| 摘 要： | 为分析青岛胶州湾及其邻近河流中的壬基酚（NP）及其短链氧乙烯醚母体化合物、壬基酚单氧乙烯醚（NP1EO）和壬基酚二氧乙烯醚（NP2EO）的污染状况和分布特征，在研究区域内设置了17个站位分别采集了海水和沉积物样品，样品经萃取、浓缩、净化后采用气质联用仪测定各污染物的浓度。胶州湾水体中的NP、NP1EO和NP2EO的浓度分别为20．2-268．7、11．2-200．4和4．8-32．5ng／L。胶州湾沉积物中上述3种污染物的浓度分别为3．6-299．3、3．8-25．2和4．9-103．2ng／g。胶州湾邻近河流中的污染物浓度远远高于湾内，其中墨水河的污染最严重，水体和沉积物中NP的浓度分别达到28656ng／L和31704ng／g。与世界其他海湾NP等污染物的浓度相比，胶州湾属于严重污染地区之一，已经超出了其生物效应临界浓度。研究区域内50％的站位中NP浓度已经超过导致扇贝苗死亡的临界浓度，10％的站位已经超过引起雄性鱼类雌性化的临界浓度。

| Abstract: | Pollution and distribution of nonylphenol (NP), nonylphenol monoethoxylate (NPIEO) and nonylphenol diethoxylate (NPZEO) in Jiaozhou Bay and its adjacent rivers were studied. Water and sediment samples were collected from 17 stations in the study area. The samples were extracted, concentrated and purified. Each pollutant species was quantified with GC-MS. The concentrations of NP, NPIEO, and NPZEO in surface waters of Jiaozhou Bay ranged 20.2-268.7, 11.2-200.4 and 4.8-232.5 ng/L, and in the sediments 3.6-299.3, 3.8-25.2 and 4.9-103.2 ng/g, respectively. The contamination in the adjacent rivers was much more serious than inside the bay. Moshui River is most seriously polluted reaching nonylphenol concentrations of 28656 ng/L and 31704 ng/g in water and sediment, respectively. Compared with other bays in the world, Jiaozhou Bay is one of the most polluted areas, with the concentrations exceeding the threshold biological effect level, building potential risks on local organisms. |
