摘要:

为探明唑虫酰胺和氟啶虫酰胺在茶叶中的消解动态和最终残留情况,评估使用该药剂防治害虫可能产生的膳食风险,本文采用超高效液相色谱-串联三重四极杆质谱(UPLC-MS/MS)进行分析,外标法定量。结果表明,该方法线性良好,氟啶虫酰胺在茶叶(鲜)及茶叶(干)中的平均回收率分别为88%~96%和90%~93%,相对标准偏差(RSD)分别为3.9%~6.0%和2.3%~2.9%;唑虫酰胺在茶叶(鲜)及茶叶(干)中的平均回收率分别为81%~88%和85%~92%,RSD分别为2.2%~4.2%和2.1%~5.3%。膳食风险评估表明,唑虫酰胺、氟啶虫酰胺的国家估计每日摄入量(NEDI)分别为0.147 61 mg与2.395 72 mg,分别占每日允许摄入量(ADI)的39.1%和53.5%,对一般人群无不可接受风险。因此,在规范施药条件下,唑虫酰胺和氟啶虫酰胺在茶叶中属于低残留农药,且膳食摄入风险较低。本研究为唑虫酰胺和氟啶虫酰胺在茶叶上的科学合理使用提供了数据支持。

Abstract:

In order to investigate the degradation dynamics and final residues of tolfenpyrad and flonicamid in tea, and to clarify the possible dietary risks caused by using tolfenpyrad and flonicamid in pest control, the samples were analyzed by ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry (UPLC-MS/MS), with an external standard method. The results showed that the analysis method had good linearity. The average recovery rates of flonicamid in fresh tea and dry tea were 88%-96% and 90%-93%, respectively, with a relative standard deviation (RSD) of 3.9%-6.0% and 2.3%-2.9%, respectively. The average recovery rate of tolfenpyrad in fresh tea and dry tea was 81%-88% and 85%-92%, respectively, and the RSD was 2.2%-4.2% and 2.1%-5.3%, respectively. Dietary risk assessment showed that the national estimated daily intake (NEDI) of tolfenpyrad and flonicamid were 0.147 61 and 2.395 72 mg, respectively, accounting for 39.1% and 53.5% of the acceptable daily intake (ADI), and there was no unacceptable risk for the general population. Therefore, under the standard application conditions, tolfenpyrad and flonicamid belong to low residue pesticides in tea, and the risk of dietary intake is low. This study provided data support for the scientific and rational use of tolfenpyrad and flonicamid in tea.
