于2018年在湖南长沙、湖南张家界、浙江兰溪等12地开展除虫脲的最终残留试验，并在其中湖南长沙、江西高安、广西南宁、福建漳州等4地进行除虫脲的残留消解试验，采用高效液相色谱–串联质谱法（HPLC–MS/MS）测定除虫脲在柑橘全果和柑橘果肉中的残留量，并进行除虫脲的膳食安全风险评估。结果表明：柑橘样品先采用乙腈超声提取，再经PSA和无水硫酸镁净化，最后用HPLC–MS/MS分析测定，外标法定量，柑橘全果和柑橘果肉中除虫脲的添加水平为0.01、0.10、1.00、5.00 mg/kg时，平均回收率分别为89%～102%和76%～99%，相对标准偏差分别为7%～11%和8%～9%；除虫脲在柑橘全果和柑橘果肉中的定量限均为...

The final residue experiment of diflubenzuron in citrus(Citrus reticulata Balanco)was carried out in twelve cities(Changsha,Zhangjiajie,Lanxi,etc)in China in 2018.And the residue dissipation dynamics experiment of diflubenzuron was studied in Changsha,Gaoan,Nanning and Zhangzhou.The residue of diflubenzuron in citrus whole fruit and pulp were investigated by high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)method,and then the risk assessment for dietary safety risk of diflubenzuron in citrus was studied based on the residue data.The results showed that citrus samples ...
