| 摘 要： | 用HNO3-HF-HClO4消解土壤样品,用原子吸收光谱法对山东范县等五个地方的公路沿线土壤样品中重金属Pb、Cr、Zn、Fe、Cd、Ni的含量进行了分析测定,并对重金属元素在土壤中的存在方式进行了研究,反映出公路沿线土壤中重金属元素的积累情况。由测定结果表明,该地区土壤中铁含量较高,其余各重金属含量均很低,土壤基本没受污染。

| Abstract: | Five soil samples of counties along the line of highway in Shandong Province were dissolved with nitric acid-hydrofluoric acid-perchloric acid. Content of heavy metals including lead, chromium, zinc, iron, cadmium and nickel was analyzed and measured using atomic absorption spectroscopy to investigate the existing forms and accumulation of heavy metals in soil along the line of highway. Results showed that the content of iron was higher while the content of other heavy metals were all very low and soil was not polluted in general. |
