This study investigated seven pesticides in vegetables produced in rural South-western Uganda to determine their suitability for human consumption. Pesticide residue concentrations (ppm) were determined using QuEChERS method, LC-MS/MS, GC-MS/MS and UV-Vis. Cypermethrin, dimethoate, metalaxyl, profenofos, malathion, dichlorvos and mancozeb concentrations detected in sprayed samples ranged between 0.00403 and 0.05350, 0.17478-62.60874, 0.12890-3.55681, 0.00107-0.59722, 0.03144-0.63328, 0.00240-0.34102 and 0.00001-0.00244, respectively. The residues exceeded MRLs in sprayed samples (59.52%), unsprayed samples (18%) and market samples (8%). The quality index of the market vegetables was found to be optimal (14.29%), good (75%), adequate (3.57%) and inadequate (14.29%). Pesticide residues may lower food quality and pose risk to human health. Therefore, regulation and monitoring pesticide residues in vegetables produced in south-western Uganda in order to avoid harmful effects on human health would be paramount.
本研究旨在调查乌干达西南部农村地区生产的蔬菜中的七种农药，以确定其是否适合人类食用。采用 QuEChERS 方法、LC-MS/MS、GC-MS/MS 和 UV-Vis 法测定了农药残留浓度（ppm）。在喷雾样品中检测到的氯氰菊酯、乐果、甲霜灵、丙溴磷、马拉硫磷、敌敌畏和代森锰锌的浓度在 0.00403 至 0.05350、0.17478 至 62.60874、0.12890 至 3.55681、0.00107 至 0.59722、0.03144 至 0.63328、0.00240 至 0.34102 和 0.00001 至 0.00244 之间。在喷雾样品（59.52%）、未喷雾样品（18%）和市场样品（8%）中，残留量超过了 MRLs。市场蔬菜的质量指数被认为是最佳的（14.29%）、良好的（75%）、足够的（3.57%）和不足的（14.29%）。农药残留可能会降低食品质量，对人类健康构成威胁。因此，为了避免对人类健康造成有害影响，对乌干达西南部生产的蔬菜中的农药残留进行监管和监测至关重要。
