Comparison of Methods for Bifenthrin Residues Determination in Fermented Wheat Samples
Djordjevic, Tijana; Djurovic, Rada; Gajic Umiljendic, JelenaEfficiency of three different sample preparation methods for GC/MS determination of bifenthrin residues in wheat (Triticum spelta) samples fermented by Lactobacillus plantarum was tested. The first method was based on a ... -
Determination of Atrazine, Acetochlor, Clomazone, Pendimethalin and Oxyfluorfen in Soil by a Solid Phase Microextraction Method
Djurovic, Rada; Gajic-Umiljendic, Jelena; Djordjevic, TijanaA solid phase microextraction (SPME) method for simultaneous determination of atrazine, acetochlor, clomazone, pendimethalin and oxyfluorfen in soil samples was developed. The method is based on a combination of conventional ... -
Determination of Copper-Based Fungicides by Flame Atomic Absorption Spectrometry Using Digestion Procedure with Sulfuric and Nitric Acid
Milinovic, Jelena; Djurovic, RadaCopper-based fungicides can be effectively digested by treatment with a mixture of concentrated sulfuric and nitric acid in exactly 15 minutes for the rapid determination via copper using flame atomic absorption spectrometry ... -
Effects of Organic Matter and Clay Content in Soil on Pesticide Adsorption Processes
Djurovic, Rada; Gajic-Umiljendic, Jelena; Djordjevic, TijanaThe effect of organic matter and clay content on the adsorption of atrazine, acetochlor, clomazone, pendimethalin and oxyfluorfen in soil samples was studied. In order to determine whether and to what degree different ... -
Headspace Solid Phase Microextraction in Pesticide Residues Analysis: 1. Optimisation of Extraction Conditions
Djurovic, Rada; Milinovic, Jelena; Markovic, Mirjana; Markovic, DraganThe method of headspace solid phase microextraction (HS/SPME) was successfully used in a simultaneous multicomponent analysis of hexachlorobenzene (HCB), tefluthrin, heptachlor, aldrin, chlorpyrifos, fenthion and bifenthrin ... -
Headspace Solid Phase Microextraction in Pesticide Residues Analysis: 2. Apple Samples
Djurovic, Rada; Milinovic, Jelena; Markovic, Mirjana; Markovic, DraganHeadspace solid phase microextraction method (HS/SPME), optimised previously for pesticide water solutions, was applied to trace residues of the pesticides chlorpyrifos, fenthion and bifenthrin in apple samples. One-hour ... -
Maize, Sunflower and Barley Sensitivity to the Residual Activity of Clomazone in Soil
Gajic Umiljendic, Jelena; Jovanovic-Radovanov, Katarina; Radivojevic, Ljiljana; Santric, Ljiljana; Djurovic, Rada; Djordjevic, TijanaSensitivity of maize, sunflower and barley to clomazone residues in loamy soil was assessed in the study using bioassay. Clomazone was applied at a series of concentrations from 0.12 to 12 mg a.i./kg of soil. After 14 ... -
Methods for Determination of Pesticide Adsorption Properties and Examination of Their Mobility in Soil
Djurovic, RadaPesticide destiny in soil depends on a number of factors, as well as on presence and intensity of the processes such as adsorption, degradation, evaporation, rinsing and leaching. Since adsorption processes govern ... -
Multiresidue Analysis of Pesticides in Soil by Liquid-Solid Extraction Procedure
Djurovic, Rada; Djordjevic, Tijana; Radivojevic, Ljiljana; Santric, Ljiljana; Gajic Umiljendic, JelenaA multiresidue method for simultaneous determination of four pesticides (diazinon, acetochlor, aldrine and carbofuran) belonging to different pesticide groups, extracted from soil samples, is described. The method presented ... -
The Processes that Determine the Fate of Pesticides in Soil
Djurovic, RadaPesticides are an inevitable part of the environment, because due to the intensive use their remains are frequently detected in nature, particularly in the soil. Regardless the way pesticides get into the soil, their ... -
Solid Phase Microextraction (SPME) in Determination of Pesticide Residues in Soil Samples
Djurovic, RadaThe basic principles and application possibilities of the methods based on solid phase microextraction (SPME) in the analysis of pesticide residues in soil samples are presented in the paper. The most important experimental ...
