摘　　要：自西安市地表水体中采集了表层沉积物样品，采用高效液相色谱紫外法检测了样品中的多溴联苯醚（PBDEs），以研究该环境中多澳联苯醚的含量、分布、来源和在环境中的迁移。研究结果表明，团结水库中PBDEs的含量较高，最高为218.42ng／g，其他水体环境中PBDEs含量较低；PBDEs主要来自西安市工业和生活污水的排放，渭河是这些污水的“汇”，而这些污水则是渭河中PBDEs的“源”。Surficial sediment samples of the water were collected from xi an and analyzed by high performance liquid chromatograph for assessment of distribution,.source and transport of PBDEs in the aquatic environment. The results showed that PBDEs of the Reservoir Unity was more than of that, the highest concentrations was 218.42ng/g, PBDEs in the water were originated from sewagc, Weihe River was the sink of sewage, sewage was the ~urces of PBDEs of Weihe River.
