对淮安市某垃圾填埋场土壤中13个采样点中典型重金属 Cr、Pb、As、Hg、Cd、Cu、Zn 的含量进行了调查，采用单因子污染指数、综合污染指数及 Hakanson潜在生态风险指数法评价了土壤中典型重金属对其所在环境的污染程度，对周围环境造成的潜在生态风险影响。结果表明，研究区域内重金属含量均未超过《土壤环境质量标准》（GB 15618-1995）二级标准。主要的潜在生态风险因子为 As，潜在生态风险因子大小顺序为 As＞Hg＞Cd＞Cu＞Cr＞Pb＞Zn。
對淮安市某垃圾填埋場土壤中13箇採樣點中典型重金屬 Cr、Pb、As、Hg、Cd、Cu、Zn 的含量進行瞭調查，採用單因子汙染指數、綜閤汙染指數及 Hakanson潛在生態風險指數法評價瞭土壤中典型重金屬對其所在環境的汙染程度，對週圍環境造成的潛在生態風險影響。結果錶明，研究區域內重金屬含量均未超過《土壤環境質量標準》（GB 15618-1995）二級標準。主要的潛在生態風險因子為 As，潛在生態風險因子大小順序為 As＞Hg＞Cd＞Cu＞Cr＞Pb＞Zn。
대회안시모랄급전매장토양중13개채양점중전형중금속 Cr、Pb、As、Hg、Cd、Cu、Zn 적함량진행료조사，채용단인자오염지수、종합오염지수급 Hakanson잠재생태풍험지수법평개료토양중전형중금속대기소재배경적오염정도，대주위배경조성적잠재생태풍험영향。결과표명，연구구역내중금속함량균미초과《토양배경질량표준》（GB 15618-1995）이급표준。주요적잠재생태풍험인자위 As，잠재생태풍험인자대소순서위 As＞Hg＞Cd＞Cu＞Cr＞Pb＞Zn。
The situation and distribution of heavy metal pollution were investigated in the soil of the Municipal landfill in Huaian, Through analyzing the contents of the typical heavy metal pollutants (Cr,Pb,As,Hg,Cd,Cu,Zn)in the soil of 13 sample sites.The potential influences around environment involving the heavy metals were evaluated by the ecological risk index of Hakason ecological risk,single factor contamination index and comprehensive contamination index.The results showed that none of heavy metal in the studied region had overrun the Grade II of national Environmental Quality Standard for Soil (GB 15618 -95).The major factor of potential ecological risk was As,and the order of the potential ecological risks was As>Hg>Cd>Cu>Cr>Pb>Zn.
