| 中文摘要: |
| 对连云港市商业区路边沉积物中Pb和Cu的含量及污染程度进行了调查。结果表明, 连云港市商业区路边沉积物中Pb的算术平均值为97.24 mg/kg, 是我国A层土壤算术平均值的3.7倍, 沉积物中Cu 的算术平均值为49.99 mg/kg, 是我国A层土壤算术平均值的2.24倍; 沉积物中Cu含量分布变异性比Pb含量高。地累积指数的评价结果表明, 沉积物中Pb比Cu污染严重。 |

| Pollutioninvestigation and evaluation of Pb、Cuin sediment near urban roads was donein Lianyungang. T hearithmetic mean of Pb was 97.24 mg/kg, was 3.7timesof A kind soil s arithmetic mean. For Cu, was49.99 mg/kg, 2.24 times. The concentration distribution variation of Cu wasgreater than Pb,andindicatedthatthepollution ofPb washeavierthan Cu. |
