摘要
讨论了自然条件下岩石、矿物等化合物化学反应机理及主要制约因素 ,分析了自然界金属元素向环境释放的基本机制 ,强调水在金属元素从其原始载体———矿物、岩石进入环境过程中的作用。
The mechanism and factors of chemical reaction under the condition on the earth surface between compounds, rocks and minerals, are important in the study of metal pollution. Weathering is the key step for metals to mobilize and translate as ion species in environment. In this paper, metal sulphides are discussed as examples for the relative reactions affected by Eh、 pH、 t、 p、α i etc.It is summarized that physical and chemical conditions of the environment are controlling factors in the process of metal pollution. Water plays an important role in the process of weathering and pollution of metals and is the main carrier of these metals in the environment.
