摘要
检测了凉山州多种农产品和对应土壤的Cd、Cu的含量,内梅罗污染指数评价表明,凉山州土壤Cd、Cu存在不同程度的污染;除苦荞外,各类农产品Cd含量受土壤中Cd含量影响明显,各类农产品不存在Cu含量污染;土壤与各类农产品Cd、Cu含量关系不存在明显的正相关。
The Cd,Cu content of soil and agricultural products in Liangshan was tested in the experiment.Results showed that: assessed by Nemerow pollution index,the soil in Liangshan had degrees of the Cd,Cu pollution.The Cd content of agricultural products in addition to buckwheat was influenced significantly by the Cd content of soil,but the Cu content of agricultural products did not meet the pollution level.The relationship of the Cd,Cu content between the soil and agricultural products in Liangshan did not exist a significant positive correlation.
