| 摘 要： | 采用高效液相色谱/质谱联用技术(HPLC/MS)检测了北京市石景山工业区和海淀居民生活区的大气颗粒物样品中的多环芳烃(PAHs),比较了北京市工业区和居民区大气飘尘中多环芳烃含量的差异以及不同季节对多环芳烃含量的影响.检测出PAHs类碳氢化合物共135种,分子质量大于300u的PAHs有55种,弥补了气相色谱/质谱(GC/MS)不能直接测定大分子量PAHs的不足,更为全面地反映了大气飘尘中PAHs的分布状况.

| Abstract: | The composition of polycyclic aromatic hydrocarbons (PAHs) in fly ash samples which were gathered from manufacturing district of Shijingshan district and residential quarters of Haidian district were analyzed using HPLC/MS technique. The differences of the contents of PAHs in fly ash samples from manufacturing district and residential quarters were compared. The changes of the contents of PAHs of different seasons were discussed. In this study, 135 PAHs including 55 large PAHs whose molecular weights are greater than 300u were detected in fly ash sample from manufacturing district. HPLC/MS offset the deficiency of GC/MS which can not determine large PAHs directly and can reflect the distribution of PAHs in fly ash more roundly. |
