“…The source of PAHs was petroleum for Flt/(Flt + Pyr) < 0.4, petroleum combustion for 0.4 < Flt/(Flt + Pyr) < 0.5, and biomass coal combustion for Flt/(Flt + Pyr) > 0.5. It was also petroleum for Ind/(Ind+ BghiP) < 0.2, petroleum combustion for 0.2 < Ind/(Ind + BghiP) < 0.5, and biomass coal combustion for Ind/(lnd + BghiP) ≥ 0.5 [18,27,28]. rate of Banwol National Industrial Complex is presented in Figure 6.…”

“…The concentration of particulate Σ18 PAHs was the highest in winter (7.92 ± 4.04 ng/Sm 3 ), followed by autumn (2.58 ± 2.14 ng/Sm 3 ), spring (1.83 ± 1.99 ng/Sm 3 ), and summer (1.43 ± 0.95 ng/Sm 3 ). This result may be due to the increased consumption of fossil fuels in winter, which led to a higher concentration of particulate PAHs in the atmosphere [16][17][18]. In summer, instead, with the highest temperature and the lowest fossil fuel consumption, there was the lowest concentration of particulate PAHs.…”

“…The source of PAHs was petroleum for Flt/(Flt + Pyr) < 0.4, petroleum combustion for 0.4 < Flt/(Flt + Pyr) < 0.5, and biomass coal combustion for Flt/(Flt + Pyr) > 0.5. It was also petroleum for Ind/(Ind+ BghiP) < 0.2, petroleum combustion for 0.2 < Ind/(Ind + BghiP) < 0.5, and biomass coal combustion for Ind/(lnd + BghiP) ≥ 0.5 [18,27,28]. Figure 6 shows that the Flt/(Flt + Pyr) ratio was higher than 0.5 in winter, spring, and autumn, according to the PAH results of this study, indicating the dominant influence of biomass coal combustion.…”

“…Figure 7 shows the slope of Flt and Pyr by season to identify source characteristics. Automobile emissions affected PAHs at a Flt and Pyr slope of 1.42, biomass combustion at 0.96, coal (bituminous coal + lignite) combustion in the industrial area at 0.90, lignite combustion in the industrial area at 0.77, and bituminous coal combustion in the industrial area at 0.64 [18,[31][32][33]. Figure 7a shows that in winter, the slope was 0.58 and 0.57 for the PAHs results of this study and those of the Siheung Jungwang monitoring station, respectively, confirming the impact of coal combustion (bituminous coal).…”

Particulate and gaseous polycyclic aromatic hydrocarbon (PAHs) samples (n = 108) were measured every six days from January to December 2022 at a representative point in the Korean Banwol National Industrial Complex. The measurement results revealed that the concentration of particulate Σ18 PAHs was 7.92 ± 4.04 ng/Sm3 in winter, 1.83 ± 1.99 ng/Sm3 in spring, 1.43 ± 0.95 ng/Sm3 in summer, and 2.58 ± 2.14 ng/Sm3 in autumn. The concentration of gaseous Σ18 PAHs was 3.32 ± 3.72 ng/Sm3 in winter, 6.34 ± 5.95 ng/Sm3 in spring, 8.33 ± 8.13 ng/Sm3 in summer, and 3.88 ± 1.71 ng/Sm3 in autumn. The results of the correlation analysis showed that particulate PAHs have positive relationships with PM10 and PM2.5 and negative relationships with temperature and O3. The diagnostic ratio and PAHs component slope showed that the emission source characteristics of the Banwol National Industrial Complex were dominated by biomass coal combustion over four seasons; however, the influence of petroleum combustion (automobile emissions) was not negligible. As for coal combustion, bituminous coal was the most influential, and lignite was relevant in summer and autumn.

“…Meanwhile, Hussain et al [18] found that the concentration of PAHs shows different distribution depending on the season. Lim et al [38] also revealed that the concentration distribution of particulate PAHs in the atmosphere displayed seasonal characteristics in South Korea. They reported that the risk of PAHs in the atmosphere tends to be determined by PAHs in particulate form rather than PAHs in gaseous type, and the concentration was higher in winter than in summer.…”

In this study, the occurrence and distribution of polycyclic aromatic hydrocarbons (PAHs) in road dust sediment(RDS) deposited from main traffic roads as well as residential and industrial areas were examined with a total of 144 samples in seasons. Based on the results, the concentrations of PAHs were found to be higher in winter and ranged between 0.15 and 1.94 mg/kg with an average of 0.65 mg/kg. The results indicate that pyrene, fluoranthene, phenanthrene, and benzo(ghi)perylene were commonly found in RDS, likely originated from vehicle exhaust emissions and fuel combustion by the diagnostic ratio study. Non-cancer risk from PAHs for humans exposed to RSD was found to be low (HI 1.2E-05). The estimated excess cancer risks by PAHs in RDS was also much less than the regulatory guideline for cancer risk (1×10-6). Thus, current concentrations of PAHs in RDS are expected to be pose no threat to humans under the assumed exposure scenarios with applied exposure factors. However, more extensive and long-term sample analysis for gaseous and particulate PAHs is still warranted to determine potential risks to humans and the fate in the environment, since their concentration and distribution can be influenced by micro-metrological conditions, traffic volumes, or road clean-up conditions.
