| 摘 要： | 以沈大高速公路为研究对象,采集高速公路旁种植的粮食和水果样品进行了重金属铅和镉的测定。结果表明:沈大高速公路旁粮食和水果已受到不同程度的铅镉污染,不同作物呈现不同的重金属污染特征。通过对不同处理方式处理后的水果中重金属的分析表明,土壤吸收和大气尘降是农作物中重金属的主要来源。公路交通的铅镉污染仍然是影响路旁农产品质量安全的重要因子之一。

| Abstract: | Pb and Cd contents in grains and fruits at both sides of Shenyang-Dalian expressway were determined.The results show that the grains and fruits are polluted by Pb and Cd.The different crops are polluted by different heavy metals.According to the heavy metal contents in the fruits,soil absorption and atmospheric dust become the main sources of heavy metal pollution in crops.Pb and Cd pollutions are still one of the main environmental factors influencing the safety of agricultural products. |

| Keywords: | Grains Fruits Heavy mental pollution Shenyang-Dalian expressway |
