Abstract

Marine sediments collected from the Zhujiang (Pearl) River Estuary (ZRE) and South China Sea (SCS) were utilized to study the occurrence and spatial distribution of tetrabromobisphenol A (TBBPA) and hexabromocyclododecane (HBCDD). The levels of TBBPA and HBCDD in sediments ranged from not detected (nd) to 6.14 ng/g dry weight (dw) and nd to 0.42 ng/g dw. TBBPA concentrations in marine sediments were substantially higher than HBCDD. The concentrations of TBBPA and HBCDD in the ZRE sediments were significantly greater than those in the SCS. α-HBCDD (48.7%) and γ-HBCDD (46.2%) were the two main diastereoisomers of HBCDD in sediments from the ZRE, with minor contribution of β-HBCDD (5.1%). HBCDD were only found in one sample from the northern SCS. The enantiomeric fraction of α-HBCDD in sediments from the ZRE was obviously greater than 0.5, indicating an accumulation of (+)-α-HBCDD. The enantiomers of HBCDD were not measured in sediments from the SCS. This work highlighted the environmental behaviors of TBBPA and HBCDD in marine sediments.

珠江口和南海沉积物中的四溴双酚 A 和六溴环十二烷

利用从珠江口（ZRE）和南海（SCS）采集的海洋沉积物研究了四溴双酚 A（TBBPA）和六溴环十二烷（HBCDD）的发生和空间分布。沉积物中四溴双酚 A 和六溴环十二烷的含量范围分别为未检测到 (nd) 至 6.14 纳克/克干重 (dw) 和 nd 至 0.42 纳克/克干重。海洋沉积物中的三溴双酚 A 浓度远高于六溴环十二烷。在 ZRE 的沉积物中，α-六溴环十二烷（48.7%）和γ-六溴环十二烷（46.2%）是六溴环十二烷的两种主要非对映异构体，β-六溴环十二烷（5.1%）含量较少。六溴环十二烷仅出现在 SCS 北部的一个样本中。在 ZRE 的沉积物中，α-六溴环十二烷的对映异构体部分明显大于 0.5，表明 (+)-α-HBCDD 正在积累。在 SCS 的沉积物中未测出六溴环十二烷的对映体。这项工作强调了三溴双酚 A 和六溴环十二烷在海洋沉积物中的环境行为。

期刊介绍： Founded in 1982, Acta Oceanologica Sinica is the official bi-monthly journal of the Chinese Society of Oceanography. It seeks to provide a forum for research papers in the field of oceanography from all over the world. In working to advance scholarly communication it has made the fast publication of high-quality research papers within this field its primary goal. The journal encourages submissions from all branches of oceanography, including marine physics, marine chemistry, marine geology, marine biology, marine hydrology, marine meteorology, ocean engineering, marine remote sensing and marine environment sciences. It publishes original research papers, review articles as well as research notes covering the whole spectrum of oceanography. Special issues emanating from related conferences and meetings are also considered. All papers are subject to peer review and are published online at SpringerLink.
