【摘要】 用氣相色譜-質(zhì)譜法對雙孢蘑菇（Agaricus bisporus）和香菇（Lentinula edodes）中67種農(nóng)藥進(jìn)行檢測。樣品經(jīng)乙腈均質(zhì)提取,鹽析除水,氨基柱凈化后用氣相色譜-質(zhì)譜儀分析,在選擇離子監(jiān)測模式下以特征離子的保留時間定性定量測定67種農(nóng)藥。在添加農(nóng)藥標(biāo)準(zhǔn)品濃度為0.05、0.10和0.25 mg/kg水平上,大多數(shù)農(nóng)藥的平均回收率在70%120%之間,檢出限在0.010.5μg/kg之間。

【Abstract】 Gas chromatography-mass spectrometry（GC-MS） was used to determine the levels of 67 pesticide residues in fruit bodies of Agaricus bisporus and Lentinula edodes.Fresh mushroom fruit bodies for GC-MS analysis were first homogenized,and a solution containing standard amounts of 67 pesticides at three different concentrations（0.05,0.10 and 0.25 mg/kg） were added.After thorough mixing,the homogenates were extracted with acetonitrile and purified using a Cleanert NH2-SPE column.Pesticides were determi...
