摘要
对研究区路旁300 m范围内的土样中重金属Pb、Cd、Cr、Cu、Zn的含量采用原子吸收光谱法进行了测定。结果表明,土壤中重金属Pb、Cd、Cr、Cu、Zn含量平均值分别为33.65、3.82、46.62、17.02、235.63 mg/kg,分别为当地土壤背景值的1.15、1.16、1.69、1.17、2.12倍。重金属Pb、Cd、Cr、Cu处于轻度污染状态,重金属Zn已形成中度污染。
The content of heavy metal lead in sample of soils 300 meters off the roadside was determined by atomic absorption spectrophotometry. The average content of Pb, Cd, Cr, Cu and Zn in soils alone the road was 33.65, 3.82, 46.62, 17.02,235.63 mg/kg respectively, which was 1.15,1.16,1.69,1.17 and 2.12 times of the soil background values of the study area. Pb, Cd, Cr and Cu were all at light pollution level, Zn was at middle pollution level.
