机动车排放颗粒物中多环芳烃化合物的研究

Study on Polycyclic Aromatic Hydrocarbons (PAHs) in Particulate Matters from Vehicle Emission

    摘要
  • 摘要: 利用1999年7月谭裕沟隧道和1999年9月梧桐山隧道TSP,PM10和PM2.5中PAHs的分析结果,研究了机动车排放PAHs的污染状况和污染特征.结果表明,机动车行驶排放出的大量PAHs主要存在于粒径较小的粒子中,苯并a芘严重超标.

     

    Abstract: On the basis of analytical results of PAHs in TSP,PM 10 and PM 2.5 obtained from experiments around Tanyugou highway tunnel and Wutongshan highway tunnel,we studied pollution status and pollution characteristics of PAHs from vehicle emission.Results show that large amount of PAHs emitted from vehicles mainly existed in fine particles and Benzo(a)pyrene exceeded the standards seriously.
