“…In winter period, contributions of phenanthrene, fluorene, fluoranthene, and pyrene in suburban and urban sites were 35%, 12%, 16%, and 11% and 26%, 8%, 22%, and 16% of 14 PAHs, respectively. These percentages were similar to the ones reported previously by Bozlaker et al [5], Gevao et al [32], and Odabasi et al [25]. The differences in contributions of individual PAHs to 14 PAHs between summer and winter may be due to the seasonal changes in PAH profiles (i.e., increasing residential heating in winter).…”

“…However, total 14 PAH concentrations measured at all sites in this study are significantly higher than those reported by Mandalakis et al [26] for urban Athens. The PAH levels measured at suburban site in this study are similar to those reported by Bozlaker et al [5] for an industrial site in Izmir, by Tsapakis and Stephanou [27] for urban Heraklion, by Ohura et al [28] for industrial sites in Fuji and Shimizu, and by Dachs et al [29] for urban/industrial Baltimore. The PAH levels at the urban site determined in this study are comparable to those reported by Possanzini et al [30] for downtown Rome and by Halsall et al [31] for urban sites in London and Manchester.…”

“…centrations reported by Zhang et al [39] for a rural area in Hong Kong were lower. Recently measured 14 PAH soil concentrations at Aliaga industrial region were generally significantly higher than those measured in the present study [5].…”

“…The decrease in deposition velocity with increasing molecular weight is supported by other experimental studies which have shown that a greater fraction of the higher molecular weight PAHs are associated with fine particles relative to the lower molecular weight compounds [4,36,37]. A similar decrease in deposition velocity with increasing molecular weight was previously reported for PAHs [4,5,[33][34][35]38]. Table 3 shows the individual PAH concentrations in soils taken from the suburban site.…”

“…Since the sampling point is relatively far from the local sources, this can be explained by the higher molecular weight compounds being deposited more easily than the lower molecular weight ones which are mainly in gaseous form and capable of long-range transport. Bozlaker et al [5] have recently reported that the PAH profile at an industrial site was dominated by high molecular weight compounds and this was attributed to the nearby sources (steel plants with electric arc furnaces) emitting significant amounts of particle-phase PAHs.…”

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.

A framework was developed to estimate dry deposition of polycyclic aromatic compounds (PACs), including 17 polycyclic aromatic hydrocarbons (PAHs), 21 alkylated PAHs, and 5 parent and alkylated dibenzothiophenes (DBTs), to various land covers surrounding three monitoring sites in the Athabasca oil sands region. Modeled dry deposition velocities for various gaseous PACs and over various land covers were mostly in the range of 0.01-0. the total dry and 60% of the total wet deposition budget, suggesting the importance of including this group of PAHs in the atmospheric deposition budget estimation for subsequent ecosystem impact studies.

The top-soil samples were collected from urban, industrial, agricultural, and rural sites to investigate the modification in the elemental composition due to anthropogenic influence in one of the biggest city of Turkey, namely Izmir. The elemental profiles were dominated by lithophilic elements such as Al, Ca, Fe, Mg, K, and sea salt element, Na, which is typical for Mediterranean region. The trace elemental concentrations showed significant variation with higher concentrations in the industrial sites, particularly in the vicinity of iron-steel producers from scrap materials (EAF-Steels). Lead, Zn, and Cd around EAF-Steels were found to be higher than other sites. Comparison to universal upper crusts and local reference soil has shown that Izmir top-soils were contaminated in terms of many trace elements, most probably due to anthropogenic activities. Correlation matrix, crustal enrichment factors, and factor analysis were applied to investigate the extent of soil modification and possible sources. The results indicated that the elemental profiles of top-soils were mainly determined by parent materials; however, anthropogenic activities were found to be factor effective on the profile.
