海河渤海湾地区沉积物、鱼体样品中多溴联苯醚的水平与分布

PBDEs in sediments and crucians of Haihe River and Bohai Bay

从海河、渤海湾水域内采集了沉积物和鱼体（鲫鱼）样品,采用气相色谱/质谱（GC/MS）方法测定了样品中的多溴联苯醚（PBDEs）。结果表明,沉积物（以干重计）和鱼体（以干重计）中PBDEs的检出水平分别为0.35～5.53、6.81～35.50 ng/g,其中相对含量较高的PBDEs单体为BDE-28和BDE-47。鱼体内脏组织中PBDEs的检出水平较肌肉组织中的PBDEs要高,表明其更容易富集PBDEs。

Sediment and crucian samples collected at 11 and 6 sampling points in lower Haihe River along with sediment samples collected at 9 sampling points in inner Bohai Bay were analyzed by GC/MS for assessment of concentration and distribution of polybrominated diphenyl ethers （PBDEs） in coastal Bohai Bay. The total PBDEs in the sediment samples ranged from 0. 35～5.53 ng/g （dry weight）, with more found in the river samples, and the total PBDEs in the crucians samples ranged from 6.81～35.50 ng/g; both were lower than total PBDEs present in comparable sediment and fish samples of most industrial countries. BDE-28 and BDE-47 were the dominam congeners in all samples. The PBDSs were more readily accumulated in tripe than muscle of the fish as much more PBDEs were found in the former.
