中文摘要 | 三亞蟎20%乳劑噴施於柑桔及梨園,並於施藥前、後分別收集七位農民之尿液,分析三亞蟎及其代謝產物BTS-27919,BTS-27271,2,4-dimethylaniline之含量。取5mL尿液樣品以SPE-C18 (500mg,3mL) 淨化,於不同溶劑分段收集三亞蟎及其代謝產物,並以氣液層析儀附質吉普檢測器偵測。本方法回收率三亞蟎為75.7 ± 4.2%、BTS-27271為81.3 ± 2.4%、BTS-27919為87.7 ± 3.7%、2,4-dimethylaniline為83.3 ± 1.8%。而七位農民尿液中均未檢測出三亞蟎及其代謝產物之殘量。 |
英文摘要 | Urine samples were collected from seven farmers before and after applying 20% amitraz EC to pear and citrus fields. Amitraz and its metabolites including BTS-27919, BTS-27271, and 2,4-dimethylaniline were eluted with n-hexane, dichloromethane and methanol in sequence from SPE-C18 cartridge by loading 5 mL of urine before GC-MSD determination. The mean recoveries of amitraz, BTS-27919, BTS-27271 and 2,4-dimethylaniline were 75.7 ±4.2 , 81.3 ±2.4 , 87.7 ±3.7 and 83.3 ±1.8%, respectively. Neither amitraz nor metabolites were detected in any of the seven farmers, urine samples. |
