摘要
分析了渤海表层沉积物中壬基酚和双酚A的分布特征。结果表明,壬基酚的含量介于(3.16～13.6)×10-9(dw),高值区出现在渤海湾近岸,其次为辽东半岛近岸和莱州湾近岸,其它海区的含量均低于7.50×10-9(dw),且变化幅度较小。渤海沉积物中的双酚A含量普遍较低,介于(ND～1.44)×10-9(dw),高值区出现在辽东湾近岸。壬基酚和双酚A的含量分布受到陆源输入、环流体系及沉积环境等因素的共同影响。本文还讨论了渤海中壬基酚和双酚A的潜在生态风险。
The spatial distribution of NP and BPA in surface sediment in Bohai Sea was investigated in summer.The result showed that the concentrations of NP in surface sediment ranged（3.16~13.63）×10-9（dw）.The high concentrations were in the coastal area of Bohai Bay,Liaodong Peninsula and Laizhou Bay and concentrations in the other stations were below 7.50×10-9（dw）.The contents of BPA were relatively low,ranged from ND to 1.44×10-9（dw）,and the highest concentration was in the coastal area of Liaodong Bay.The distribution pattern of NP and BPA was influenced by the land sources,current circulation system and depositional environment.The potential ecological risks of NP and BPA were also discussed.
