Monitoring of carcinogenic PAHs in air under mild–warm ambient temperatures: relative importance of vapour- and particulate-phase analyses in assessing exposure and risk

Seasonal Abundance of Particle-Phase Organic Pollutants in an Urban/Industrial Atmosphere

“…At Statte, a higher percentage of PAHs were found in PUF extracts, which probably relates to the lower atmospheric concentrations. Higher loss rate constants with decreasing atmospheric concentrations (and vice versa) have been reported (Turpin et al 2000;Menichini and Monfredini 2003). Table 3 also shows the average concentrations of the methyl-PAHs and of dimethyl-PAHs associated with particulate matter at the three sampling sites in winter and in summer.…”

“…In contrast, fluorene, phenanthrene, and anthracene were almost totally found in PUF extracts, both at Tamburi and Statte. PUF extracts contain both volatile substances present in atmosphere as vapor phase and compounds volatilized from filters during collection because of the high air flow rate (Turpin et al 2000;Menichini and Monfredini 2003). Fluoranthene and pyrene were equally partitioned between the filter and the PUF cartridge at Tamburi.…”

Polycyclic aromatic hydrocarbons and their oxygenated derivatives in the urban atmosphere of Athens

“…The % homologue fraction in particulate form listed in Table 4 was also determined for Rome [54], Marseilles [55], Chicago [56] and Birmingham [57] Chrysene appeared to be more equally divided between the two phases by in March with 34% in particulate phase than in August with only 7.9% in particulate phase. As far as three-and most fourring PAHs, found predominantly in the gas phase, are concerned, our results appear to underestimate their concentrations in comparison to the measured ones in the other studies.…”

Levels and patterns of polycyclic aromatic hydrocarbons (PAHs) in soils after forest fires in South Korea

“…Some PAHs are considered carcinogenic compounds and harmful to humans (Menichini and Monfredini 2003). PAHs are mainly introduced into the atmosphere by anthropogenic activities like the incomplete combustion of fossil fuels, and they can undergo air dispersion, gas/particle partitioning, and long-range atmospheric transport (LRAT) (Choi et al 2007;Ding et al 2007;Su et al 2006).…”
