    摘要:

    选取葫芦岛市杨家杖子区多家个体钼矿周边果园土壤样本60个、果园红富士苹果样本60个,经消解处理后用等离子体发射光谱仪(ICP-AES)测定土壤和水果样本中Pb、Ni、Cu、Cr、Zn、Cd、As、Mo、Hg金属元素含量,并对重金属污染状况进行全面系统评价。评价结果表明,果园土壤Cd、As和Hg的污染严重。土壤中Pb、Ni、Cu、Cr和Zn污染也比较重。污染程度为:Cd>As>Hg>Pb>Zn>Cr>Cu>Ni。并给果树造成影响,所产水果也遭到轻微污染,污染程度大小基本与土壤污染结果相一致。

    Abstract:

    60 soil samples from orchards and 60 fruit samples of Fuji apples near private-owned molybdenum mines in the area of Yangjia-zhangzi of Huludao City were collected.After the samples were dissolved,ICP-AES was used for determining the levels of Pb,Ni,Cu,Cr,Zn,Cd,As,Mo and Hg.Heavy metal pollution was thoroughly assessed.The results indicated that the pollution of Cd,As and Hg in soil was serious.Pb,Ni,Cu,Cr and Zn were also over the standard.The amount of varies heavy metal was in such sequence: Cd>As>Hg>Pb>Zn>Cr>Cu>Ni.Accordingly,fruit trees were influenced and fruits were polluted to some extent.The pollution level of fruits was the same as it was in soil.
