摘要依据行业标准NY/T 761—2008,采用气相色谱法,对蔬菜中六六六、腐霉利、联苯菊酯、高效氯氟氰菊酯、氯菊酯、氯氰菊酯的残留量进行测量不确定分析,在标准品、标准溶液配制、样品称量、前处理过程、标准溶液峰面积、样品溶液峰面积和回收率7个方面进行测量不确定度的评定。结果显示:在0.08mg/kg添加水平下,α-六六六、β-六六六、γ-六六六、δ-六六六、腐霉利、联苯菊酯、高效氯氟氰菊酯、氯菊酯、氯氰菊酯合成的不确定度分别为:2.63%、3.01%、2.45%、2.69%、2.33%、1.83%、2.41%、3.34%、2.84%,影响测量不确定度的主要来源为回收率、样品溶液峰面积、标准溶液峰面积。标准溶液的配制、前处理过程对合成不确定度较小的目标物亦不能忽视。

Abstract：According to NY/T 761—2008, the uncertainty of HCH, pythium, bifenthrin, beta cypermethrin, permethrin and cypermethrin in vegetables were evaluated by gas chromatography. The uncertainty of the detection method was evaluated from seven aspects: standard purity, standard solution, sample weighing, pretreatment process, standard solution peak, sample solution peak and recovery. The results showed that: at the spiking level of 0.08mg/kg, the relative combined standard uncertainty of α-HCH, β-HCH, γ-HCH, δ-HCH, Pythium, bifenthrin, beta Cypermethrin, permethrin and cypermethrin were 2.63%, 3.01%, 2.45%, 2.69%, 2.33%, 1.83%, 2.41%, 3.34% and 2.84%, respectively. The main factors of uncertainty were recovery, sample solution peak and standard solution peak. Standard solution and pretreatment process can not be ignored especially for the target with less measurement uncertainty.
