| 摘 要： | 采用毛细管GC ECD法测定大连湾、辽东湾表层沉积物及表层、微表层海水中 16种有机氯农药 (OCP16 )的含量。结果表明 ,辽东湾海区表层海水OCPs平均质量浓度为 4 1.94ng/L ,显著高于大连湾海区 4 .5 2ng/L的平均值 ,但 2个湾OCPs质量浓度均未超出渔业水质标准。辽东湾表层沉积物OCPs平均质量分数为 10 .15ng/g ,也明显高于大连湾表层沉积物 6.17ng/ g的平均水平。表明辽东湾有机氯农药污染程度较大连湾重。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 ,平均富集系数为 5 .1～ 15 .4。

| Abstract: | The contents of 16 kinds of organochlorine pesticides (OCP 16 ) in the sediments, surface and microlayer seawater in Dalian Bay and Liaodong Bay (Liaoning Province) were determined by capillary GC ECD. The results show that the average concentration of OCPs in the surface seawater is 41.94 ng/L in Liaodong Bay, significantly higher than 4.52 ng/L in Dlian Bay, but both do not overpass the water quality standard for fisheries of China. The average content of OCPs in the sediments is 10.15 ng/g in Liaodong Bay, significantly higher than 6.17 ng/g in Dalian Bay. But the pollution level in Liaodong Bay is relatively higher than that in Dalian Bay. The OCPs concentration in microlayer seawater is significantly higher than that in the surface seawater of Dalian Bay, which reveals that the surface water has a strong accumulation of OCPs with the average accumulating coefficient of 5.1-15.4. |
