The chemical industrial zone located along the Xiaoqing River wetlands adjacent to Bohai Sea is one of the largest production bases for brominated flame retardants in China. Herein, high levels of bisphenol-A, tetrabromobisphenol-A (TBBPA), tribromobisphenol-A, dibromobisphenol-A, and monobromobisphenol-A were detected in sediment, soil, and water samples of this zone in the range of below method detection limit (<MDL)-5.45 × 10 ng/kg dw, <MDL-8.37 × 10 ng/kg dw, and <MDL-5.59 × 10 ng/L, respectively. They were mainly buried in sediments as their highest levels in sediment samples. The small concentration fluctuation between water samples retrieved in the upstream and downstream zones is likely attributed to seawater backflow. The nearby chemical factories were point pollution sources and the less brominated analogs are largely from debromination of TBBPA. High pollution levels and the ecological risks of these pollutants along the Xiaoqing estuary to Bohai Sea need to be further assessed in future studies.
沿小清河流域湿地毗邻渤海的化工园区是中国最大的溴系阻燃剂生产基地之一。在该地区的沉积物、土壤和水样中检测到了高水平的双酚 A、四溴双酚 A（TBBPA）、三溴双酚 A、二溴双酚 A 和一溴双酚 A，其浓度范围分别为低于方法检测限（
