Surface soil samples were collected from Suzhou, Wuxi and Nantong in the Yangtze River Delta (YRD), China. Eight BDE congeners (BDE-28, 47, 99, 100, 153, 154, 183 and 209) were measured to determine the levels and compositional profiles in the samples. The concentrations of Σ7PBDEs and BDE-209 ranged from 0.04 to 2.23 μg/kg dw and 1.48 to 41.7 μg/kg dw in the samples, respectively. BDE-209 was the predominant congener (contributing to 69.2 %-99.8 % of Σ8PBDEs) in all samples. It was found that small towns and rural economic development zones in this region had also become sources of polybrominated diphenyl ethers pollutants to surrounding areas. Investigation of the pattern of BDE congener profiles showed that deca- and octa- technical formulations as emission sources were identified in the samples collected from the YRD.
表层土壤样本采自中国长江三角洲地区的苏州、无锡和南通。测定了8种溴代二苯醚同系物（BDE-28、47、99、100、153、154、183和209），以确定样本中的含量水平和组成分布。样本中Σ7多溴联苯醚和BDE-209的浓度分别为0.04至2.23 μg/kg干重和1.48至41.7 μg/kg干重。BDE-209是所有样本中的主要同系物（占Σ8多溴联苯醚的69.2%-99.8%）。研究发现，该地区的小城镇和农村经济开发区也已成为多溴二苯醚污染物向周边地区扩散的源头。对溴代二苯醚同系物分布模式的调查表明，在采自长江三角洲地区的样本中，已识别出十溴和八溴商用配方产品为排放源。
