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。 The authors used anodic stripping voltammetry to measure trace amounts of copper, lead and cadmium in Daya Bay coral reefs, and discussed the related factors. The results showed that the content of copper, lead and cadmium in reefs of groups A and B tended to increase from the inside to the outside, which was consistent with the changes of copper, lead and cadmium in Daya Bay water bodies in recent years. While the coral reefs in group A changed obviously. The contents of copper, lead and cadmium in coral reefs in group B showed more complicated changes. This is attributed to the fact that the formation of coral reefs is affected by many factors: (1) the influence of seawater composition on the chemical composition of coral reefs; (2) the species, quantity and mineral composition of marine organisms are the major constraints on the distribution of elements; 3) Terrigenous detritus components have a certain impact on the chemical composition of the Daya Bay coral reefs. The factors play different roles in different situations.
