Abstract

Based on construction of dust particles extraction of polycyclic aromatic hydrocarbons in the optimized analysis, to determine the optimal experimental conditions of ultrasonic extraction of polycyclic aromatic hydrocarbons; Determination of polycyclic aromatic hydrocarbons are normalized concentration analysis, Phenanthrene (PhA) was the highest, accounting for 29.1% of the total PAHs, followed by Naphthalene (NaP) 18.9%, Benzo[b] fluorathene (BbF) 13.1%, Pyrene (Pyr) 8.2%; building the dust PM2.5 fine particles of polycyclic aromatic hydrocarbons the source component spectrum, provide analysis data for the control and management of pollution sources.
