| 摘 要： | 采用自制滚筒式自动采样器采样，研究了珠江口水域微表层中Ｆｅ，Ｍｎ，Ｃｕ，Ｐｂ，Ｚｎ，Ｃｄ的含量、分布变化及富集状况。并通过颗粒痕量金属／颗粒Ｆｅ比值计算，探讨了痕量金属的来源。结果表明：Ｃｕ，Ｐｂ，Ｚｎ，Ｃｄ在微表层的平均富集系数分别为２．３，１．４，３．０和１．９。颗粒态Ｆｅ，Ｍｎ的平均富集系数为１．１和０．９。各种金属有明显的季节和空间变化，有各种不同的来源。

| Abstract: | he surface micro-layer samples of Zhujiang River Mouth are collected through a rotatory drum sampler made by ourself, the levels, distributions,variations and enrichment conditions of Cu,Ph, Zn and Cd are studied and the origins of these metals are detected through calculation of ratios of the particulate trace metals/particulate Fe. The result demonstrates that the mean enrichment coefficients of Cu, Ph, Zn and Cd are 2. 3,1. 4, 3. 0, and 1. 9 respectively in the surface microlayer and those of particulate Fe and Mn are l, 1 and 0. 9. All the metals have obvious temporal and spatial variations and are of different origins. |
