摘要：The application of pesticides in agricultural activities is well known; however, their extensive or improper application may pollute water resources. As a consequence, monitoring of their residue levels in the water is a necessity. In this study, a rapid and sensitive analytical method has been validated according to the European Union SANCO/12495/2011 guidelines and the requirements of the norm V03-110 and those of the NF T 90-210 for the determination of Carbaryl pesticide in water samples using liquid chromatography-tandem mass spectrometry (LC–MS/MS). This work will help us to quantify in an exact way our samples and to be able to ensure the quality and the healthiness of the water. The linear calibration function is considered acceptable in the area studied [10 – 160 μg/Kg] for the pesticide studied. The accuracy of the quantification limit presupposed 10 μg/Kg was checked and the average recovery obtained by the LC–MS/MS method for both MRM Carbaryl pesticides ranged from 89.53 to 101.72 % which is in the acceptance range of the LAB GTA 26. The trueness, fidelity and accuracy of the method were verified for three levels of concentrations 10, 30 and 120μg/Kg. The method is easy, with low consumption of reagents, is characterized by reliability, sensitivity and therefore is suitable for the monitoring the levels of Carbaryl pesticide residues in water.
