The levels of polybrominated diphenyl ethers (PBDEs) and indicator polychlorinated biphenyls (PCBs) were determined in marine fish from four areas of China (South China Sea, Bohai Sea, East China Sea, and Yellow Sea) using GC/NCI-MS and GC/ITMS, respectively. Total concentrations of eight PBDEs (BDE-28, 47, 99, 100, 153, 154, 183 and 209) in all samples ranged from 0.3ngg(-1)ww (wet weight) to 700 ng g(-1)ww, with median and mean values of 85 ng g(-1)ww and 200 ng g(-1)ww, respectively. BDE-209 and BDE-47 were the major congeners in all samples, contributing 54% and 19% to the total concentration, respectively. The sum of seven indicator PCB levels (CB-28, 52, 101, 118, 138, 153, and 180) ranged from 0.3 ng g(-1)ww to 3.1 μg g(-1)ww, with median and mean values of 6.4 ng g(-1)ww and 398 ng g(-1)ww, respectively. High contributions of CB-138 (32%) and CB-153 (25%) were found in all samples. In general, pollutants measured in this study were at high levels when compared with previous studies from other regions in the world. The relative abundance of BDE-209 may suggest that deca-BDE sources existed in studied area. And principal component analysis (PCA) showed that there were other PBDE sources in Yellow Sea. The pattern and PCA showed that PCB pollutions came from similar sources in the studied areas. In addition, concentrations of ∑(7)PBDEs (u/209) were strongly correlated with those of ∑(7)PCBs in all fish (r=0.907, n=44).
采用 GC/NCI-MS 和 GC/ITMS 分别测定了中国南海、渤海、东海和黄海四个海域的鱼类中多溴二苯醚（PBDEs）和指示性多氯联苯（PCBs）的水平。所有样品中八种 PBDEs（BDE-28、47、99、100、153、154、183 和 209）的总浓度范围为 0.3ngg(-1)ww（湿重）至 700ng g(-1)ww，中位数和平均值分别为 85ng g(-1)ww 和 200ng g(-1)ww。所有样品中 BDE-209 和 BDE-47 是主要同系物，分别占总浓度的 54%和 19%。七种指示性 PCB 水平（CB-28、52、101、118、138、153 和 180）的总和范围为 0.3ng g(-1)ww 至 3.1μg g(-1)ww，中位数和平均值分别为 6.4ng g(-1)ww 和 398ng g(-1)ww。所有样品中 CB-138（32%）和 CB-153（25%）的贡献较高。总的来说，与世界其他地区的先前研究相比，本研究中测量的污染物水平较高。BDE-209 的相对丰度表明研究区域存在十溴二苯醚的来源。主成分分析（PCA）表明，黄海还有其他 PBDE 来源。模式和 PCA 表明，研究区域的 PCB 污染来自相似的来源。此外，所有鱼类中∑（7）PBDEs（u/209）与∑（7）PCBs 的浓度呈强相关性（r=0.907，n=44）。
