Survey on Pesticide Residues in the Chinese Herbs (II)

以氣相層析儀（附電子捕獲式檢出器）檢測市售人參、番瀉葉、茯苓、桂皮、甘草中藥材中有機氣農藥之殘留量。檢測項目包括α-BHC、β-BHC、γ-BHC、ρ,ρ'-DDT、Aldrin、Dieldrin、Heptachlor、Endrin、Heptachlor epoxide等九種，最低檢出量分別為：α-BHC 9.0 ppb、β-BHC 9.0 ppb、γ-BHC 10.0 ppb、ρ,ρ'-DDT 15.0 ppb、Aldrin 9.0 ppb、Dieldrin 11.0 ppb、Heptachlor 11.0 ppb、Endrin 12.0 ppb、 Heptachlor epoxide 11.0 ppb，平均添加回收率介於84.0~92.7%之間。經本分析方法檢測，20件番瀉葉檢體中，檢出α-BHC者15件，檢出β-BHC者3件，檢出γ-BHC者4件，其殘留量分別為α-BHC 0.009~0.022ppm；β-BHC 0.009~0.013ppm；γ-BHC 0.011~0.016ppm。20件人參檢體中，檢出α-BHC者14件，檢出β-BHC者6件，檢出γ-BHC者6件，其殘留量分別為：α-BHC 0.013~0.993ppm；β-BHC 0.014~0.078ppm；γ-BHC 0.010~0.195ppm。另桂皮、甘草及茯苓中藥材共60件檢體均未檢出上述九種有機氯農藥。"

For this survey, 100 samples of five marketed Chinese herbs including Ginseng Radix, Sennae Folium, Cinnamonomi Cortex, Poria and Glycyrrhizae Radix were randomly collected from Chinese herb stores in Taipei City and detected by GC/ECD.Nine Organic Chlorinated Hydrocarbon pesticides including α-BHC, β-BHC, γ-BHC, Heptachlor, Aldrin, Heptachlor Epoxide, Dieldrin, Endrin, and ρ,ρ'-DDT were investigated.The detection limits were shown as 9.0 ppb for α-BHC, 10.0 ppb for β-BHC, 12.0 ppb for γ-BHC, 11.0 ppb for Heptachlor, 9.0 ppb for Aldrin, 11.0 ppb for Heptachlor Epoxide, 11.0 ppb for Dieldrin, 12.0 ppb for Endrin, and 15.0 ppb for ρ,ρ'-DDT respectively. The recoveries are 86.7~92.5% for α-BHC, 85.5~91.1% for β-BHC, 87.0~92.3% for γ-BHC, 87.8~89.1% for Heptachlor, 87.3~92.7% for Aldrin, 85.1~92.3% for Heptachlor Epoxide, 84.0~89.3% for Dieldrin, 87.1~92.3% for Endrin, and 88.3~91.7% for ρ,ρ'-DDT respectively.The results showed that 14 samples of Ginseng Radix 70 and 16 samples of Sennae Folium 80 were found to have pesticide residues. The other 60 samples including Cinnamonomi Cortex, Poria and Glycyrrhizae Radix were not found with residues of the nine pesticides mentioned above.
