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

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.
