o:6394 Sorption Behavior of Selected Pesticides in Alluvial Aquifers en There are approximately 1000 registered products for plant protection with over 300 different active ingredients in Serbia. Due to their extensive use in agriculture, they may be detected in all environmental mediums. Therefore, they’re monitored in air, water and soil, but also in food and tissues. Concentrations of 15 pesticides in surface and groundwaters in Serbia have been monitored from the year 2009 to 2014, in sampling campaigns conducted by the Jaroslav Cerni Institute for the Development of Water Resources. The results showed that the selected pesticides were detected in almost 34% of surface water samples, and in 33% of groundwater samples. All of the detected pesticides had very low concentrations in both surface and groundwater samples (lower than 0.1 pg/L), with a few exceptions. The most frequently detected pesticides were carbendazim and atrazine. These two pesticides have been selected for further analyses of sorption behavior in the sediment, with one additional pesticide for these experiments: carbofuran. In this paper, sorption coefficients for Danube sediment samples collected in Kovin-Dubovac area were analyzed. Sorption coefficient in these samples was highest for carbofuran, and lowest for atrazine. Lack of information on organic matter content and pH of the sediment used in sorption experiments lead to the further research of sorption behavior dependence on various factors of the three selected pesticides in literature data. Regression analysis with a large number of literature data was carried out, with regression equations as results. These results were compared to the ones gained in sorption experiments. pesticides, sorption coefficient, multiple regression analysis 1552100 978-86-82565-46-8 2024-12-06T08:55:50.305Z 44 no 46 Nevena Živančev Faculty of Technical Sciences, University of Novi Sad, Republic of Serbia Milan Dimkić Jaroslav Černi Institute for the Developement of Water Resources, Belgrade, Serbia, person Marina Radišić University of Belgrade, Faculty of Tehnology and Metallurgy, Belgrade, Serbia person Mila Laušević University of Belgrade, Faculty of Tehnology and Metallurgy, Belgrade, Serbia person Marija Perović Jaroslav Černi Institute for the Developement of Water Resources, Belgrade, Serbia, person 0000-0003-2045-001X Srđan Kovačević Faculty of Technical Sciences, University of Novi Sad, Republic of Serbia person application/pdf 3737132 https://unilib.phaidrabg.rs/o:6394 no yes 1 70 92000004 71A04 IWA Specialist Groundwater Conference, Conference Proceedings and Book of Abstracts, 09-11 June 2016.
