摘要：
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.
