| 摘 要： | 采用毛细管GC-ECD法测定了大连湾海域表层沉积物及表层、微表层海水中16种有机氯农药(OCP16)的含量。结果表明，毛细管GC-ECD测定OCPs回收率高、响应因子变异系数小、检出限低，适合于海洋环境样品中OCPs测定。在大连湾海域沉积物和水体中对OCPs均有检出，但污染水平相对较低。表层海水中OCPs平均含量为4.52 ng/L，表层沉积物中OCPs平均含量为6.17 ng/g。大连湾各站位微表层海水OCPs含量显著高于表层水，显示微表层海水对OCPs有较强的富集作用，平均富集系数在5.1～15.4之间。

| Abstract: | The contents of sixteen organochlorine pesticides (OCP16) in surface sediments of seawater, surface seawater and microlayer seawater, respectively, in Dalian Bay were determined by capillary GC ECD method. The results show that recovery rate of OCPs determination by capillary GC ECD is high, coefficient of variation of response factor small and detection limit low, and the method is fit for the determination of OCPs in marine environment samples. OCPs in both sediment and seawater in Dalian Bay are detected, but pollution level is relatively low. The average concentration of OCPs in surface seawater is 4.52 ng/L, and OCPs in surface seawater sediment is 6.17 ng/g. The contents of OCPs in microlayer seawater are much higher than those in surface seawater, which indicates that there is strong enrichment of OCPs into microlayer seawater and the average enrichment factor is among 5.1~15.4. |
