中文摘要：

在从 Zhujiang 河河口的水列的 polybrominated diphenyl (PBDE ) 的空间、时间、垂直的分布被检验，并且在粒子和溶解阶段之间的 PBDE 的分区行为在现在的学习被调查。结果证明水里的 PBDE 集中的分布与采样季节变化了。当略有盐味的水在河口是主导的时，在水样品的 PBDE 集中在 2005 年 5 月是更低的，比在 2005 年 10 月，当从河流量的新鲜的水统治了河口时。在 2005 年 10 月的 PBDE 的空间分发显示河流量是主要模式在水里输入 PBDE 到 PBDE 的河口，和集中可能被溶解器官的碳(文档) 依赖。在 2005 年 5 月的 PBDE 的空间、垂直的分布是相对同类的，并且 SPM 是在这采样时间控制 PBDE 的层次上的主要因素。文档和停靠港能在决定分发起某些作用，在粒子和溶解阶段之间的 PBDE 的分区，而是他们的效果与水性质变化。

英文摘要：

The spatial, temporal, and vertical distributions of polybrominated diphenyl ethers （PBDEs） in water columns from the Zhujiang River Estuary were examined, and the partition behavior of PBDEs between particle and dissolved phases was investigated in the present study. The results show that the distributions of PBDEs concentrations in the water varied with the sampling seasons. The PBDEs concentrations in water samples were lower in May 2005, when the brackish water was dominant in the estuary, than in October 2005, when fresh water from river runoff dominated the estuary. The spatial distribution of PBDEs in October 2005 indicated that the river runoff was the major mode to input PBDEs to the estuary, and the concentration of PBDEs in water might be dissolved organic carbon （DOC） dependence. The spatial and vertical distributions of PBDEs in May 2005 were relatively homogeneous, and SPM was the major factor on controlling the levels of PBDEs in this sampling time. Both DOC and POC could play certain roles in determining the distribution and partition of PBDEs between particle and dissolved phases, but their effects varied with the water properties.
