| 摘 要： | 作者采用阳极溶出伏安法测定大亚湾珊瑚礁痕量金属铜、铅、镉的含量 ,并讨论了相关的影响因素。测定结果发现 :A组、B组珊瑚礁礁体中铜、铅、镉的含量从里到外有递增的趋势 ,这与近年来大亚湾水体中铜、铅、镉含量的变化是一致的。而 A组珊瑚礁变化明显 ;B组珊瑚礁礁体中铜、铅、镉含量呈现较复杂的变化。分析认为 ,这是因珊瑚礁的形成受多种因素影响所致 :(1)海水组成对珊瑚礁化学成分的影响 ;(2 )海洋生物种类、数量及其矿物组成是制约元素分布的主要因素 ;(3)陆源碎屑组分对大亚湾珊瑚礁的化学组成有一定的影响。各因素在不同情况下所起的作用不同。

| Abstract: | Trace metals Cu, Pb, Cd of coral reef in Daya Bay, China were determined by means of polarography. We found out that the concentrations of Cu, Pb, Cd in coral reef had a trend to increase from inside to outside in the two series of samples, especially in Group A, and this was consistent with the content change of those metals in neighbouring seawater. But there was a more complex trend in samples of Group B. We considered many factors that influence the forming of coral reef, such as the concentrations of trace metals in seawater where coral reef grew, the quantity, category and which mineral compose of marine organisms, the biodetritus from coast and so on. |
