“…This value is in the same range as the ratios reported for diesel vehicles 47,48 and also for soil and paved road dust. 47 The ratios B[ghi]Pe/B[a]Py, calculated as 2.61 and 2.15, for TSP and PM10, respectively, may be compatible with paved road dust and some urban samples. Some reported data for gasoline and diesel vehicles are also in this range.…”

“…In 2004, Manoli et al 47 published the PAHs profiles for several urban, industrial and geological sources, in particular diesel fueled buses, paved road dust and soil dust absorbed to PM10 samples. In general, diagnostic ratios for ambient urban samples were similar to those obtained for paved road and soil dust.…”

“…Many of these data are shown in Table 2. Urban samples were those determined by Mantis et al 48 in an Aristotelous street, in downtown Athens, with dense vehicular traffic and commercial activities, and by Manoli et al 47 in the city center of Thessalonike, Greece, an area with high commercial activities and traffic density.…”

. The same most abundant compounds were obtained in PM10 samples and a total mean mass of 8.99 ng m -3 was determined. Diagnostic ratios were calculated and vehicular emissions were determined as the potential sources for PAHs in particulate matter. The contribution of both light duty and diesel engines is significant, but the cluster and factorial analysis failed to classify clearly in gasoline or diesel emissions.

It has been proposed that extensive wildfires occurred after the Cretaceous-Tertiary (K-T) impact event. An abundance of soot and pyrosynthetic polycyclic aromatic hydrocarbons (pPAHs) in marine K-T boundary impact rocks (BIRs) have been considered support for this hypothesis. However, nonmarine K-T BIRs, from across North America, contain only rare occurrences of charcoal yet abundant noncharred plant remains. pPAHs and soot can be formed from a variety of sources, including partial combustion of vegetation and hydrocarbons whereby modern pPAH signatures are traceable to their source. We present results from multiple nonmarine K-T boundary sites from North America and reveal that the K-T BIRs have a pPAH signature consistent with the combustion of hydrocarbons and not living plant biomass, providing further evidence against K-T wildfires and compelling evidence that a significant volume of hydrocarbons was combusted during the K-T impact event.

“…The concentration ratios of individual PAHs in ambient samples and source emissions are frequently employed as diagnostic tools to identify their origin in ambient air [28,29]. Recently, in Northern China emission sources of particle-phase PAHs were identified using a diagnostic plot of FLN/(FLN þ PY) versus IcdP/(IcdP þ BghiP) [30].…”

Ambient air polycyclic aromatic hydrocarbon (PAH) samples were collected at a suburban (n ¼ 63) and at an urban site (n ¼ 14) in Izmir, Turkey. Average gas-phase total PAH ( P 14 PAH) concentrations were 23.5 ng m À3 for suburban and 109.7 ng m À3 for urban sites while average particle-phase total PAH concentrations were 12.3 and 34.5 ng m À3 for suburban and urban sites, respectively. Higher ambient PAH concentrations were measured in the gas-phase and P 14 PAH concentrations were dominated by lower molecular weight PAHs. Multiple linear regression analysis indicated that the meteorological parameters were effective on ambient PAH concentrations. Emission sources of particle-phase PAHs were investigated using a diagnostic plot of fluorene (FLN)/ (fluorine þ pyrene; PY) versus indeno[1,2,3-cd]PY/(indeno[1,2,3-cd]PY þ benzo[g,h,i]perylene) and several diagnostic ratios. These approaches have indicated that traffic emissions (petroleum combustion) were the dominant PAH sources at both sites for summer and winter seasons. Experimental gas-particle partition coefficients (K P ) were compared to the predictions of octanol-air (K OA ) and soot-air (K SA ) partition coefficient models. The correlations between experimental and modeled K P values were significant (r 2 ¼ 0.79 and 0.94 for suburban and urban sites, respectively, p < 0.01). Octanol-based absorptive partitioning model predicted lower partition coefficients especially for relatively volatile PAHs. However, overall there was a relatively good agreement between the measured K P and soot-based model predictions.
