摘  要：
[目的]建立鳗鱼、泥鳅、黄鳝和鲶鱼组织中5种苯甲酰脲类杀虫剂的气相色谱质谱联用(GC-MS)检测方法。[方法]样品组织经提取、净化等步骤,七氟丁酸酐(HFBA)衍生化,GC-MS分析。对衍生化条件进行了细致的探索。[结果]经验证,方法线性良好,检测限0.3~1.5μg/kg,定量限1.0~5.0μg/kg。在3个添加水平下,5种目标化合物在4种组织中的变异系数均小于10.3%,平均回收率81.5%~98.7%。并在实测样品中成功检测出目标化合物。[结论]该方法可用于鱼组织中目标化合物的检测。

摘  要：
[Aims ] A method for detection of 5 benzoylurea insecticide residues in eel, catfish, loach and monopterus tissues by gas chromatography-mass spectrometry was established. [Methods ] The residues of target compounds were extracted, cleaned up, derivatized with heptafluorobutyric anhydride(HFBA) and detected by GC-MS. Optimal conditions for the derivatization were investigated. [Results ] The linearity of the analytical method was excellent. The limit of detection(LOD) was 0.3-1.5 μg/kg, and the limit of quantification(LOQ) was 1.0-5.0 μg/kg. At three fortification levels, the average recoveries for this four kinds of samples ranged from 81.5 to 98.7%, and the relative standard deviation(RSD) were all below 10.3%. This method was successively applied to the determination of the five compounds in real samples from markets. [Conclusions ] The method is suitable for the simultaneous determination of five benzoylurea insecticide residues in fish tissues.
