Shuitu Baochi Xuebao, 2011 通过野外采样与室内实验分析煤矸石重金属的释放活性,并利用潜在生态风险评价法分析煤矸石山周边土壤污染及其潜在生态风险特征。结果表明,实验用煤矸石中重金属主要以残渣态存在,Cu、Zn、Pb、Cr和Cd的残渣态分别占其总量的56.86%,53.27%,72.01%,68.61%和75.93%,不易发生释放迁移,但少量酸溶态和氧化物结合态重金属易被淋溶后在矸石山周围土壤中累积并造成重金属污染。煤矸石山周边土壤重金属含量随着距离的增加呈现减少趋势,表明周边土壤受到煤矸石重金属污染,并且在土壤表层重金属含量最高 ...

, 2003 沉积物中的酸挥发性硫化物(AVS)是预测厌氧沉积物中重金属生物有效性的重要参数,SEM/AVS大于1时沉积物中重金属具有潜在生物毒性,小于1时则无生物有效性. 本文研究了东湖三个不同污染负荷的站点的同步提取金属SEM(Cu, Zn, Pb, Cd, Ni, Co, Ag, Cr)和SEM/AVS的深度分布,研究表明东湖沉积物中主要重金属是Zn, Cr和Cu,约占SEM总量的90%.
