Özet
Pesticides, which accumulate in the ecosystem at high concentrations, interfere with the food chain of life forms and cause significant damage to them. The continuous increase in soil and water pollution due to the extensive use of pesticides has made it necessary to develop effective analytical methods to detect pesticides and to continuously monitor the level of residues with these methods. In this study, an analytical method for the detection of chlorsulfuron and pendimenthalin in soil matrix was developed and validated. The soil sample was fortified with a known quantity of pesticides at three different concentration levels (0.01, 0.05 and 0.1 mg/kg) and the analytes were extracted via a modified QuEChERS method. Recovery studies were performed with 5 different modified QuEChERS methods. Better recoveries were obtained in T4 method (extraction with 266.6 mg MgSO4, 66.6 mg NaCl, 66.6 mg TSCD and 33.3 mg DHS, d-SPE cleanup with 300 mg MgSO4 and 100 mg PSA). The recoveries were in the range 70–120 %, with relative standard deviation (RSD)values lower than 15 %. Chlorsulfuron and pendimenthalin of Limits of detection (LODs) were 0.96 and 1.30 μg kg−1 and limits of quantification (LOQs) were 3.19 and 4.34 μg kg−1, respectively.
