研究采用固相萃取(SPE)-气相色谱-质谱法(GC-MS)对2012年5月份渤海南部表层海水中的辛基酚(OP)和双酚A(BPA)的污染状况进行了调查。结果表明,渤海南部56个站位表层海水中OP均有检出,浓度范围<1.50~20.1 ng/L,平均浓度4.17 ng/L,BPA均有检出,浓度范围<1.50~275 ng/L,平均浓度34.8 ng/L。OP高浓度分布在漏油事故区Y系列和黄河口南部、莱州湾西部湾口以及SL20站位,且莱州湾湾口普遍高于湾内;BPA总体分布莱州湾沿岸站位浓度普遍较高。渤海南部表层海水中OP污染较胶州湾等水体严重,BPA浓度部分站位浓度已达到泥螺胚胎生成的4周10%效应浓度(EC10)。由此可知,渤海南部已经受到OP和BPA不同程度的污染,有可能对生物带来一定的生态风险。
The concentrations of octylphenol (OP) and bisphenol A (BPA) in the surface seawater of the southern Bohai Sea in May 2012 were investigated by solid phase extraction (SPE) and gas chromatography-mass spectrometry (GC-MS) The results showed that OP was detected in surface seawater of 56 stations in the southern Bohai Sea with concentrations ranging from 1.50 to 20.1 ng / L and an average concentration of 4.17 ng / L, with BPA ranging from 1.50 to 275 ng / L , The average concentration of 34.8 ng / L. The high concentration of OP distributes in the oil spill zone Y series, the southern part of the Yellow River mouth, the western bayou of Laizhou Bay and the SL20 station, and the bay mouth of Laizhou Bay is generally higher than that of the bay; BPA generally has a higher concentration of stations along Laizhou Bay. The OP pollution in surface seawater of southern Bohai Sea was more serious than that of Jiaozhou Bay. The concentration of BPA in some stations had reached 10% of the 4-week 10% EC10 concentration. It can be seen that the southern Bohai Sea has been polluted to varying degrees by OP and BPA, which may bring some ecological risks to the organisms.
