| 摘 要： | 为考察包头城区土壤重金属污染现状,在包头城区范围内布设88个采样点,测定土壤中Cd、Pb、Cu、Zn、Cr的含量,并分析其空间分布特征及相关关系,评价其污染状况。结果表明:人类活动强烈干扰了包头城区土壤,Cd、Pb、Cu、Zn普遍超标,且均在冶金工业区出现极大值;城区土壤重金属呈现由工业生产、交通运输及燃煤活动共同作用的复合污染态势;5种重金属综合评价结果为重度污染,其中Cd的单因子指数均值达到7.05,已对居民健康造成威胁和危害。

| Abstract: | In order to investigate the pollution status of heavy metals in the urban areas of Baotou,among the 88 soil samples in the urban areas of Baotou,the paper determined the content of heavy metals Cd,Pb,Cu,Zn,Cr in soil,analyzed the charactcristic of the spatial distribution and relativity analysis of heavy metals,and evaluated heavy metals pollution.The results showed that the soil was serious polluted by human activities.Cd,Pb,Cu,Zn were above the Inner Mongolia soil background values and soils from the metallurgical industry had the most serious heavy metal contamination;urban soil heavy metals presented combination of compound pollution situation by industrial production transportation and coal activity.Comprehensive evaluation of the results showed that five heavy metals were severe pollution,the single factor index of Cd was 7.05 and had been a threat to residents' health. |
