AB  - Cilj istraživanja je praćenje sudbne tiametoksama i klotianidina u biljkama suncokreta, nakon tretiranja semena ovim neonikotinoidom (preparatom Cruiser 600 FS). U ogledu su korišćeni hibridi suncokreta Oliva i Novak. Praćenje degradacije tiametoksama i metabolita klotianidina, je rađeno u cilju ispitivanja vremena razgradnje i njihovog prisustva u različitim fazama razvoja biljke (2 para pravih listova, 6 listova, zvezda, butonizacija i potpuno cvetanje). Metodom tečne hromatografije sa tandem masenom spektrometrijom (LC-MS/MS) uz upotrebu karbofurana-D3 kao internog standarda, nakon QuEChERS ekstrakcije uzoraka biljke suncokreta, urađeno je određivanje ostataka tiametoksama i klotianidina. Nakon obrade podataka, dobijeni su podaci koji ukazuju da je do faze potpunog cvetanja došlo do razgranje neonikotinoida, odnosno da nije bilo njihove detekcije nakon faze butonizacije.
AB  - The goal of this study is to monitor the fate of thiamethoxam and clothianidin, in sunflower plants, after treating the seeds with this neonicotinoid (Cruiser 600 FS). Olive and Novak sunflower hybrids were used in the experiment. Monitoring of degradation of thiamethoxam and clothianidin was done in order to examine the time of degradation and their presence in different phases of the plant (2 pairs of true leaves, 6 leaves, stars, budding and full flowering). Thiamethoxam and clothianidin residues were determined by liquid chromatography tandem mass spectrometry (LC-MS/MS) using carbofuran-D3 as an internal standard, after the QuEChERS extraction of sunflower plant samples. Obtained data indicate that the neonicotinoids branched to the stage of complete flowering, ie that they were not detected after the budding phase.

AB  - The interest in tropane alkaloids (TA) as food contaminants is increasing. A sensitive and selective LC-MS/MS method was applied for the analysis of corn puff samples from the Serbian market. Only atropine was quantified in 22% of the samples. In case of scopolamine, although not quantified, it was detected in 22% of the samples. Whether the acute reference dose (ARfD) could be exceeded was checked on a case-by-case basis for the individual products under assessment. Due to their low body weight and relatively high snack consumption, preschool children were at the highest risk of TA exposure. Assuming that the average consumption is 50 g of corn puffs per day, the sample with the highest concentration of TAs (2.05 µg/kg, 1.58 μg/kg of atropine) could contribute with 32.0% to the ARfD, of which 24.7% owing to atropine. If the same amount of corn puffs is consumed by older age classes, corresponding exposure contributions to the ARfD would progressively decline, down to 8.4% for adult population. The study revealed no health risk from TAs exposure through the consumption of the corn puffs in Serbian population.

Atropin je kvantifikovan u 22% uzoraka. U slučaju skopolamina, koji nije kvantifikovan, detektovano je u 22% uzoraka. Da li može doći do prekoračenja akutne referentne doze provereno je za svaki pojedinačni proizvod koji je uvršten u procenu. Mala telesna masa i relativno velike konzumirane količine snek-proizvoda ističu predškolsku decu kao grupu u najvećem riziku od izloženosti tropanskim alkaloidima. Pod pretpostavkom o konzumiranju 50 grama kukuruznog flipsa dnevno, uzorak s naj­ većom koncentracijom tropanskih alkaloida (2,05 µg/kg, 1,58 mg/kg atropina) može doprineti sa 32,0% od akutne referentne doze, od čega 24,7% odgovara atropinu. Ukoliko istu količinu kukuruznog flipsa konzumiraju starije uzrasne grupe, doprinos sledstvene izloženosti tropanskim alkaloidima bi progresivno opadao do 8,4% za odraslu populaciju. Studija nije ukazala na zdravstveni rizik usled izloženosti tropanskim alkaloidima putem konzumiranja kukuru­ znog flipsa za populaciju u Srbiji.

AB  - Based on the number of individuals and percentage of encounters in the studied areas, it is concluded that ground beetles (Coleoptera: Carabidae) stand out in comparison to other beetles, which is proved by the qualitative and quantitative composition of the collected fauna (51 species and 4,420 individuals) in the field of wheat, sugar beet and maize. Starting from the domination of geobiotic insects which spend most of their life in soil and manifest their imaginal activity on the surface of soil, the method of "Barber's traps" was applied. Within this family the dominant and subdominant species during research were Anchomenus dorsalis, Poecilus cupreus, Harpalus rufipes, Calosoma auropunctatum, Harpalu distinguendus and many others. 24 carabids species were determined using the COI mtDNA, i.e. 8 species which don't have reference sequence in the gene bank were determined and this contributes to the global bar-code database. The representatives of ground beetle family are of certain economic significance as well. They can appear as pests; on the other hand, they are known to be very beneficial i.e. as regulators of number of harmful insects as reported in numerous research papers of various authors.
