Abstract: 以浙东沿海某典型固废拆解区为研究区域,通过采集土壤、灌溉水、农作物以及大气干湿沉降样品进行分析测试,研究土壤Cd、Cu含量特征及其对农产品安全的影响。结果表明,研究区表层(0~20 cm)土壤已遭受较为严重的Cd、Cu污染,土壤Cd、Cu含量平均值分别为0.34和65.83 mg.kg-1。土壤中活性较高的水溶态、离子交换态和碳酸盐结合态Cd占Cd总量的比例达45.37%,说明其生物有效性和潜在危害性极大。大气干湿沉降、污水灌溉对土壤Cd、Cu的累积均有一定影响。农作物尤其是蔬菜Cd、Cu含量已有不同程度的累积甚至超标,食用的潜在危害性较大。相关分析表明,农作物Cd、Cu含量与土壤中Cd、Cu含量均呈显著正相关关系。
