Characteristics of Black Carbon Particle-Bound Polycyclic Aromatic Hydrocarbons in Two Sites of Nanjing and Shanghai, China

Abstract: Airborne polycyclic aromatic hydrocarbons (PAHs) are of great concern to human health due to their potential high toxicity. Understanding the characteristics and sources of PAHs, as well as the governing factors, is therefore critical. PAHs and refractory black carbon (rBC) are both from combustion sources. This work, for the first time, investigated exclusively the rBC-bound PAH properties by using a laser-only Aerodyne soot-particle aerosol mass spectrometer (SP-AMS). This technique offers highly time-resolv… Show more

“…It has been proved that BC can play a key role in aerosol-planetary boundary layer (PBL) interactions and thereby affect air quality in high BC emission regions, like eastern China [9,10]. BC can also absorb some volatile toxic substances (such as polycyclic aromatic hydrocarbons PAHs) [11,12] and provide them with oxidation reaction sites to form more toxic PAHs oxidation derivatives [13,14]. On the other hand, the particle size distribution of BC generally ranges from 0.01 to 1.0 µm, which are more likely to be deposited in the human body and cause health effects to the public [15][16][17].…”
