凉山州土壤和部分果蔬Cu、Cd含量关系及污染评价

检测了凉山州果蔬产区26个采样点的土壤和对应果蔬的Cd、Cu的含量,结果表明,土壤Cd含量属于内梅罗污染指数评价指标的尚清洁(警戒)等级,Cu含量属于内梅罗污染指数评价指标的中度污染等级;果蔬Cd含量属于内梅罗污染指数评价指标的轻度污染等级,Cu含量属于内梅罗污染指数评价指标的清洁(安全)等级;土壤与果蔬Cd、Cu含量关系不存在明显的正相关。

The Cu, Cd Contents Relations between Soil and Some Fruit and Pollution Assessment in Liangshan Prefecture
