摘要
为了研究长株潭地区公路两侧土壤中重金属污染特性,采用在芙蓉南路口布点采样的方式,通过原子吸收光谱法和分光光度法分析土壤中重金属(Pb,Zn,Cu,Cr,Ni)的相关性质.研究结果表明,土壤中严重污染的元素为Zn,Pb,Cu;轻度污染的元素为Cr和Ni;土壤重金属元素有效态占总量百分比的顺序为Pb>Zn>Cr>Cu>Ni.通过分析还发现,公路旁土壤中重金属污染物质的主要来源是机动车燃料和轮胎中所含微量重金属成分.
In order to research the heavy metal pollution in the soil along the highway of Changsha-Zhuzhou-Xiangtan area, the Hibiscus south crossroads stationing sampling are selected to analyze the related properties of heavy metal （Pb,Zn,Cu,Cr,Ni） in soil by atom- ic absorption spectrometry and spectrophotometry. The results show that serious pollution of the element are Zn and Pb,Cu, lightly polluted elements are Cr and Ni, heavy metals in the percentage of the tatal size of the order is Pb〉Cr〉 Zn〉Cu〉Ni. The analysis shows that the source of pollution was the heavy metals from the fuel of motor vehicles and trace heavy metals contained in tires.
