临沂市区公路沿线土壤重金属污染分析

以临沂市区公路沿线土壤的重金属为研究对象,采集了0⁵cm和205cm和20²5cm处的表层土壤,采用电感耦合等离子原子发射光谱仪测定其中的Cd、Cu、Pb和Zn 4种重金属的含量,以查明当前公路两侧土壤受交通工具引起的重金属污染情况.研究结果表明,沿公路线的土壤中存在较严重的污染,主要是Pb和Cd出现中度乃至重度污染,同时也说明公路交通也会对其沿线土壤重金属污染产生较大影响.

Pollution A nalysisofH eavy M etalsin Soilalong the R oadsin Linyi

The heavy metals in the soil along the roads of Linyi were taken into consideration for their pollution from traffic vehicles. And the soil samples under the surface of 0-5 cm and 20-25 cm were collected. The heavy metals investigated include Cd, Cu, Pb and Zn, which were determined by inductively coupled plasma optical emission spectrograph. The results showed that pollution of heavy metals in the soil along the roads had been emerged, mainly Pb and Cd in moderate and severe pollution he road transportation has made an impact on the pollution of heavy metals in the soil along the roads.
