摘    要:为揭示多溴二苯醚(PBDEs)在东北主要河流流域内的污染现状,通过采集该地区流域内表层沉积物样品,采用GC-NCIMS技术对沉积物中41种PBDEs同类物进行分析.结果发现沉积物中BDE209含量低于检出限,其它40种PBDEs同类物总含量(不包含BDE209)范围(干重)为0.91~17.67 ng·g-1.其中第二松花江吉林市上游和下游沉积物样品中PBDEs的检出含量最高,分别为15.86 ng·g-1、17.67 ng·g-1,以BDE207和BDE47为主,分别占PBDEs总量的86.5%和76.6%;其它河流沉积物中各同族体含量差异并不明显.实验结果与国内外最近的文献报道值相比较,再结合生态风险分析显示,东北主要河流沉积物中PBDEs的含量处于低污染水平,目前不存在生态风险.

关 键 词:多溴二苯醚  沉积物  生态风险  暴露水平  污染  东北主要河流

Abstract:To investigate the polybrominated diphenyl ethers (PBDEs) pollution status, sediment samples were collected from major rivers in northeast China. Contents of 41 PBDEs congeners in sediments were measured using GC-NCI-MS. BDE209 was not detected, measured level of total PBDEs (excluding BDE209) ranged from 0.91 to 17.67 ng·g-1 dry weight, the highest concentrations of PBDEs were detected in the sediment samples from upstream and downstream of Jilin City in the Second Songhua River Basin, with 15.86 and 17.67 ng·g-1. BDE207 and BDE47 were the predominant PBDE congeners, with their concentrations accounting for 86.5% and 76.6% of the total PBDEs concentration measured in the samples. Each congener content difference was not obvious in other river sediments. PBDEs levels monitored in the present study were compared to those reported recently for districts located at home and abroad, and with ecological risk analysis. PBDEs content is at a low level in sediments of Northeast China River Basin and there is no ecological risk.
Keywords:PBDEs  sediment  ecological risk  exposure level  pollution  Northeast China River Basin
