禽畜產品中加保利、百滅寧及協力精檢測方法之開發

Method Development for Determination of Carbaryl, Permethrin and Piperonyl Butoxide in Livestock and Poultry Products

指導教授 : 葉華光

摘要


畜舍環境衛生及家禽動物寄生蟲主要使用加保利(CRB)和百滅寧(PER)殺蟲劑來控制及預防,在畜舍清潔及消毒過程中,所飼養的動物皆可能長期暴露在這些物質中。CRB、PER及協力精(PBO)在環境荷爾蒙清單中被列為疑似環境荷爾蒙物質,這類物質國內外皆訂有最高殘留容許量,但是無分析方法檢測禽畜產品中的殘留。為防範禽畜產品中殘留問題,必需建立準確、快速及有效率的分析方法進行監測,以維護消費者食用安全。本研究以乙腈進行禽畜產品中CRB、PER及PBO的萃取,萃取液經一級二級胺(Primary secondary amine, PSA)粉末吸附劑淨化處理後,分別以高效能液相層析儀分析CRB,氣相層析質譜儀分析PER及PBO。本方法於CRB標準檢量線之線性範圍在0 ~ 500 ng/mL 時R2 為0.9999,PER之線性範圍在0 ~ 60 ng/mL 時R2 為0.9976,PBO之線性範圍在0 ~ 70 ng/mL 時R2 為0.9984。CRB、PER及PBO偵測極限分別為5.0、3.5及3.2 ng/mL,定量極限值分別為16.6、11.7及10.6 ng/mL。以標準品添加三種濃度(0.2、1.0.與2.0 μg/mL)在禽畜測試樣品中,得分析之回收率範圍為71.7 ~ 112.0 %。於同一天內重複測試此三種濃度樣品之相對標準差為1.8 ~ 9.3 %,於不同天重複測試之相對標準差為1.6 ~ 13.3 %。在真實樣品檢測中未檢測出CRB、PER及PBO藥物殘留存在。整體而言,本方法具有快速、良好的重複性、再現性及準確度,可成功的應用在禽畜產品中CRB、PER及PBO的殘留分析。

To control and prevent parasites infect poultry and livestock in barn with used carbaryl and permethrin. The domestic animals will exposure long-time in this materials because of cleaning and disinfect. carbaryl (CRB), permethrin (PER) and piperonyl butoxide (PBO) were belong to endocrine disrupters substance, therefor, these materials were have maximum residue limits internationally, but there are no analytical method to detect the residues of CRB,PER and PBO in livestock and poultry products. In order to prevent the problem of CRB, PER and PBO residues in livestock and poultry products, a precise, accurate and rapid analytical method for examining CRB, PER and PBO in livestock and poultry products must be developed. Samples were extracted with acetonitrile; the following cleanup was carried out on a primary secondary amine absorbents. For CRB was detected by high performance liquid chromatography. For PER and PBO was detected by Gas Chromatography-Mass Spectrum. The liner concentration range of the calibration curves of CRB, PER and PBO were 0-500 ng/mL (R2 = 0.9999), 0-60 (R2 = 0.9976) and 0-70 ng/mL (R2 = 0.9984), respectively. The limit of detection (LOD) of CRB, PER and PBO were 5.0, 3.5 and 3.2 ng/mL, respectively and limit of quantification (LOQ) were 16.6, 11.7 and 10.6 ng/mL, respectively. Recoveries of spiking experiments at three different concentration levels of CRB, PER and PBO, 0.2, 1.0 and 2.0 ng/mL in livestock and poultry products samples were 72-112%. The corresponding inter-day and intra-day precision expressed at relative standard deviations (RSD %) were 1.8-9.3% and 1.6-13.3%, respectively. No CRB, PER and PBO residues were detected in the real samples. Overall, the developed method exhibited with rapid analysis, good sensitivity, reproducibility, repeatability, and accuracy for the analysis of CRB, PER and PBO residue in livestock and poultry products.
