8种微量元素镉(Cd)、铅(Pb)、铁(Fe)、锌(Zn)、锰(Mn)、铜(Cu)、汞(Hg)和 砷(),,在沉积物和水中;在加纳阿曼西地区(6度;28度;北纬;1度;53度;西纬)沿着两条河道进行了四个手工和小规模采矿(ASM)地点的评估。2011年5月至2011年7月。在每个地点的五个不同的点上随机抽取三份水和沉积物样本原子吸收分光光度计。利用地质堆积指数(Igeo)评价，沉积物发现受到不同程度的Cu污染(未污染到中度污染/中度污染);汞(未污染到中度污染/中度污染)和砷(中度污染/中度到强烈污染)。富集系数(EF)表明人类活动对所有地区沉积物中Cd和Pb的影响，而对其余微量元素的影响仅限于部分地区。 The elements are major sediment pollutants ( EF > 2) in one or more of the localities. The Igeo and EF gave diverse status of the sediment qualities of the localities. Cd, Pb, Hg and As water concentrations in the four artisanal mining localities were all found to be above the WHO maximum acceptable of levels for drinking water. Inhabitants in the mining localities face the risk of getting various diseases by drinking the waters contaminated with the trace elements.
