几种重金属（Cd、Cr、As）在玉米植株中的分布研究
Research on the D istribution of Heavy Metal in Corn Plants
摘要
Abstract
The contents of heavy metals (Cr,Cd,As)in maize plant and soil collected from somewhere in Zhuzhou were measured by ICP plasma method. Preliminary study was made on the Characteristics of heavy metal accumulation in differ-ent organs of Maize. The results showed that:(1 )the soil was contaminated by As at middle-grade,by Cd at severe -grade,(2)the contents of heavy metal in plant showed the order of root>leaf >stem,(3)the accumulative coefficient or-der was Cd>Cr>As,(4)the result also showed that maize plant was tolerated to As,(5)Cr of stem were significant nega-tive correlation with the same elements in the roots. While Cd in stem and leaf were significant positive correlation with the same elements in the root.关键词
