• 摘要：随着冶金工业的发展,我国大气中重金属污染日趋严重。防治方法,除必须采取的工业治理措施外,还应充分发挥绿色植物的自净作用。 绿色经济植物对大气中重金属的吸收和积累及在植物体内的分配规律,这方面研究目前在国内还不多见。我们选材经济植物的目的是为重金属污染地区寻找一条切实可行的生物防治途径,从而防止重金属污染的粮食、蔬菜、水果等通过食物链进入人体。

• Abstract：The absorption and the accumulation of copper, lead and arsenic by three species of economic plants (Gossypium herbaceum, Ricinus communis and Boehmeria nivea) were studied by applying the metal-added dust on the leaves and soil in pot experiments. The results indicated that the metals applied on soi were mainly accumulated in the roots and those spread were in the leaves. The very small portions of the metals were transferred into the fruits. The abilities of the plants for absorbing the metals were different from one another.

• Key words：soil  heavy metals  absorption  accumulation
