Cucumber (Cucumis sativus L.) is the world's most widely consumed salad vegetable, and it is frequently treated with pesticides to prevent pest and disease outbreaks. Pesticide residues in food commodities impede trade and pose a major health risk. Prior to residue estimation, the QuEChERS approach was validated utilising criteria such as limit of detection, limit of quantitation, linearity, accuracy, and precision. The residues of carbendazim, cypermethrin, ethion, profenofos, quinalphos, and triazophos were examined using a Gas Chromatograph equipped with an Electron Capture Detector or a Flame Photometric Detector and a high-performance liquid chromatography coupled to a photo diode array. The initial deposits of carbendazim, cypermethrin, ethion, profenofos, quinalphos, and triazophos at the prescribed dose were 1.235, 0.407, 0.817, 0.960, 0.628, and 0.985 mg/kg, respectively, with a pre-harvest interval of 5.58-11.30 days. According to the consumer risk evaluation data, the Hazard Quotient is less than one, and the Theoretical Maximum Dietary Intake is less than the Maximum Permissible Intake and Maximum Residue Limit, both of which are considered safe for human consumption at the authorised dose.
黄瓜（ Cucumis sativus L.）是世界上最广泛食用的沙拉蔬菜，为了防止病虫害的爆发，它经常被使用农药处理。食品中的农药残留阻碍了贸易，并构成了重大的健康风险。在进行残留估计之前，使用了 QuEChERS 方法进行验证，其标准包括检测限、定量限、线性、准确度和精密度。使用配备电子俘获检测器或火焰光度检测器的气相色谱仪以及与光电二极管阵列相连的高效液相色谱法来检测多菌灵、氯菊酯、乙硫磷、丙溴磷、喹硫磷和三唑磷的残留。在规定剂量下，多菌灵、氯菊酯、乙硫磷、丙溴磷、喹硫磷和三唑磷的初始沉积量分别为 1.235、0.407、0.817、0.960、0.628 和 0.985mg/kg，收获前间隔为 5.58-11.30 天。根据消费者风险评估数据，危害系数小于一，理论最大膳食摄入量低于最大允许摄入量和最大残留限量，在授权剂量下，这两者都被认为是安全的人类食用。
