The urgent call for the control and regulation of pesticide usage arose from the adverse health effects associated with their excessive and wrong application mostly in the agricultural field. The uncontrolled use of pesticides has been proved to affect the environment because of their ability to accumulate in different environmental resources such as water and soil. Fenazaquin is one of the mostly used pesticides in the agricultural field known by its adverse health effects. In this study, the previously mentioned pesticide "fenazaquin" was analyzed in two different kind of environmental samples: irrigation canal water and soil samples using a highly accurate gas chromatography mass spectrometer (GCMS). In the first step of the study, the limit of qualification (LOD), limit of quantification (LOQ), and relative standard deviation (RSD) were determined and calculated to be 0.04 mg/L, 0.14 mg/L and 10.2%, respectively. In the following step, the samples were spiked at different concentrations using low volumes of high concentration stock solution, to ensure the real effects of the sample matrices were observed. All measurement were performed by applying the adequate temperature program of the sensitive analytical instrument GCMS. The results obtained using the classical recovery procedure was satisfactory but matrix matching calibration strategy was used to improve the percent recoveries to almost 100%. Thus, this study explains the possibility of fenazaquin determination in two different environmental samples using the classical recovery and matrix matching strategies. Irrigation canal water and soil samples are on a high contamination risk from the pesticides used in the agricultural field.
