  • 摘要: 采集了3个北京市郊发展新区(昌平区、大兴区、房山区)共计20个不同类型表层农业土壤样品,通过微波萃取和高效液相色谱分析其中多环芳烃(PAHs)含量.结果显示,研究区表层土壤已受到不同程度的污染,16种优先控制的多环芳烃总含量为1.20—3.35 μg·g-1,表层土壤中的多环芳烃主要源于燃烧源,且受燃汽油型汽车尾气的影响更显著.
    Abstract: The concentrations of polycyclic aromatic hydrocarbons (16 USA EPA priority PAHs) in the 20 collected soil samples in three urbanizing areas in the suburb of Beijing were determined using microwave assisted extraction and liquid chromatography. The results showed that the soils of the selected areas have been contaminated with PAHs in different levels. The concentrations of sixteen prior pollutants PAHs ranged from 1.20 μg·g-1 to 3.35 μg·g-1 in the samples. The PAHs in agriculture soils in Beijing suburbs was mainly from the pyrogenic source, which contributed dominantly by emissions from vehicle exhaust.
