| 摘 要： | 研究了新乡市污灌土壤受重金属污染的情况,同时对污灌土壤中所种植的蔬菜进行分析、测定.试验结果表明:污灌土壤中的Zn、Cu、Pb、Cr含量在国家标准以内,Ni、Cd含量超标,土壤已明显受到Ni、Cd的污染.按照国家食品卫生标准评价植物体中的重金属污染程度,结果显示:Cd、Cr、Pb、Cu、Zn的超标率分别为100%、100%、70%、60%、100%.重金属污染主要表现为Cd和Cr的污染.

| Abstract: | In order to study the heavy metal pollution situation in farmland irrigated by waste water in Xinxiang,the content of many heavy metals in plant was investigated.The soil extraction experiments showed that the concentration of Zn,Cu,Pb and Cr were lower than the national standard,and the content of Ni and Cd were over the standard.The irrigated soil was obviously polluted by the heavy metal Ni and Cd.According to national sanitary standard of food,the polluted degree of heavy metal was evaluted and the results indicated the concentration of Cd,Cr and Zn in all plants were over the standard;the concentration of Pb and Cu in some plants were over the standard;in other plants it was lower the standard.The heavy metal Cr and Cd that polluted plant were more serious. |
