【摘要】 分别自贵州红枫湖7个采样点采集2个水文期的表层沉积物样品,以研究贵州红枫湖中PBDEs的含量、分布特征及来源。研究结果表明,贵州红枫湖中∑PBDEs为ND～9.04 ng/g(dw),与已有的文献报道相比,贵州红枫湖中PBDEs的污染还处于一个较低的水平。在所有被分析的样品中,BDE47为最主要的同系物,大气沉降是红枫湖中PBDEs的主要来源。更多还原

【Abstract】 Surface Sediment samples were collected from seven sites in the Hongfeng Lake of Guizhou Province during two hydrological periods with a view to studying the content,distribution features and source of polybrominated diphenyl ethers(PBDEs).The results indicated that the∑PBDEs in the Hongfeng Lake was ND～9.04 ng/g(dw) which,compared with the data reported in the literature,was still in a low level.The sample analysis showed that BDE47 was the dominant congener and that atmospheric deposition was the main source of PBDEs.更多还原
