摘要
本文讨论了水体中植物穗花狐尾藻和黑藻对重金属Cu、Zn、Pb、Cd、Hg、Cr的吸收。分别在重金属元素种类、含量不同的水体中培养植物,定时检测水体中重金属含量的变化,并分析植物体内重金属含量,研究了水生植物吸收水体中重金属的能力。
This paper piscusses the absorption of heavy metals (Cu, Zn, Pb, Hg, Cr) by the aquatic plants of Myriophyllum spicatum L. and Hydrilla verlicillata (L. f)Royle in water. Plants are cultured respectively in water which contains various kinps of and different contents of heavy metal elements. The contents of heavy metal elements changed in water are regularly determined. The contents of the heavy meta Is in these plants bodies are analysed. The ability of aquatic plants to absorb heavy me- tals in water is studied.
