摘要
对冷水江锑矿区4个采样点土壤重金属含量进行了测定和分析,运用地积累指数法、单因子指数法评价了该区土壤重金属污染程度。结果表明,矿区土壤6种重金属元素的平均含量均超出湖南省土壤背景值和全国土壤背景值,土壤受Sb污染最严重,其次是Cd污染,伴有中轻度As、Cu、Pb污染,Zn污染不明显。
Heavy metal concentration of soil and dominant plants in antimony mine of Lengshuijiang from four contaminated sites were quantitatively analyzed. The state of pollution was evaluated by the geoaccumulation index and single factor index of heavy metals contamination in the study area. The results showed that tall the average contents of the six heavy metals had exceeded the background value of heavy metals in China and Hunan. The soil of this mine was seriously polluted by Sb and Cd, as well as As, Cu and Pb in some places.
