| Summary: | Residues of pesticides and chemical toxins in water, crops, and food, which are a direct consequence of repeated, misplaced, and over-spraying of the crop during the growing season, seriously threaten the consumers' health. Therefore, the determination of residual toxins in drinking water sources is of crucial importance. After field studies on legal and illegal pesticides used in East Azerbaijan province, sampling was performed in four phases of identified water sources. Toxins and pesticides were extracted by air-assisted liquid-liquid microextraction and assessed using GC-MS. Following optimization of extraction conditions and device conditions, pH = 7, the salt content of 0.1 g, extraction time of 5 minutes, 5 suctions and 1,2,1,1-tetrachloroethane as the extraction solvent were selected as the optimal parameters. Under optimal conditions, a calibration diagram was drawn for the identified and extracted toxins. Malathion, diazinon, fenpropathrin, atrazine, and chlorpyrifos was traced in Tabriz water sources. |
