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.
