“…BaA, BbkF, BaP and DahA were identified as the major atmospheric contributors, representing > 80% of the total BaP eq . The BaP contribution was lower than the evaluation in Agra, India (Masih et al, 2012), which can be attributed to the spatial variation and the difference between AAS and PAS.…”

“…Compared with the congener profiles in cities (Liu et al, 2007;Bohlin et al, 2008) and background sites (Halse et al, 2011), the Indian air was characterized by a relatively high proportion of HMW PAHs. An enrichment of HMW PAHs in the air was also recorded at a rural site in Chennai (Masih et al, 2012). Although there is a discrepancy in congener profiles between the PAS and AAS technique (Bohlin et al, 2009), this report still confirms that PUFePAS captures a part of particle-associated HMW PAHs.…”

“…In India, vehicular traffic and industrial operations are mainly responsible for the atmospheric PAH pollution in the metropolitan areas. Traditional biomass resources are still used to meet an overwhelming proportion of the rural energy demand, possibly explaining the measured PAH concentration comparable to urban regions in rural site (Masih et al, 2012). The two types of sources exhibit specific isomeric ratios if the relative proportions of the species in question are assumed to be conserved between each emission source and the downwind point of measurement (Galarneau, 2008).…”

“…Zhang and Tao (2009) estimated that the annual PAH emissions from India was 90 Gg y -1 , constituting 23.6% of the total global emissions. Traditional biomass resources are still used to meet the overwhelming proportion of India's energy demand (Masih et al, 2012), which could lead to a significant amount of PAH release. Some reports have indicated that atmospheric PAH levels in Indian cities are higher than in other urban sites around the world (Sharma et al, 2007;Singh et al, 2011).…”

“…This approach is justified by the widespread belief that the vapor fraction of the most harmful PAHs with 5-6 aromatic rings is negligible (Liu et al, 2001a;Lu and Chen, 2008;Pandey et al, 2011;Slezakova et al, 2011;Szulejko et al, 2014). However, it has been observed that, even for benzo(a)pyrene, the vapor fraction can sometimes constitute a significant amount of the total concentration (Possanzini et al, 2004;Temime-Roussel et al, 2004;Masih et al, 2012;DelgadoSaborit et al, 2014). Additionally, a significant amount of pollutants could be desorbed from the aerosol particles collected on the filter during the sampling, McMurry 1991, Delgado-Saborit et al, 2014).…”

The sampling of polycyclic aromatic hydrocarbons (PAHs) in the atmosphere is often performed on filters, which retain only aerosol particles, disregarding the vapor fraction; after the filter, an adsorbent (e.g., polyurethane foam, PUF, or styrene/divinylbenzene, XAD) is sometimes used for sampling vapors not retained from the filter. However, the use of an adsorbent may lead to many disadvantages: contaminations, analysis time and costs, and size problems when developing automated or personal samplers. In this work, a functionalized glass fiber filter for the simultaneous sampling of aerosol particles and vapor fraction is presented for the sampling of PAHs in air. A low sampling efficiency was observed for 3 ring PAHs, but all carcinogenic PAHs (according to IARC) were totally retained on functionalized filters. On the other hand, a comparison with normal filter sampling was performed, and results obtained confirm that > 10% of benzo(a)pyrene can be lost from normal filters. Together with size reduction, another advantage of the functionalized filter is an enhancement in the extraction and purification recovery.

Biomass burning is a significant anthropogenic source of air pollution, including the preharvest burning of sugar cane. These burn events result in atmospheric emissions, including semivolatile organic compounds, that may have adverse impacts on air quality and human health on a local, regional, and even a global scale. Gaseous and particulate polycyclic aromatic hydrocarbon (PAH) emissions from various sugar cane burn events in the province of Kwa‐Zulu Natal in South Africa were simultaneously sampled using a portable denuder sampling technology, consisting of a quartz fiber filter sandwiched between two polydimethylsiloxane multichannel traps. Total gas and particle phase PAH concentrations ranged from 0.05 to 9.85 µg m–3 per individual burn event, and nine PAHs were quantified. Over 85% of all PAHs were found to exist in the gas phase, with smaller two‐ and three‐ring PAHs, primarily naphthalene, 1‐methyl naphthalene, and acenaphthylene, being the most dominant and causing the majority of variance between the burn sites. The PAH profiles differed between the different burn events at different sites, emphasizing the significant influence that the crop variety, prevailing weather conditions, and geographical location has on the type and number of pollutants emitted. The potential carcinogenicity of the PAH exposure was estimated based on toxic equivalency factors that showed varying risk potentials per burn event, with the highest value of 5.97 ng m–3.
