Characteristics of Polycyclic Aromatic Hydrocarbons (PAHs) in PM_(10) and PM_(2.5) and the Influence of Foggy Weather Conditions During the Winter in Nanjing
To study the distribution characteristics of polycyclic aromatic hydrocarbons (PAHs) in PM10 and PM2.5 and the influence of foggy weather conditions, aerosol samples were collected in foggy and sunny days in Nanjing,and the concentrations of 16 priority-controlled PAHs were analyzed by gas chromatography with mass selective detection (GC-MS).The results suggest that the total concentrations of 16 PAHs in PM10 and PM2.5 during foggy days are higher by 34.72 ng.m3 and 35.35 ng.m~(-3) respectively than those d...
