| Abstract: |
| Sixty sediment samples were collected from the main Songhua River in three years. Twelve polybrominated diphenyl ether (PBDE) congeners (BDE7,8, 7,6, 9,0, 3,4, 8,3, and BDE-209) were detected to state the pollution situation. The results showed that the total concentration of total PBDEs ranges from 0.424 to 23.0 ng/g dry weight, with the mean of 3.02 ng/g, and the total PBDEs concentration is at relative low level compared with those worldwide. The congener profile showed that BDE-209 is the dominant congener that accounts for more than 80.1％ of total PBDEs in sediments, followed by BDE-47 and BDE-99. These profiles are consistent with a high consumption of Deca-BDEs for the brominated flame retardant market in China. The results of spatial and seasonal observations indicated that local sources, temperature variation, and hydrologic conditions are significant factors on PBDEs concentrations. Hazard quotients suggested that PBDEs pose no potential risk to benthic organisms in detected area at present. |
