چکیده انگلیسی
Surface sediments and porewater from 12 sites within Xiamen offshore areas and organisms from a heavily contaminated site Yuandang Lagoon were sampled and analyzed for eight polybrominated diphenyl ethers (PBDEs) congeners (-28, -47, -99, -100, -153, -154, -183 and -209). The total concentrations of eight PBDEs (â8PBDEs) and BDE-209 in sediments ranged from 0.27 to 76.54Â ng/g with an average of 16.31Â ng/g and from 0.10 to 70.11Â ng/g with an average of 14.94Â ng/g, respectively. Concentrations of â8PBDEs in porewater ranged from 2.5 to 34.1Â ng/L, with a mean value of 15.3Â ng/L. In this study, the partition coefficients (log Kocâ²) of PBDE congeners (without -209) were significantly correlated with their octanol-water partition coefficients (log KOW) (r2Â =Â 0.74, PÂ <Â 0.01). â8PBDE concentrations ranged from 0.33 to 1.26Â ng/g (lipid weight) in marine organisms, and PBDE congener patterns were significantly different between fish and clam, crab.
