Abstract
This work describes the development of an analytical method for determining the mobility of some organophosphorus and azole group pesticides. The chromatographic and mass spectrophotometric parameters were optimized. The target pesticides were recovered quantitatively (79.3–95.6%) with a relative standard deviation less than 8.5% at the optimum conditions of the extraction. The limits of detection of the target pesticides were found to be in the range of 0.16 to 1 . 14 µ g kg − 1 with a correlation coefficient ( r) > 0 . 9955 . The method was validated in the target environmental matrices by the analysis of a spiked soil sample. The proposed method was successfully applied for the determination of pesticides in vineyard soil samples and statistically evaluated.
