摘要： 本文对广西锰矿区、铅锌矿区和金矿区土壤和植物的重金属含量进行了调查分析。在所调查的24种植物中,Cu含量在30.8~183.8mg/kg范围,Mn含量在143.6~27514mg/kg范围,Zn含量在113.3~1773mg/kg范围。相对于正常条件下生长的普通植物来说,其Cu、Mn和Zn含量都较高。生长在锰矿区的狗牙根、香附子和菜蕨中Mn的含量分别达到27514、16144和11516mg/kg,相应的富集系数为11.4、6.7和4.8。这3种植物均达到Mn超富集植物的相关标准,因此是潜在的Mn超富集植物。

Abstract: In order to screen the potential hy peraccumulators, the concentrat ions of Cu, Mn and Zn in 24 dominant plants grown in areas near abandoned Mn, Pb/Zn and Aumines in Nanning City of Guangxi Province were investigated. The results show that most plants contained high concent ration of metals resulting from the increased metal concent rations in the soils near the mines. Mn concentration f Mn-mine soil (2415.0 mg/kg) , w hich was 14.0 times greater than Mn backg round value of Guangxi soil, was higher than that of Pb/Zn-mine soil (687.5 mg/kg) and Au-mine soil (487.2 mg/kg). Most of the investigated plants grown on the Mn mine contained higher concentration Mn in the aboveground tissue (909.0~27514.0 mg/kg) than that (143.6~4388.0 mg/kg ) grown on other mines.
