    摘要:

    通过室外采样和室内分析,对阜阳市颍州区城郊菜地土壤Pb、Cd、Ni、Cu、Cr、Zn等六种重金属的含量特征进行了研究,并利用单因子污染指数法、内梅罗综合污染指数法对各种重金属的污染状况进行了评价。研究表明,研究区域菜地土壤中各种重金属含量的平均值均符合国家土壤环境质量标准要求,其中Pb、Ni、Zn含量平均值超出安徽省土壤背景值,其他重金属的平均值均未超过安徽省土壤重金属背景值。单因子污染指数法和内梅罗综合污染指数法评价表明,研究区域未受到污染,适合进行无公害生产。

    Abstract:

    By means of field sampling and laboratory analysis, the content distribution characteristics of Pb, Cd, Ni,Cu, Cr and Zn in suburban vegetable soil of Yingzhou District of Fuyang City were analyzed. Assessment of heavymetal pollution was conducted using single factor pollution index, Nemerow Comprehensive Pollution Index. The re-sults showed that the average mass fraction of Heavy Metals met the requirements of state soil environment qualitystandard. The average mass fraction of Pb, Ni and Zn were above the background values of Anhui Province. The av-erage mass fraction of other heavy metals did not exceed the average values of Anhui Province. The results of theevaluations from single factor pollution index, Nemerow comprehensive pollution index discovered that research dis-tricts were not polluted and the soil was suitable for production of nuisanceless agricultural products.
