摘要
以株洲市清水塘重金属污染工业区14种典型植物为研究对象,采用原子吸收分光光度法测定其Cu、Cd、Pb、Zn 4种重金属含量,研究植物对重金属的分布、富集和转运特性。结果表明,14种植物对修复复合型土壤重金属污染有较好的应用前景。其中,马兜铃(Aristolochia debilis)对Cu、Pb、Cd、Zn,臭牡丹(Clerodendrum bungei)、接骨草(Sambucus chinensis)对Pb、Cd、Zn,山莴苣(Lagedium sibiricum)对Pb、Zn,狗尾草(Setaria viridis)、牛皮消(Cynanchum auriculatum)对Cd,空心莲子草(Alternanthera philoxeroides)对Cu的地上部分富集系数和转运系数都大于1。可将这些植物作为先锋植物用于相应重金属污染严重区域。
This paper focused on the distribution, bioaccumulation and translocation of heavy metal from soil to plants. Based on the concentrations of heavy metals, including Cu, Cd, Pb and Zn, determined by atomic absorption spectrophotometry, fourteen typical plants were studied in the Qingshuitang heavy metals polluted area in Zhuzhou. The results showed that these species had promising prospects on repairing combined heavy metals soil pollution. More specifically, the bioconcentration factor and transfer factor about Aristolochia debilis to Cu, Pb, Cd and Zn, Clerodendrum bungei and Sambucus chinensis to Pb, Cd and Zn, Lagedium sibiricum to Pb and Zn, Setaria viridis and Cynanchum auriculatum to Cd and Alternanthera philoxeroides to Cu were all greater than 1. These plants could apply on the heavy metal pollution regions as pioneer plants.
