    摘要:

    氯氰菊酯是一种拟除虫菊酯杀虫剂,因其高效、低毒等优点被广泛用于蔬菜种植中,因此造成了大量残留。目前,氯氰菊酯在蔬菜热加工过程中的降解行为尚不清楚。作者构建了茼蒿中氯氰菊酯和3-苯氧基苯甲酸(3-PBA)的高效液相色谱(high performance liquid chromatography,HPLC)同时检测方法,研究了茼蒿热加工过程中残留的氯氰菊酯的降解行为。结果表明,以体积分数0.1%的乙酸-乙腈为提取溶剂、超声提取15 min、100 mg石墨化炭黑(GCB)净化样品时提取效果最佳,回收率为93%~106%。对茼蒿进行热加工处理后发现,烫漂使氯氰菊酯降解了16.87%,未检测到3-PBA;炒制使氯氰菊酯降解了76.76%,但有少量的3-PBA生成。通过质谱共检测到3种降解产物,结合理论计算推测出氯氰菊酯的降解途径。该研究可为氯氰菊酯及其代谢物的膳食暴露评估提供依据。

    Abstract:

    Cypermethrin, a pyrethroid insecticide, is widely used due to its high efficiency and low toxicity, leading to significant residues in vegetables. However, its degradation behavior during thermal processing of vegetables remains unclear. This study developed a simultaneous high performance liquid chromatography (HPLC) method for the determination of cypermethrin and 3-phenoxybenzoic acid (3-PBA) in crown daisy to investigate the degradation of cypermethrin residues during thermal processing. The results showed that the optimal extraction conditions for cypermethrin were achieved using 0.1% acetic acid-acetonitrile as the extraction solvent, ultrasonic extraction for 15 minutes, and sample purification with 100 mg of graphitized carbon black (GCB), resulting in recoveries between 93% and 106%. After thermal processing, blanching caused a 16.87% degradation of cypermethrin, with no 3-PBA detected, while stir-frying led to a 76.76% degradation of cypermethrin, with trace amounts of 3-PBA detected. Three degradation products were detected by mass spectrometry, and combined with theoretical calculations, the degradation pathway of cypermethrin was suggested. This study can provide a basis for the dietary exposure assessment of cypermethrin and its metabolites.
