| 摘 要： | 2005年10月,采集了乐安江及其支流漫滩区表层土中的优势植物--稗草,并测定了其中6种重金属(Cd、Cr、N i、Cu、Pb、Zn)的含量。流经亚洲最大露天铜矿(德兴铜矿)的乐安江,其三条支流由于被德兴铜矿的酸性矿山废水(AMD)和一个活性炭厂排出的废液所污染,以至其漫滩区表层土中的稗草含有高浓度的Cd、Cu、Pb、Zn。稗草中6种金属的生物体内累积性按下列次序退减:Cd>Zn>Cu>Pb>N i>Cr,这与它们在环境中的迁移性相一致。 |
| 关 键 词： | 漫滩表层土 稗草 重金属 采矿行为 乐安江 |

| Abstract: | Six metals(Cd,Cr,Ni,Cu,Pb and Zn) were determined in barnyardgrass of Le An River,which runs through the largest outcrop copper mine(Dexing Copper Mine) in Asia,and its tributaries in Oct.2005.Three tributaries contaminated by AMD from mining activities or discharges from an activated carbon factory have high Cd,Cu,Pb or Zn contents in barnyardgrass.Bioaccumulation of the six metal species in floodplain barnyardgrass decreases following the order: Cd>Zn>Cu>Pb>Ni>Cr,consistent with environmental mobility of ... |
