摘要
通过对安徽省沿淮淮北地区菜地土壤Pb、Cd、Cr、Hg含量分析测定,用内梅罗综合指数法评价了该地区菜地土壤的环境质量,结果表明:皖北地区菜地土壤Pb、Cd、Cr、Hg平均含量为22.5、0.247、63.2、0.040mg/kg,综合污染指数平均为0.64,皖北地区菜地土壤整体环境质量良好,少数蔬菜种植时间较长的日光温室土壤受到重金属污染,主要无机污染物是镉和汞。菜地土壤镉和汞的含量与土壤全磷、有效磷含量和菜地种植时间呈极显著相关。
The contents of heavy metal （Pb, Cd, Cr, Hg） in the vegetable soils collected from the main vegetable production areas in north of Anhui province were examined and analyzed to evaluate the vegetable soils status of heavy metal contamination. The evaluation of environmental quality of the vegetable soils was carried out by using the Nemerow index method. The results showed that the mean contents of Pb, Cd, Cr, Hg of the vegetable soils in of north Anhui were 22.5, 0.247, 63.2, 0.040 mg/kg and the mean integrated heavy metal pollution index of the vegetable soils was 0.64. The vegetable soils were good in quality on the whole. Some of the vegetable soils were polluted with heavy metals, Cd and Hg were the major pollution contributors. The contents of Cd and Hg were significantly correlated with soil total P,available P and the time of plating vegetables.
