| 中文摘要 |
| 在夏季对海河与渤海湾表层水中溶解态的多氯联苯（PCBs）和有机氯农药（OCPs）的污染状况进行了调查．结果表明，海河和渤海湾表层水中PCBs、六六六和滴滴涕的含量分别为0.06～3.11 μg/L、0.05～1.07 μg/L和0.01～0.15 μg/L．海河干流流域内的工业废水排放等陆源输入可能是渤海湾中PCBs和OCPs的重要来源．研究表明该地区PCBs与水中的DOC（dissolved organic carbon）具有一定的正相关．与国内外类似水体相比，海河中PCBs和OCPs污染情况较为严重，而渤海湾则处于中等水平． |
| 英文摘要 |
| Polychlorinated biphenyls (PCBs), hexachlorocyclohexanes (HCHs) and dichlorodiphenyl-trichloroethanes (DDTs) were analyzed in the surface water of Haihe River and Bohai Bay, in north of China. Concentrations of PCBs, HCHs and DDTs were 0.31～3.11 μg/L, 0.30～1.07 μg/L and 0.02～0.15 μg/L in river, and in sea were 0.06～0.70 μg/L, 0.05～0.75 μg/L and 0.01～0.11 μg/L respectively. Mostly, the PCBs, HCHs and DDTs in the Bohai Bay are from terrestrial input by Haihe River. PCBs and organic chlorinated pesticides (OCPs) are positively correlated with DOC (dissolved organic carbon). The levels of PCBs and OCPs in Haihe River in this study are quite higher than the similar surface waters in China, while the levels in Bohai Bay are quite consistent with similar waters abroad. |
