Abstract

Organism (fish, shrimp, crab and cuttlefish) samples were collected in the sea area of Daya Bay in September, 2003 to analyze the concentration of polybrominated diphenyl ethers (PBDEs) and lipid content, and the values of isotope δ15N and δ13C. The total average concentrations of PBDEs in fish, shrimp, crab and cuttlefish were 5.43 ± 3.97, 1.18 ± 0.67, 3.37 ± 2.33 and 5.66 ng/g lipid weight respectively. PBDEs bioaccumulation ratio was higher relatively in carnivorous fishes than that in planktivorous fishes. BDE47 was the predominant component, occupying 30% of total PBDEs, and was detected in all samples. In organism, positive relationships existed between PBDEs concentration, lipid content and δ15N value. The influence of lipid content on organism acuminating PBDEs was much greater compared with the influence of trophic level of organism.
