| 摘 要： | 建立了固相微萃取(SPME)技术结合气相色谱-电子捕获(GC—ECD)检测方法，对大连近海养殖区内海水中的痕量12种有机氯农药进行检测，以便对该水域中海产品的食品安全性进行评估。该法具有较好的线性(相关系数为0．98～0．99)，检出限达0．2～7ng／L，定量下限为0．66～23ng／L，重复测定的相对标准偏差小于10％(n=3)，回收率为68％～133％。对影响SPME的参数和海水中存在的基质干扰进行探讨。

| Abstract: | A method for the determination of12trace-level organic chlorinated pesticides in the seawater of Dalian off shore culturing area by SPME-GC-ECD was developed,and the safety for the seafoods in this area was also evaluated.The operation parameters of SPME were optimized,and the matrixeffects in the sea-water were discussed.The linearity in the detecting range is good(0.98-0.99)with the detection limits of0.2-7ng/L,and the quantification limits of0.66-23ng/L.The RSDs were lower than10%,and the re-coveries were68%-133%.It is proved to be simple,fast and accurate for analyzing the organic chlorinated pesticides in seawater. |
