夏季海河与渤海湾中壬基酚和辛基酚污染的状况

The pollution state of nonylphenol and octylphenol in Haihe River and Bohai Bay in summer.

对夏季海河与渤海湾表层水中溶解态的壬基酚(NP)和辛基酚(OP)的污染状况进行了调查.结果表明,海河中NP和OP的浓度分别为160～429ng/L和18～56ng/L;渤海湾中NP和OP的浓度分别为33～132ng/L和n.d.～14ng/L.污水排放是海河中NP和OP的重要来源.渤海湾中NP和OP的浓度要远远低于海河,但是海水稀释不是造成其浓度降低的唯一原因.研究还发现该地区NP和OP与CODMn和TP具有显著的正相关.与珠江三角洲相比,该地区NP和OP污染情况较为严重,与国外其他类似区域相比则处于中等或较低水平.

The pollution state of soluble nonylphenol （NP） and octylphenol （OP） in the summer surface water of Haihe River and Bohai Bay was investigated. NP and OP concentrations in Haihe River were 160-429ng/L and 18-56ng/L respectively, and in Bohai Bay were 33-132ng/L and n.d.-14ng/L respectively. Wastewater discharged was the important source of NP and OP in Haihe River. In the Bohai Bay, NP and OP concentrations were far lower than those in Haihe River; but the dilution of sea water was not the only cause of its concentration lowering. NP and OP possessed remarked positive correlation with CODMn and TP in this area. The pollution state of NP and OP in this area was serious relatively, compared with Peal River delta; and medium or lower level compared with the similar areas abroad.
