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97.24mg/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49.99mg/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。
Pollution investigation and evaluation of Pb?Cu in sediment near urban roads was done in Lianyungang. The arithmetic mean of Pb was 97.24 mg/kg, was 3.7 times of A kind soil's arithmetic mean. For Cu, was 49.99 mg/kg, 2.24 times. The concentration distribution variation of Cu was greater than Pb, and indicated that the pollution of Pb was heavier than Cu.
