| 摘 要： | 建立了氟唑菌酰羟胺和苯醚甲环唑在香蕉全果和果肉中的超高效液相色谱-串联质谱检测方法,在云南进行了规范残留试验,研究了氟唑菌酰羟胺和苯醚甲环唑在香蕉上的残留消解行为并进行了长期膳食暴露风险评估。结果表明：在0.01~1 mg/kg添加范围内,氟唑菌酰羟胺和苯醚甲环唑在香蕉全果和果肉中的平均回收率分别为75%~115%和78%~106%,相对标准偏差分别为1.0%~5.0%和1.0%~5.3%,方法最低检出浓度均为0.01 mg/kg。氟唑菌酰羟胺和苯醚甲环唑在云南香蕉中的半衰期分别为16.9、20.4 d。施药后21、28、35 d收获的香蕉中,氟唑菌酰羟胺残留量均低于0.01 mg/kg,苯醚甲环唑在香蕉中的最高残留量为0.048 mg/kg。风险评估结果表明,香蕉中氟唑菌酰羟胺和苯醚甲环唑残留长期膳食摄入风险较低,处于安全水平。该方法准确度高,灵敏度高,线性良好;残留消解试验及膳食风险评估为氟唑菌酰羟胺和苯醚甲环唑在香蕉上的合理安全使用提供科学依据。

| Abstract: | The method for the determination of pydiflumetofen and difenoconazole residues in banana fruit and flesh was established. The upervised residue trial was carried out in Yunnan. The residual digestion behavior and dietary intake risk in banana were analyzed. Average recoveries of pydiflumetofen and difenoconazole in banana fruit and flesh were found in the range of 75%-115% and 78%-106% at the three spiking levels from 0.01 to 1 mg/kg with relative standard deviations of 1.0%-5.0% and 1.0%-5.3%. The limit of quantification (LOQ) of instrument for pydiflumetofen and difenoconazole was 0.01 mg/kg. The results demonstrated that the half-life of pydiflumetofen and difenoconazole for banana was 16.9 d and 20.4 d in Yunnan, respectively. The residue of pydiflumetofen was <0.01 mg/kg and the maximum residue of difenoconazole in banana was 0.048 mg/kg sprayed after 21, 28, 35 d. Risk assessments indicated that the long-term dietary intake risk of pydiflumetofen and difenoconazole in banana was low and at a safe level. The method shows high accuracy, high sensitivity and good linearity. The experiments would provide scientific basis for evaluating the safety and rationality of using pydiflumetofen and difenoconazole in banana. |
