is no unique and official procedure for mycological analysis of bee collected pollen, these findings suggest the need for their establishment. Mycological analysis should be followed by mycotoxicological analysis since the absence of mold does not confirm the absence of aflatoxin B1 in bee pollen.

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.
