| 【目的】调查广西香蕉的农药残留情况,评估其农药残留风险。【方法】采用液相色谱/串联质谱(LC-MS/MS)和气相色谱-串联质谱(GC-MS/MS)法,对2024年在广西香蕉生产基地及市场采集的263份香蕉样品的农药残留进行了检测和定量,并结合食品安全指数法和危害物风险系数法进行联合风险评估。【结果】香蕉全果样品共中检出27种农药残留,果肉样品中检出8种农药残留,全果和果肉样品中检出率最高的农药分别是吡唑醚菌酯(54.8%)和吡虫啉(8.7 %)。所有检出农药的食品安全指数(IFS)均小于1,表明农药残留的安全性风险可接受；从危害物风险系数(R)的结果看,全果中的吡唑醚菌酯、苯醚甲环唑、甲基硫菌灵、吡虫啉和噻虫胺存在高预警风险,果肉中的甲基硫菌灵存在中度预警风险。【结论】吡唑醚菌酯、苯醚甲环唑、甲基硫菌灵、吡虫啉和噻虫胺这5种农药应被视为关键控制风险因素,在日常监管中持续监测。 |

| 【Objective】 To investigate the pesticide residue situation in Guangxi bananas and assess the risks associated with these residues.【Methods】Liquid chromatography-tandem mass spectrometry (LC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS) were utilized to analyze the pesticide residues in 263 banana samples procured from production bases and markets in Guangxi in 2024. The detected pesticides were risk-assessed using the index of food safety (IFS) method and the hazard risk coefficient (R) method. 【Results】The analysis revealed the presence of 27 pesticide residues in the whole fruit samples and 8 in the pulp samples. The most frequently detected pesticides in both whole fruit and pulp samples were pyraclostrobin (54.8%) and imidacloprid (8.7%), respectively. The Food Safety Index (IFS) for all detected pesticides was less than 1, indicating that the safety risk of pesticide residues was acceptable. From the results of the hazard risk coefficient (R), high warning risks were identified for pyraclostrobin, difenoconazole, thiophanate methylate, imidacloprid and clothianidin in whole fruit, while thiophanate methylate posed a moderate warning risk in pulp. 【Conclusions】These five pesticides should be considered as key control risk factors and continuously monitored in routine regulation. |
