本文首次全面调查了岩心沉积物样品中多溴二苯醚 (PBDE) 的同系物分布（12 种同系物）（ 99 > 100 > 154，与世界范围内的分布模式相似。虽然在所有样品中均发现了四溴二苯醚 BDE 47，其次是六溴二苯醚 BDE-154，但它们不一定是主要同系物。未记录到 PBDE 水平的统一时间趋势可能是由于湿地的特定水文特征和/或这些化合物的点源（未经处理的城市废水和当地工业、垃圾场的电子废物等）的非同源输入。由于多溴联苯醚易于在野生动物和人类食物网的各个部分中积累，因此应高度重视生物组织的评估（C）2007 Elsevier Ltd。保留所有权利。
The paper presents the first comprehensive survey of congener profiles (12 congeners) of polybrominated diphenyl ethers (PBDEs) in core sediment samples ( 99 > 100 > 154, similar to the distribution pattern worldwide. Although tetrabromodiphenyl ether BDE 47 was found in all samples followed by hexabromodiphenyl ether BDE-154, they were not necessarily the dominant congeners. No uniform temporal trend on PBDE levels was recorded probably due to particular hydrological characteristics of the wetland and/on non-homologous inputs from point sources (untreated municipal wastewater and local industries, electronic wastes from the dump sites, etc.) of these compounds. Because of the propensity of PBDEs to accumulate in various compartments of wildlife and human food webs, evaluation of biological tissues should be undertaken as a high priority.
