    摘要:

    目的:研究桃胶中农药残留及风险。方法:基于液相色谱—串联质谱法(LC-MS/MS)建立桃胶中44种农药残留的定量分析方法,并对全国173份桃胶样品进行农药残留检测和风险评估分析。结果:基于LC-MS/MS农药残留检测方法的检出限(LOD)为0.05~1.80 μg/kg,定量下限(LOQ)为0.20~2.42 μg/kg,加标回收率为61.77%~119.48%。桃胶样品中共检出22种农药,农药总检出率为98.8%,平均每个样品检出农药次数为2.8次,苯醚甲环唑检出率最高(95%),其次是毒死蜱(54%)、多菌灵(34%)、呋虫胺(32%)、吡唑醚菌酯(19%)等。不同桃胶样品中苯醚甲环唑平均残留量最高为0.332 mg/kg,其次是呋虫胺(0.093 mg/kg)、多菌灵(0.061 mg/kg)、毒死蜱(0.033 mg/kg)。结论:桃胶中农药的残留与桃生产用药有关,其残留量总体处于低风险水平,推荐8—10月份采摘桃胶。

    Abstract:

    Objective: This study aimed to investigate the residues and risk assessment of pesticides in peach gum. Methods: The quantitative analysis of 44 pesticide residues in peach gum was established based on liquid chromatography tandem-mass spectrometry (LC-MS/MS), and the pesticide residues in 173 peach gum samples were detected as well as the risk assessment of pesticide residues. Results: The limits of detection (LOD) and the limits of quantification (LOQ) of 44 kinds of pesticides in this quantitative method were between 0.05~1.80 μg/kg and 0.20~2.42 μg/kg, respectively. Recoveries of these pesticides ranged from 61.77%~119.48%. In 173 peach gum samples, 22 out of 44 pesticides were detected and the total detection rate of pesticides in peach gum was 98.8%. The detection rate of difenoconazole was the highest (95%), followed by chlorpyrifos (54%), carbendazim (34%), furamethoxam (32%) and pyraclostrobin (19%). The average residue of difenoconazole in different peach gum samples was the highest (0.332 mg/kg), followed by furamethoxam (0.093 mg/kg), carbendazim (0.061 mg/kg) and chlorpyrifos (0.033 mg/kg). Conclusion: Pesticide residues in peach gum were related to the usage of pesticides in peach production and were at a low risk level. It is recommended to pick peach gum from August to October.
