Atmospheric polycyclic aromatic hydrocarbons (PAHs) from post-harvest biomass burning emissions in the Indo-Gangetic Plain: Isomer ratios and temporal trends

Diurnal Variability in Secondary Organic Aerosol Formation over the Indo-Gangetic Plain during Winter Using Online Measurement of Water-Soluble Organic Carbon

“…Enhanced SOA formation is reported during foggy days over the IGP (Kaul et al, 2011). The particulate chemical composition over the IGP is dominated by organic aerosols and, WSOC is a large component of the total OC (Rajput et al, 2011;Rastogi et al, 2014); however, understanding on WSOC (SOA) formation is meager. Online measurements of WSOC offer greater insights in understanding the processes forming SOA during different time of the day (Sullivan et al, 2004).…”

Vertical Distribution and Potential Risk of Particulate Polycyclic Aromatic Hydrocarbons in High Buildings of Bangkok, Thailand

“…It is worth stressing that PAHs have complicated emission sources and thus numerous studies focused on characterization of source profiles and source apportionment by using field measurement of particulate PAHs collected from network monitoring stations around the world (Okuda et al, 2002;Yang et al, 2002;Tsapakis and Stephanou, 2005;Pongpiachan, 2006;Wan et al, 2006;Vasconcellos et al, 2010;Oanh et al, 2011;Rajput et al, 2011;Riva et al, 2011). In spite of innumerable publications in the field regarding the diurnal and seasonal variation of PAHs, its vertical distribution in tropical aerosols are still unclear, in particular in Southeast Asian countries where air pollution is a daily concern.…”

Characterization of carbonaceous aerosols over the East China Sea: The impact of the East Asian continental outflow

“…The major factor influencing the OC/EC values observed in fall and winter could be continental pollutant outflow via transport of the air mass. In fall, crops including cotton, rice, and wheat are harvested, but their straw residues are discarded and burned (Gustafsson et al, 2009;Rajput et al, 2011). Burning of these crops emits high concentrations of organic compounds.…”
