Abstract

Polybrominated diphenyl ethers (PBDEs) were determined in 36 fish samples near a deca- brominated diphenyl ether (deca-BDE) production facility in Weifang City, Shandong Province, China. The concentrations of PBDEs in fish muscle and liver samples were from 45.8 to 560 ng g−1 lipid weight (lw) and 327 to 2120 ng g−1, lw, respectively. The highest concentration of PBDEs was found in carp with a mean value of 1370 ng g−1, lw, followed by crucian with a mean of 1030 ng g−1, lw, and grass carp with a mean of 681 ng g−1, lw. Relatively constant congener patterns were observed among the fish species. BDE-47 was the most predominant congener with contributions of 50.1% to 89.7% to the total PBDE concentrations. Different BDE-99/BDE-100 ratios were observed, indicating that the PBDE pattern is species-dependent.
