“…Oxy-PAHs are emitted from primary sources or formed by atmospheric reactions between PAHs and atmospheric oxidants such as NOx and O 3 (Bandowe et al, 2014;Lee et al, 2018). Naphthalic anhydride (NAP-AN) and xanthone indicate the increased reactivity of PAHs adsorbed on particles exposed to atmospheric oxidants (O 3 , OH and NO 2 /O 3 mixture) (Ringuet et al, 2012), probably stimulated by photochemical activity leading to oxidation of PAHs.…”

“…Naphthalic anhydride (NAP-AN) and xanthone indicate the increased reactivity of PAHs adsorbed on particles exposed to atmospheric oxidants (O 3 , OH and NO 2 /O 3 mixture) (Ringuet et al, 2012), probably stimulated by photochemical activity leading to oxidation of PAHs. PCA analyses showed that the major sources of oxy-PAHs and PAHs are vehicle emissions and biomass burning (Lee et al, 2018) which can be taken to represent secondary organic aerosol (SOA) formed by photochemical reactions in the atmosphere.…”

“…Collection of ambient particulate matter (PM) at the Seoul metropolitan area and particle preparation was described in a previous study [51] which showed the detailed process for sampling of PM10 and extraction of organic matter from PM. Briefly, PM10 samples were collected at the roof of a public health building of Seoul National University in the Seoul metropolitan area.…”

“…Additionally, Chen et al [8] suggested that, with smaller particle size, PM 1 is more harmful than PM 2.5 . Despite this, ambient levels and distribution of quinones have been determined mainly in PM 10 [9][10][11] and total suspended particles [12,13], while few studies have addressed those in the gas phase and fine particles simultaneously [14][15][16].…”
