利用气质联用仪（GC-NCI-MS）对台州地区表层土壤和灰尘样品中PBDEs的含量进行检测，并分析了PBDE同系物的分布模式，比较了不同功能区域PBDEs的污染水平、分布特征及来源分析。结果显示：PBDEs在土壤和灰尘中的含量分别为227~8447 ng·g-1（均值2090 ng·g-1）和313~29787 ng·g-1（均值8723 ng·g-1）；不同功能区域土壤和灰尘样品中均显示BDE-209是最主要的同系物，且土壤中BDE-209所占的比例高于灰尘；随着与污染源的距离增加，PBDEs总含量呈逐渐下降趋势。土壤和灰尘中特定BDE含量之间无显著相关，土壤TOC与所有PBDE同系物之间极显著相关（P<0.01），表明土壤TOC对PBDEs污染物在土壤中的分布、迁移转化等有重要的影响。主成分分析和聚类分析进一步表明，十溴工业品可能是当地PBDEs污染的主要来源之一。

Polybrominated diphenyl ethers(PBDEs)are flame-retardant chemicals commonly used in electronics. Therefore, e-waste recy-cling activities have caused PBDE pollution in the surrounding environment. In this study, PBDEs in surface soil and outdoor dust samples collected from e-waste recycling areas in Taizhou were measured by GC-NCI-MS. The content of PBDEs was in the range of 227~8447 ng· g-1(mean value 2090 ng·g-1)and 313~29 787 ng·g-1(mean value 8723 ng·g-1)in soils and dusts, respectively. Of soil and dust samples collected from different functional regions, BDE-209 was the dominant congener, which was much higher in soils than in dusts. The total PBDEs content tended to decrease with the distance from the pollution sources. No apparent correlation between PBDEs content in soil and dust was found, but PBDE congeners was significantly correlated with soil TOC, indicating the significant influence of TOC on PBDEs dis-tribution, migration and transformation. Principal component and cluster analysis confirmed that the industrial products containing deca-BDE might be the main source of PBDEs in the region.
