采用电感耦合等离子体发射光谱(ICP-OES)法同时测定成都市三环内表层土壤13种金属元素含量与分布.研究显示,重金属元素As、Cr、Cu、Ni、Pb、Zn平均含量分别为24.3mg/kg,154.0 mg/kg,32.8 mg/kg,31.4 mg/kg,64.9 mg/kg,165.1 mg/kg.Mn、Mo、Fe平均含量分别为400.1 mg/kg,10.7 mg/kg,18911 mg/kg.Sr 74.0 mg/kg、Sb 4.9 mg/kg、Co 13.7 mg/kg、Sc 5.9 mg/kg.采用单项污染指数法和内梅罗综合污染指数法来评价土壤重金属污染程度,并针对表层土壤金属污染状况进行了讨论.
採用電感耦閤等離子體髮射光譜(ICP-OES)法同時測定成都市三環內錶層土壤13種金屬元素含量與分佈.研究顯示,重金屬元素As、Cr、Cu、Ni、Pb、Zn平均含量分彆為24.3mg/kg,154.0 mg/kg,32.8 mg/kg,31.4 mg/kg,64.9 mg/kg,165.1 mg/kg.Mn、Mo、Fe平均含量分彆為400.1 mg/kg,10.7 mg/kg,18911 mg/kg.Sr 74.0 mg/kg、Sb 4.9 mg/kg、Co 13.7 mg/kg、Sc 5.9 mg/kg.採用單項汙染指數法和內梅囉綜閤汙染指數法來評價土壤重金屬汙染程度,併針對錶層土壤金屬汙染狀況進行瞭討論.

This paper surveys the concentration and distribution of 13 kinds of metal in surface soil within third ring of Chengdu by ICP-OES.The average values of heavy metals As,Cr,Cu,Ni,Pb,Zn are 24.3mg/kg,154.0 mg/kg,32.8 mg/kg,31.4 mg/kg,64.9 mg/kg,165.1 mg/kg.The average value of Mn,Mo,Fe are 400.1 mg/kg,10.7 mg/kg,18911 mg/kg.The average value of Sr,Sb ,Co,Sc are 74.0 mg/kg,4.9 mg/kg,13.7 mg/kg,5.9 mg/kg.By adopting the Single Factor Index and Nemerow Multi-Factor Index Methods ,the pollution indices were calculated to assess the pollution extent,and discusses the heavy metal pollution status in surface soil.
