o:6427 Methods using passive sampling techniques in sediment en Sampling is the most important step of any analytical procedure. Errors committed at this stage cannot be corrected later during the analysis. There is a different specific methods, which depend on the nature of the analyte and their concentration levels. Solutions for this situation are methods of passive sampling and extraction of analytes, which involve measurement of the concentration of any analyte as a weighted average over the sampling and/or extraction time. The concentration of the analyte is integrated over the whole exposure time, making such a method immune to accidental, extreme variations of pollutant concentrations. Information obtained in this way is a suitable means of obtaining a long-term overview ofpollutant levels in a environmental compartments. Techniques like Solid Phase Micro Extraction (SPME), Low Density Polyethylene- (LDPE), Silicon rubber- (PDMS) and POM- Solid Phase Extraction are applied to determine the pore water concentrations. TENAX extractions are used to estimate the available fraction, and In-vitro Passive Sampling (IVPS) gives an estimate of both pore water and available concentrations. Consequently, the partition coefficients of the compounds of interest for the available fraction in the sediment the are determined as well. The availability concept and how the different methods contribute to obtaining information on availability for uptake are discussed. passive sampling, sediment, SPME, TENAX, POM, PDMS, LDPE, IVPS 1552100 978-86-7672-172-6 2024-12-06T13:27:16.501Z 44 no 46 Maja Stupavski Faculty of Technical Sciences, Department of Environmental engineering and occupational safety, University of Novi Sad, Serbia Mirjana Vojinović-Miloradov Faculty of Technical Sciences, Department of Environmental engineering and occupational safety, University of Novi Sad, Serbia person Maja Turk-Sekulić Faculty of Technical Sciences, Department of Environmental engineering and occupational safety, University of Novi Sad, Serbia person Jelena Radonić Faculty of Technical Sciences, Department of Environmental engineering and occupational safety, University of Novi Sad, Serbia person Jelena Kiurski-Milošević Higher Technology School of professional Studies, Zrenjanin, Serbia person Srđan Kovačević Faculty of Technical Sciences, Department of Environmental engineering and occupational safety, University of Novi Sad, Serbia person Zoran Čepić Faculty of Technical Sciences, Department of Environmental engineering and occupational safety, University of Novi Sad, Serbia person Marija Okuka Faculty of Technical Sciences, Department of Environmental engineering and occupational safety, University of Novi Sad, Serbia person 0000-0003-2045-001X application/pdf 6047629 https://unilib.phaidrabg.rs/o:6427 no yes 1 70 92000004 71A04 Proceedings of II International Conference “Ecology of urban areas 2012”, 15th October 2012, Ečka - Zrenjanin 181 186 Faculty of Technical Sciences “Mihajlo Pupin”, Zrenjanin 2012
