闽北铅锌矿附近土壤重金属含量分布特点的研究

The trait of distribution of heavy metal of the soil near to the mining area with Lead and Zinc in the Northern Fujian Province

通过分析闽北主要县市土壤重金属(铅、锌、铜、镉)含量及其分布特征,结果显示铅、锌、镉的分布在不同的用地类型中分布具有极显著的差异,而铜在不同用地类型中没有显著差异。通过各种重金属含量与标准相比较,用内梅罗综合污染指数研究其各种重金属在环境中的所起的作用得出铅、锌、镉是主要的原因,今后将作为污染防治主要目标。

The study showed that the significant differences of distribution of Zinc, Copper, Lead, Cadmium in the different types soil for use by having analyzed the content and characteristics of heavy metals in the Northern Fujian Province, but Copper not to so. Comparing with the national standard of heavy metals in the soil, it concluded that three metals, Zinc, Lead and Cadmium, which are the main fact of acting on the environment with the analyzing method of N.C.Nemerow index, will be the major aim of prevention and treatment in the areas.
