“…14 PAH concentrations in soil reported by Zhang et al [39] for the urban area in Hong Kong, by Nadal et al [18] for the industrial and unpolluted areas in Spain, by Motelay-Massei et al [40] for industrial, urban and remote areas in France, and by Cousins and Jones [15] for a rural area in the UK were higher than the values measured in this study while the con- Table 3 Soil concentrations (ng g −1 dry wt) and air/soil net gas exchange fluxes (ng m −2 day −1 ) of PAHs at suburban site (average ± SD). centrations reported by Zhang et al [39] for a rural area in Hong Kong were lower.…”

“…Sixty-three ambient air and 53 dry deposition samples were collected. Another two additional sampling programs were conducted between March 17-24, 2004 (winter) and July [15][16][17][18][19][20][21][22]2004 (summer) at urban site. Successive 7 samples (ambient air and dry deposition) were collected for each sampling period.…”

“…Method 2540-E has been commonly used because it offers an approximation of the amount of organic matter present in the solid fraction [17,18]. The injector, ion source, and quadrupole temperatures were 295, 300, and 180 • C, respectively.…”

a b s t r a c tAmbient air and dry deposition samples were collected at suburban and urban sites in Izmir, Turkey. Atmospheric total (particle + gas) 14 PAHs concentrations were 36 ± 39 and 144 ± 163 ng m −3 for suburban and urban sites, respectively. Phenanthrene was the most abundant compound at all sites, and all samples were dominated by low molecular weight PAHs. Average particulate 14 PAH dry deposition fluxes were 8160 ± 5024 and 4286 ± 2782 ng m −2 day −1 and overall average particulate dry deposition velocities were 1.5 ± 2.4 and 1.0 ± 2.3 cm s −1 for suburban and urban sites, respectively. Soil samples were collected at suburban site. Average soil concentration for 14 PAH was 55.9 ± 14.4 ng g −1 dry weight. Calculated gas-phase air-soil exchange fluxes indicated that fluorene, phenanthrene, anthracene, and carbazole were deposited to soil in winter while they were volatilized in summer. Other compounds (fluoranthene-benzo[g,h,i]perylene) were deposited to soil in both periods. Annual average fluxes of PAHs representing soil to air (i.e., gas volatilization) and air to soil transfer (i.e., gas absorption, dry deposition, and wet deposition) processes were also compared. All processes were comparable for 14 PAHs however their input was dominated by gas absorption. Gas absorption dominated for lower molecular weight PAHs, however dry deposition dominated for higher molecular weight PAHs. The results have suggested that for fluorene, soil and air may be approaching a steady state condition. For the remaining compounds, there was a net accumulation into the soil.

“…They are formed as incomplete combustion products of coal, oil and gas, garbage, or other organic substances like tobacco or charbroiled meat (Nadal et al, 2004). Apart from the combustion source, another common anthropogenic source of PAHs is the accidental spillage of fossil fuels, including crude oils and refined oil products (e.g., petrol).…”

“…The development and establishment of a toxicity equivalency factors (TEFs) are used in the assessment of mixtures containing PAHs. The TEFs were used to quantify the carcinogenic potential of other PAHs relative to BaP and to estimate benzo[a]pyrene-equivalent concentration (BaPeq) (Nadal et al, 2004). The list of TEFs (Table 3) (Table 3).…”

As a developing country, the economic and population growth rates in Ghana over the past few years have seen tremendous increase. The growing rate of industrialization is gradually leading to contamination and deterioration of the environment and pollution is likely to reach disturbing levels. Surface soil samples were collected randomly from 36 communities in the Kumasi metropolis, Ghana, to determine the concentrations, distribution, sources and toxic potential of emission of polycyclic aromatic hydrocarbons (PAHs) since no such comprehensive study has been conducted. The mean concentration of total PAHs in the surface soils in each community ranged from 14.78 at Ahinsan to 2084 ng/g dry weight at Adum with an average of 442.5 ± 527.2 ng/g dry weight. Diagnostic ratios and chemical mass balance models of the results showed that PAHs in surface soil samples from the study area were mainly from fuel combustion.Carcinogenic potency of PAHs load from the city centre was approximately 150 times higher as compared to a pristine site, Kwame Nkrumah University of Science and Technology's Botanical Garden. BaP, a human carcinogen, contributed 70% of the total PAHs toxicity level from the city centre of Kumasi.
