摘要
通过污染土壤上的12种植物的调查和定量分析,发现它们对重金属Cu、Cd、As、Zn、Pb有不同的吸收和富集能力。主要表现为蜈蚣草(PterisvittataL.)对Cu、Cd、As都有吸收,特别是对As的吸收达到超富集的水平;野苎麻(Boehmeriafrutescensvar.viridula)、野蔷薇(Rosamultiflora)对Cd的富集能力较强;空心莲子草(Alter nantheraphiloxeroides)对Zn、赤车使者(Elatostemainvolucratum.)对Zn、Pb有较强的吸收能力。
12 kinds of plants in the polluted soil were investigated and quantatively analyzed. It was found that the plants had different abilities of absorption and accumulation of Cu, Cd, As, Zn, Pb. Pteris vittata absorbed Cu, Cd and As, And its absorption of As reached the super-accumulation level.Boehmeria frutescens, Rosa multiflora had high accumulation abilities of Cd. and Alternanthera philoxeroides showed high accumulation ability to Zn and Elatostema involucratum to Zn、Pb.
