Atmospheric polycyclic aromatic hydrocarbons (PAHs) in Asia: A review from 1999 to 2004

Inhalation and dermal exposure to atmospheric polycyclic aromatic hydrocarbons and associated carcinogenic risks in a relatively small city

“…This is because the gaseous phase PAH compounds have lower molecular weights and TEF values than the particle phase PAH compounds. The BaP eq concentrations measured in this study are similar to those measured in Kocaeli, Turkey (Gaga et al, 2012), are in the range of those measured in Asian countries (Chang et al, 2006), lower than those measured at road intersections in Tianjin, China (Hu et al, 2007) and at a highway toll station in Taiwan (Tsai et al, 2004), higher than those measured in in Zaragoza, Spain (Callen et al, 2007) and in the UK (Delgado-Saborit et al, 2011). Some of the PAHs have been classified as Group 1, 2A, and 2B carcinogens by International Agency for Research on Cancer (IARC) based on various levels of animal and human studies.…”

Study of the polycyclic aromatic hydrocarbons content in gas released from burning mine waste dump

“…Since currently the literature data available on emission of organic pollutants released to the atmosphere from burning waste dumps is limited, the concentrations of gas-phase PAHs in collected samples were compared also to the results of other studies, conducted for urban areas with the use of similar sampling methods (polyurethane foam samplers). The average total PAHs concentration determined in this study was much higher than the values reported for Seoul, Korea (63.03 ng/m 3 ) [21] and for urban and industrial sites of southern and central Taiwan: 535.2-1123.7 ng/m 3 [5] and 652.1-950.7 ng/m 3 [22]. The average PAHs concentrations reported by [17] were also lower than the values reported in the study (2.14-167 ng/m 3 ).…”

Polycyclic aromatic hydrocarbons (PAHs) in atmospheric PM2.5 and PM10 at a coal-based industrial city: Implication for PAH control at industrial agglomeration regions, China

“…BaPeq concentration for each PAHs is calculated by multiplying its concentration with the corresponding toxic equivalent factor (TEF) which represents the relative carcinogenic potency of the corresponding PAHs suggested by Nisbet and LaGoy's TEFs which have been widely used (Nielsen et al, 1996;Chang et al, 2006;Wang et al, 2006;Hong et al, 2007;Akyüz and Çabuk, 2008). The carcinogenic potency of total PAHs can be assessed by the sum of the BaPeq concentrations of each PAHs.…”
