| Abstract: |
| Polybrominated diphenyl ethers(PBDEs) are flame-retardant chemicals commonly used in electronics. Therefore, e-waste recycling 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 distribution, 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. |
