KEY WORDS: OH-PBDEs; contents; Taihu Lake aquatic; pollution

ABSTRACT: Objective To investigate the contamination of OH-PBDEs in aquatic products of Taihu Lake. Methods A method for the determination of OH-PBDEs in aquatic products was established firstly, and then the concentration of OH-PBDEs in 17 kinds of aquatic products and 3 species of aquatic vegetables in the Taihu lake basin was measured. Results Fish living in the middle and lower layers and mud had higher levels of OH-PBDEs(ND~3.3839 ng/g(dw))than the upper's(ND~l.6169 ng/g(dw)); there was higher level of OH-PBDEs in fish than plant. The concentration of OH-PBDEs in the grass carp, bream, bighead carp and siniperca chuatsi was higher than the other types of fish, and most OH-PBDEs was contained in the intima of the visceral. Conclusion The contamination of OH-PBDEs in aquatic products of Taihu Lake was surveyed systematically.
