Nineteen surface sediment samples collected from Baiyangdian Lake and its in flowing river (Fuhe River) in North China were analyzed for polybrominated diphenyl ethers (PBDEs) and decabromodiphenylethane (DBDPE) The concentrations of PBDEs and DBDPE in sediments ranged from 5 5 to 300 7 ng/g dry weight (dw) and 1 1 to 68 2 ng/g dw respectively Their levels in sediments in Fuhe River were significantly higher than those in Baiyandian Lake Compared to data from other regions, the PBDE levels in surface sediments from Baiyangdian Lake and Fuhe River were in the medium to lower range Among the PBDE congeners BDE209 was predominant with contributions to the total PBDEs ranging from 79 4% to 97 3% in sediment samples For the lowly brominated congenors (tri- to hepta-BDE) BDE47 and BDE99 were the most abundant, which contributed 52 1% and 44 1% to the sum of tri- to hepta-BDEs in the sediments from Baiyangdian Lake and Fuhe River respectively The compositional patterns of PBDEs in Baiyangdian Lake sediments indicated that technical deca BDE mixture was the major pollutant sources with a minor contribution of penta BDE mixture The present study suggested that the Importance of Fuhe River as a possibly potential sources of PBDEs contamination in Baiyangdian Lake
