Abstract

The uptake and distribution of four heavy metals, including copper (Cu), cadmium (Cd), lead (Pb) and zinc (Zn), and those of total phosphorus (TP) in 30 plants in North China were investigated through pot trial experiments. Accumulation and distribution of heavy metals or TP were associated with plant species, tissues, metal elements and pollutant loading. The highest amount of heavy metal and TP accumulation was found in the whole plants of Hylotelephium erythrostictum (Miq.) H. Ohba (C1) and Chlorophytum laxum R. Br. (L4), respectively. Considering the biological concentration factor, translocation factor, retention factor and biomass indices, C1 is the suitable plant for Cd and Cu uptake, whereas Hosta plantaginea (Lam.) Aschers (L3) and Viola verecunda A. Gray (V1) are the suitable plants for Pb removal. Rehmannia glutinosa (Gaetn.) Libosch. ex Fisch. (S1) and L4 can be chosen for Zn and TP removal, respectively. Cluster analysis was applied to select suitable plants for heavy metal and TP removal. Results showed that C1, L4 and Pennisetum alopecuroides (L.) Spreng (G1) have a good capability of accumulating heavy metals and TP. Results demonstrated that the plant species rather than the families considerably influenced the accumulation of pollutants.

30个生物保留工厂中合成雨水中的Cu，Cd，Pb，Zn和总P的积累。

摘要

通过盆栽试验研究了华北地区30种植物中铜（Cu），镉（Cd），铅（Pb）和锌（Zn）以及总磷（TP）的四种重金属的吸收和分布。重金属或总磷的积累和分布与植物种类，组织，金属元素和污染物的含量有关。在整个植物中，重金属和TP的积累量最高。Hylotelephiumerythrostictum（Miq。）H. Ohba（C1）和Chlorophytum laxum R. Br。（L4）。考虑到生物浓度因子，转运因子，保留因子和生物量指标，C1是吸收Cd和Cu的合适植物，而Hosta plantaginea（Lam。）Aschers（L3）和Verola verecunda A. Gray（V1）是去除Pb的合适植物。熟地黄（Gaetn。）Libosch。前Fisch。可以选择（S1）和L4分别去除Zn和TP。应用聚类分析来选择合适的工厂以去除重金属和总磷。结果表明，C1，L4和狼尾草（L.）Spreng（G1）具有良好的重金属和TP积累能力。结果表明，植物物种而不是科系在很大程度上影响了污染物的积累。
