| 摘 要： | 长江口悬浮颗粒中重金属的化学形态分析结果表明，从徐六径到口外海滨，悬浮颗粒中铅、铜、锌的有机态含量总趋势是逐步下降，但在最大浑浊带出现一个峰值；受潮流作用较强的南槽最大浑浊带比受径流作用较强的北槽最大浑浊带有机态重金属的含量高得多，这种现象洪季比枯季尤为显著；最大浑浊带内，南槽最大浑浊带铜，锌的有机态含量显著增加，与长江口其它河段有明显的差别。

| Abstract: | The speciation analysis of heaVy metals in suspended particles shows that the content of Pb,Cu, and Zn in organic form gradually decreases seaward from Xuliujin to the outside seashore but appears peak value in the maximum turbidity zone. The content of organic heaVy metals in South Channel, controlled mainly by tide current, is higher than that in Northe Channel controlled mainly by runoff. This phenomenon is more remarkable in dry season than in flood season. Unlike other reaches of the Changjiang Estuary, the orgamic contont of Cu and Zn obviously increases in the maximum turbidity zone of South Channel. |
