摘要
应用试验及文献数据计算了东湖沉积物中酸挥发性硫化物 (AVS)垂直分布模型的参数值 ,并进行了参数的相关性分析 .结果表明 ,AVS含量是沉积物中有机质的分解、AVS的沉淀、溶解及氧化共同作用的结果 ,较好地解释了东湖三个污染状况不同站点AVS垂直分布的差异 ,从而为应用AVS判断沉积物重金属生物有效性提供了科学依据 .
The parameters of AVS vertical distribution model applied to Donghu lake sediments was calculated.Also,correlation of the parameters was analysis.The results show that the AVS contents were controlled by the process of organic decomposition,AVS deposition,dissolution and oxidation.Using this results,the difference of AVS vertical distributions among three locations with different eutrophic level of Donghu lake can be explained well.
