摘 要 ：一、前言 近年来,随着采矿、冶炼以及镉处理等工业的发展,不仅有大量废水中的镉通过土壤——植物进入食物链,给人造成危害,而且还有大量含镉粉尘污染大气环境,通过呼吸及消化道进入人体,直接给人以危害。因此,镉污染及其防治问题引起了人们极大的关注。国内外对水稻、小麦、玉米及蔬菜、牧草中镉的吸收积累规律作了不少研究(董克虞等,1981;陈铨荣等,1978:陈涛等,1980:Reddy等,1977)。

Abstract:1. Leaves and lenticels on stem of woody-plants play an important role in absorbing cadmium from atmosphere. A number of broad-leaved trees have a rate of about 60 percent in absorption of cadmium. Roots of trees also play an important role in the absorption of Cd from soil and their absotrp-tioa fate is about 50 percent. .2. The pollutant Cd of a heavy metal absorbed from atmosphere can remove in the organs of plants. The law of removal is that Cd in root removes less. But this is variable in species of tr...
