兖济滕矿区煤矸石中微量元素的研究与识别

RESEARCH AND RECOGNITION TRACE ELEMENT OF EFFECT ENVIRONMENTAL IN THE GANGUE OF YANJITENG MINING AREA IN SHANDONG

摘要: 利用矿区煤矸石中38种微量元素含量的分析测试结果,研究了煤矸石中微量元素的含量水平和潜在的环境影响,识别出了Hg、Cd、As、Mo、Pb、Zn、Ba、U、Co等9种为兖济滕矿区煤矸石中具环境影响的微量元素,其中Hg、Cd、Mo、Pb、Zn五种元素对于大陆地壳丰度、全国表土背景值、山东省土壤背景值、矸石山附近土壤实测值显示高富集水平,为矿区煤矸石中极具环境影响的微量元素,应成为矿区环境综合治理的重点。这些具环境影响的微量元素,在矿区环境中的迁移性、累积性及生物可利用性,有必要进行深入研究。

Abstract: Using analysis result of 38 kinds of trace elements,the paper study the content and the latent environmental effect of trace element and identify Hg,Cd,As,Mo,Pb,Zn,Ba,U,Co as the trace element which effect environmental in the gangue of the mining area.The concentration of Hg, Cd,Mo,Pb and Zn is respectively higher than the mainland earth crust level,the national surface soil background value and the soil background value of Shandong Province and the five trace element extremely influence environmental.So we must mainly treat the five trace element.It is necessary to deep study these trace element of environmental effect which transfer,accumulate and biology use in the mining area environment.
