The most prevalent pollutant, polycyclic aromatic hydrocarbons (PAHs) is now plenteously distributed in the global atmosphere. We recently quantified 36 polycyclic aromatic hydrocarbons (PAHs) associated with aerosols (particulate matter: PM) in five Asian cities: Tokyo (Japan), Beijing (China), Kolkata (India), Hanoi (Vietnam), and Kuala Lumpur (Malaysia). Average atmospheric PAH concentrations (∑12 PAHs-ng m -3 ) increased in the order of Kuala Lumpur (2.99) ≈ Tokyo (3.95) < Hanoi (7.99) << Kolkata (63.5) << Beijing (142.8). The most abundant PAHs in PM samples in these cities were chrysene, benz [a]anthracene, benzofluoranthenes, benzo[a]pyrene, and benzo[e]pyrene. We used the PAH compositions, especially the relative abundances of alkylated PAHs, and hopanes to determine vehicle exhaust-derived PAHs, and levoglucosan as a tracer for biomass burning, especially from wood combustion. Vehicle exhaust contributed to atmospheric PAHs in all cities, indicated by higher ratios of (C 30 17α)/total PAHs and MPAHs/PAHs than coal and wood combustion products. Coal combustion contributed also in winter aerosols in Beijing, indicated by higher abundance of β isomers i.e., 17β21β (H)-C 30 hopane (C 30 17β) and 17β21β (H)-C 29 hopane (C 29 17β) signifying mass use of coal for heating. The ratio of levoglucosan/PAHs was high in Kuala Lumpur and Hanoi, suggesting greater inputs of PAHs from biomass burning there.

Polycyclic aromatic hydrocarbons: levels and phase distributions in preschool microenvironment

This work aims to characterize levels and phase distribution of polycyclic aromatic hydrocarbons (PAHs) in indoor air of preschool environment and to assess the impact of outdoor PAH emissions to indoor environment. Gaseous and particulate (PM 1 and PM 2.5 ) PAHs (16 USEPA priority pollutants, plus dibenzo [a,l] This study fills a gap providing information on levels and phase distribution (gas, and PM 1 and PM 2.5 -bound) of polycyclic aromatic hydrocarbon (PAHs) in preschool educational settings. Despite the current concerns about regulations of indoor pollutants, there is lack of studies on indoor and outdoor PAHs in education settings; in addition, no study reported information about PAHs in the finest fractions of particulates (such as PM 1 ) in schools or preschools. The high proportion of PAHs detected in the gas phase clearly demonstrates that adequate assessment of PAHs exposure requires consideration of the gaseous compounds, which are commonly neglected.
