Atmospheric polycyclic aromatic hydrocarbons observed over the North Pacific Ocean and the Arctic area: Spatial distribution and source identification

Polycyclic aromatic hydrocarbons (PAHs) in continental shelf sediment of China: Implications for anthropogenic influences on coastal marine environment

“…This potentially implicated the role of black carbon (Oen et al, 2006;Sánchez-García et al, 2010) as an important factor governing environmental distribution of PAHs. The extent of photodegradation can be diagnosed using the ratios of BaA/Chr and BaP/BeP, as BaA and BaP can be more easily photo-degraded than Chr and BeP (Ding et al, 2007). The lower values of BaA/Chr and BaP/BeP (Fig.…”

Polycyclic aromatic hydrocarbons in PM2.5 in Guangzhou, southern China: Spatiotemporal patterns and emission sources

“…IcdP to BghiP, were jointly used. IcdP to BghiP ratio was selected because the two PAHs are photolytically degraded at comparable rates and therefore their ratios retain the characteristics of emission sources [28,29]. Also plotted in Fig.…”

Atmospheric polycyclic aromatic hydrocarbons in rural and urban areas of northern China

“…However, atmospheric movement may transport PAHs from sources to remote areas. Reports at Arctic and oceans have proved that some pristine areas far away from anthropogenic activities can be influenced by PAHs pollution through air mass movement (Ding et al, 2007).…”
