| 摘 要： | 重金属在环境中的残留、累积常常引起一些环境问题Schroeder,1965;Lewis,1969;Nandi,1969;Tsuchiya,1969;Friberg,1974。在植物土壤系统中,由于重金属被土壤强烈吸附和固定,很容易在土壤中残留累积,引起生长的植物吸收过多的重金属而造成对人体健康的威胁(Friberg,1974;Lagerwerff,1972;Lisk,1972;Page,1973;Page,

| Abstract: | The uptake rate of Hg and As of rice is greater than that of wheat. But the uptake rate of Cu, Pb, Zn and Cd of rice is lower than that of wheat, and their order is: Zn> Cd>Cu>As>Hg>Cr>Pb.The sequence of some heavy metals contained in various organs of rice and wheat is as follows: roots>stems leaves>grains. The amount in vegetables also varies with different kinds of vegetable. Pb is obstructed in roots, and is difficult to be transported into stems, leaves and grains. It is easy for Cd to be absorbed into... |
