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 ( summation operator(8)PBDEs) and BDE-209 in sediments ranged from 0.27 to 76.54ng/g with an average of 16.31ng/g and from 0.10 to 70.11ng/g with an average of 14.94ng/g, respectively. Concentrations of summation operator(8)PBDEs in porewater ranged from 2.5 to 34.1ng/L, with a mean value of 15.3ng/L. In this study, the partition coefficients (log K(oc)(')) of PBDE congeners (without -209) were significantly correlated with their octanol-water partition coefficients (log K(OW)) (r(2)=0.74, P<0.01). summation operator(8)PBDE concentrations ranged from 0.33 to 1.26ng/g (lipid weight) in marine organisms, and PBDE congener patterns were significantly different between fish and clam, crab.
对厦门近海 12 个站位的表层沉积物和孔隙水以及污染严重的远垵港湾生物体进行了采样和 8 种多溴二苯醚（PBDEs）同系物（-28、-47、-99、-100、-153、-154、-183 和 -209）分析。沉积物中 8 种 PBDEs（∑8PBDEs）和 BDE-209 的总浓度范围为 0.27-76.54ng/g，平均值为 16.31ng/g；0.10-70.11ng/g，平均值为 14.94ng/g。孔隙水中∑8PBDEs 的浓度范围为 2.5-34.1ng/L，平均值为 15.3ng/L。在本研究中，PBDE 同系物（不包括 -209）的分配系数（log K(oc)(')）与辛醇-水分配系数（log K(OW)）呈显著正相关（r(2)=0.74，P<0.01）。海洋生物体中∑8PBDEs 的浓度范围为 0.33-1.26ng/g（脂重），鱼类和贝类、蟹类中 PBDE 同系物的模式明显不同。
