| 摘 要： | 采样分析了广西环江县大环江河下游沿岸受重金属污染的4块农田土壤及农作物可食用部分重金属含量,并进行了污染评价。结果表明,4块受污染农田土壤重金属污染级别均为轻污染,受污染农田土壤上种植的油麦菜、茼蒿、生菜、小白菜、稻米等农作物可食用部分为重污染,污染水平远远超过国家食品卫生限值标准。建议在未经改良的情况下,不宜在重金属污染的土壤上种植此类农作物。 |

| Abstract: | The content of heavy metals in the four farmland soil and crops was analyzed and their pollutions was evaluated.The results indicate that the heavy metal pollution distinction of the four farmland soil is all light,the edible plant parts of naked oat,chrysanthemum coronarium,lettuce,cabbage,rice is serious,the pollution level far more exceed the tolerance limit in foods of nation food security standard.It is proposed that this kind of crops should not be grown on heavy metal pollution soil before it has been mended. |
