摘要
为了研究工业和交通对降尘中As、Cd、Cr、Cu、Pb和Zn的影响,在上海市杨浦区设置11个采样点,对采样点降尘中砷和5种重金属元素的含量进行了调查,并分析工业和交通对降尘中砷和5种重金属元素的影响。结果表明工业和交通影响区域降尘中砷和5种重金属元素的含量,相对于土壤背景值,降尘中Cd、Cu、Zn三种重金属的含量较高,其含量分别为土壤背景值的16.4、42.7和16.0倍。使用地积累指数Igeo法和富集因子法分别评价降尘中砷和5种重金属元素的污染状况,相似的结果表明砷和5种重金属元素在降尘中存在不同程度的污染。
In order to study industry and traffic effect on As,Cd,Cr,Cu,Pb and Zn,11 sampling sites were set at Yangpu District,Shanghai for the analysis of arsenic and five heavy metals in the dustfall.Results indicated that content of Cd,Cu and Zn in dustfall was higher than those in soil background,with 16.4 times,42.7 times and 16.0 times of soil background.Assessment of pollution of As and five heavy metals in dustfall,similar results were showed in Geoaccumulation Index and enrichment factor with different pollution grades.
