Determination of Atraton in Irrigation Canal Water and Soil Samples by Gas Chromatography Mass Spectrometry

Abstract

Benefits such as disease prevention, improved food quality and yield are attributed to pesticide usage but severe health effects that arise from their wrong usage and continual accumulation in the environment has called for constant monitoring. This study was performed to determine atraton in irrigation canal water and soil samples by gas chromatography mass spectrometry with high accuracy. Satisfactory analytical figures of merit were obtained for the analyte. Under the optimum conditions, the analyte was not detected in the analysis of irrigation canal water and soil samples and was therefore spiked at different concentrations within the linear calibration range. In order to increase the accuracy of quantifying the analyte in the complex soil matrix, calibration standards were prepared in soil extracts. The percent recoveries calculated for spiked irrigation canal water samples by calibration standards prepared in ultrapure water ranged between 97.62.2 % and 109.60.6 %. The percent recoveries calculated for spiked soil samples using the calibration standards prepared ranged between 90.3 2.3 % and 103.2 8.2 %. The linear dynamic range was obtained in the concentration of 0.25 -10 mg/L. The values for LOD, LOQ and %RSD were respectively 0.08 mg/L, 0.26 mg/L and 8.0 %.
