| 摘 要： | 对抚顺西露天矿煤矸石山表层煤矸石进行多点取样,分析测定了矸石山表层煤矸石重金属Cd,Pb,Ni,Zn,Cr,Cu的含量及其形态特征。结果表明,煤矸石中Cd,Ni,Cu元素高出抚顺地区土壤环境背景值,其中Cd,Ni超出土壤环境质量2级标准。煤矸石重金属元素存在形态的分布规律总体与元素含量具有一致的变化规律,元素Cd,Pb,Ni,Zn,Cr,Cu的赋存形态普遍以残渣态、可还原态为主,可氧化态次之,弱酸可提取态比例最低。 |

| Abstract: | The weathered coal wastes were sampled at the surface layer in Fushun West Opencast coal mine dump,the content of Cd,Zn,Pb,Ni,Cr,Cu and their forms of the waste dump in surface rock were analyzied by ICP-AES.The results show that the contents of Cd,Ni,Co,Mn,Cu were beyond the limits in the region above the background value of soil environment in which Cd,Ni exceed soil environment quality criteria of 2th level.The changes of heavy metal elements and the presence of morphological features in the gangue rock showed some synchronization.Different class of heavy metals present in form of residual mainly of oxidizable fraction as well as reduced state content in the second,and weak acid extractable was the lowest. |
