Abstract

The concentrations and distribution of polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane (HBCD), and tetrabromobisphenol A (TBBPA) were investigated in 28 sediment samples collected from Taihu Lake, Eastern China. The results showed that all three classes of compounds were detected in 28 sediment samples but that PBDEs were the main contaminants in the study area. The total PBDE concentrations ranged from 3.77 to 347 ng/g dry weight (dw) with a mean value of 72.8 ng/g dw, whereas the concentrations ranged from 0.168 to 2.66 and from 0.012 to 1.30 ng/g dw for HBCD and TBBPA, respectively. In all of the sediment samples, BDE-209 was the predominant congener, accounting for 95.9 to 98.6 % of the total PBDEs, which indicated that commercial mixtures of deca-BDEs were the main sources of PBDE contamination. Higher concentrations of PBDEs were found in samples collected from Meiliang Bay and Gonghu Bay near the inflow river, which suggested that inflow runoff might play an important role in the PBDE levels in Taihu Lake sediments.

摘要

对从中国东部太湖采集的28个沉积物样本中的多溴二苯醚（PBDEs）、六溴环十二烷（HBCD）和四溴双酚A（TBBPA）的浓度及分布进行了调查。结果表明，在28个沉积物样本中均检测到了这三类化合物，但PBDEs是研究区域内的主要污染物。PBDEs的总浓度范围为3.77至347纳克/克干重（dw），平均值为72.8纳克/克dw，而HBCD和TBBPA的浓度范围分别为0.168至2.66纳克/克dw和0.012至1.30纳克/克dw。在所有沉积物样本中，BDE - 209是主要同系物，占总PBDEs的95.9%至98.6%，这表明十溴二苯醚的商业混合物是PBDE污染的主要来源。在从入流河流附近的梅梁湾和贡湖湾采集的样本中发现了较高浓度的PBDEs，这表明入流径流可能在太湖沉积物中的PBDE水平中起重要作用。
