摘要(Abstract)：

多溴联苯醚(PBDEs)作为一种新型的持久性有机污染物,在海洋环境中广泛存在,研究PBDEs在不同介质中的赋存状态对于理解其环境行为及归趋具有重要的意义。通过采集不同区域沉积物及生物样品,考察了PBDEs在环渤海近岸海域表层沉积物及底栖生物中的含量及空间分布特征、污染模式及生物-沉积物富集因子。结果表明,环渤海沿岸表层沉积物中PBDEs总量(Σ10PBDEs)的浓度范围在0.446~26.8 ng·g-1(干重,dw)之间,中值为1.02 ng·g-1(dw),底栖生物中PBDEs(Σ9PBDEs)的浓度范围为0.053~9.90 ng·g-1(dw),中值为1.25 ng·g-1dw;沉积物中BDE-209为最主要的单体,平均丰度达到90.5%,生物体中主要以低溴代BDEs为主,其中单体BDE-47的含量最高,平均丰度范围为43.2%~49.7%;沉积物和生物中PBDEs的含量在空间上存在显著的差异,其中莱州湾和锦州附近区域的结果明显高于其他区域;5种不同的底栖生物对PBDEs均表现出一定的生物富集性,其中∑9PBDEs的BSAF值按从大到小的顺序为菲律宾蛤仔(0.43~4.06,mean=1.19)>紫贻贝(0.34~2.86,1.03)>四角蛤蜊(0.17~1.95,0.82)>麻蛤(0.13~2.33,0.61)>牡蛎(0.09~1.20,0.52)。辛醇水分配系数(log KOW)与不同物种BSAF值的相关性分析结果表明,除BDE-17单体外,其他单体的BSAF值表现出随log KOW的升高而下降的趋势。
