摘要

对白洋淀入湖河流(府河)水体中的典型持久性有机污染物——多溴联苯醚(PBDEs)的浓度分布规律进行了综合调查和分析。结果表明:白洋淀入湖河流中总PBDEs质量浓度为38.7～216.3ng/L;以污水处理厂为分界点,各PBDEs在污水处理厂上下游水体中所占比例不同,上游段主要污染物为十溴代的BDE-209,其次为五溴代的BDE-100;经流污水处理厂后,下游段水体中未检出BDE-209,主要污染物变为四溴代的BDE-47,其次为五溴代的BDE-99、BDE-100。与污水处理厂上游段相比,下游段中一溴代的BDE-3、二溴代的BDE-10和BDE-33/28以及BDE-99、BDE-100、BDE-209均有不同程度的下降,而BDE-47略有上升。研究结果可为了解白洋淀及其上游流域PBDEs的浓度分布现状及进一步开展白洋淀生态风险评估提供数据支持。
        A comprehensive investigation and analysis of concentration distribution patterns of typical persistent organic pollutants-PBDEs in the influent waters(Fuhe Rive)of Baiyangdian Lake were carried out.The results showed that the total mass concentration of PBDEs ranged from 38.7to 216.3ng/L.The sewage treatment plant as the demarcation point,different PBDEs had different proportions in the upstream section and downstream section of sewage treatment plant,and the main pollutant in the upstream section was decabromodiphenyl ether(BDE-209),followed by pentabromodiphenyl ether(BDE-100).After the sewage treatment plant,BDE-209 was not detected in the downstream section,and the main pollutant changed to tetrabromodiphenyl ether(BDE-47),the following PBDEs pentabromodiphenyl ether(BDE-99),BDE-100.Monobromodiphenyl ether(BDE-3),dibromodiphenyl ether(BDE-10 and BDE-33/28),BDE-99,BDE-100 and BDE-209 in the downstream section all decreased in different degrees compared with the upstream section.However,BDE-47 increased slightly.The research results could be used to understand the current situation of PBDEs concentration distribution in Baiyangdian Lake and its upper catchment,and it also provided data support for further ecological risk assessment of Baiyangdian Lake.
