摘要: 采用原子荧光光度法测定了30种东北主要绿化树种对大气中砷的吸收量。结果表明:这些树种均对砷具有一定的吸收能力,并且不同绿化树种的吸砷量有明显的差异,对砷吸收量高的树种有杏、榆树、垂枝榆和黄菠萝,可以作为砷污染较严重地区的绿化树种。另外在污染源和污染程度相似的地区,不同树种吸砷量也有很大的差异。

Abstract: The absorption capacity of 30 kinds of Northeast main greening tree species to As in the atmosphere were measured and studied by Atom Fluoresence Method.The results showed that all these greening tree species could absorb As pollutants to some extent,and the absorption capacity is obviously different according to pollution conditions and tree species.The greening tree species that have a high absorption content to As such as Prunus armeniaca,Ulmus pumila,Ulmus pumila var.pendula and Phellodendron amurense,could be acted as greening trees in serious areas of As pollution.Moreover,the absorption extent of different species to As were obviously different in similar areas of pollution origin and degree.

Key words: Northeast, greening tree species, absorption capacity, As
