“…This result was in line with those reported for PAHs, PCBs and BDE-209, such as 0.45 AE 0.35 cm s À1 for PAHs and 0.74 AE 0.23 cm s À1 for PCBs (Esen et al, 2008), and 0.28 AE 0.01 cm s À1 for BDE-209 (Li et al, 2010b). However, the bulk deposition velocities were approximately ten times lower than the dry PAH deposition velocities reported by Bozlaker et al (2008) and Vardar et al (2004). The discrepancy among these deposition velocities could be attributed to the differences in the sampling collection procedures, sampling sites and particle size distribution.…”

“…This was evident by the more shallow slopes obtained from the plots of logK P versus logK OA at the suburban site compared to those for urban sites. Recently, Vardar et al [45] have reported steeper slopes for lake samples relative to the land samples in Chicago. It was suggested that the observed differences between the lake and land samples may be due to the different properties of particles (i.e., aged particles as a result of longer residence time for lake samples), non-exchangeability and differences in activity coefficients of PAHs.…”

“…The soot model predictions were relatively better and measured to modeled ratios ranged between 0.11 (BghiP) up to 232 (FLN) (30 AE 141, average AE SD) and 0.6 (CHR) up to 5.6 (FLN) (2.3 AE 2.7, average AE SD) for suburban and urban sites, respectively. Recent studies reported that the soot-based model showed a good predictability at an urban site (Chicago, IL) but underestimated the values at a rural site (Eagle Harbor) by an order of magnitude [45,46]. It was suggested that characterizing atmospheric soot, determining the temperature dependence of soot-air partitioning, and quantifying the exchangeable fraction of each PAH on aerosols will help to explain the differences between predicted and observed partition coefficients [46].…”

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.

“…Plenty of studies have been carried out in the surface water and sediments of seas, oceans [1,5,[11][12][13][14][15][16], and atmosphere [17][18][19][20], while the food investigations [17,21] have also been conducted extensively worldwide. However, studies on the small catchment which were affected greatly by the human activities were deficient.…”

Polycyclic aromatic hydrocarbons (PAHs) in the dated sediments from the Shuanglong catchment in the southwest of China were measured to characterize source inputs. The PAHs concentrations in the priority controlling list of US EPA (∑PAHs) ranged within 102.47∼563.24 ng g −1 , with an average value of 207.18 ng g −1 . The 2-3 rings PAHs were predominant, accounting for 73.77% of ∑PAH. According to the classification of pollution levels, ∑PAHs concentrations in the sediments are within the range of moderate pollution level. Both the total and individual PAH concentrations changed with the depth. The profile distribution of PAHs concentration in the sediments suggested that PAHs acted as an effective way to reconstruct the historical trends of socioeconomic changes in the study areas. Results of Ant/(Ant + Phe), Fla/(Fla + Pyr), and BaA/(BaA + Chry) show that petroleum and petrogenic matter are attributed to the potential pollution source in the Shuanglong catchment. The coal combustion and incomplete combustion of gasoline and fossil fuel are dominant. TOC contents had positive correlation with ∑PAHs ( 2 = 0.72, < 0.001), 2-3 rings ( 2 = 0.44, < 0.001), 4-ring ( 2 = 0.78, < 0.001), and 5-6 rings ( 2 = 0.62, < 0.001).
