“…The research conducted in Xuanwei, Qujing city also indicated that the PAHs with 4-5 aromatic rings were the dominant PAHs in indoor air (Lv et al, 2010). However, lowmolecular-weight PAHs with 2-3 aromatic rings made up an average of 75.3% of the total parent PAHs in coke oven-containing workplaces in China (Li et al, 2010, Mu et al, 2014, which might explain why pyrene contributed a lower PAH burden in the urine of the workers versus the farmers. Furthermore, a study performed in Peru by the Table 4 Concentrations of the daily intake of PAHs and benzene estimated from the urinary metabolites measured in the workers and the farmers (units: mg/day, assuming that an adult has a body weight (BW) of 60 kg).…”

“…The OC/EC ratio at site D was 2.35, indicating that secondary pollution exists at site D. Bieniek and Lusiak (2012) reported that coking emits large amounts of SOC precursors such as toluene, m-xylene, and p-xylene. Moreover, coking emits a large amount of semi-VOCs such as PAHs, and gas-to-particle conversion of these compounds influence OC concentrations in the coking plant air (Shi et al, 2011;Mu et al, 2013;Mu et al, 2014). Therefore, the OC distribution in the coking plant air was due to the cumulative effect of coking emissions, atmospheric dispersion and dilution, SOC formation from VOCs, and gas-to-particle conversion of semi-VOCs.…”

“…OC and EC at sampling sites E and F are affected not only by fugitive emissions but also by stack emissions from coal charging, coke pushing, and coke-oven gas combustion . Gas-and solid-phase redistribution of semi-VOCs may be another factor that causes poor OC-EC correlation at sites E and F (Liberti et al, 2006;Mu et al, 2014).…”

To investigate the characteristics of organic carbon (OC) and elemental carbon (EC) in the ambient air of coking plant, particulate matter samples were collected and analyzed. The OC and EC mass concentrations were in the range of 104.2-223.2 µg/m 3 and 93.7-237.8 µg/m 3 , respectively, which were much higher than those in the ambient air of industry, highway, and urban roadway tunnel. The OC concentrations did not significantly differ at the coke side and the machine side, whereas the EC concentration was significantly higher at the coke side. The OC/EC ratios ranged from 0.74 to 2.35, and coking was the primary source of OC and EC. Carbonaceous aerosol was a large component in the ambient air, and the total carbonaceous aerosol (TCA) accounted for 39.1%-73.0% of the total suspended particulates (TSP). TCA contributions to TSP were consistent at the coke side and the machine side, and both contributions were lower than those at other sampling sites. OC and EC emission control must be strengthened for improving coking plant air quality and reducing health hazards to coke-plant workers. OC-EC correlation was evident, with a correlation coefficient of 0.976 (p < 0.05) at the coke-oven top, coke side, and machine side, whereas no significant correlations were observed at sites downwind of the coke oven (p > 0.05).

“…Early findings apparently focused on the air quality level worsened by agricultural waste burnings, wildland fires, and accidental biomass combustions associated with trans boundary haze pollution from neighbouring countries of Thailand (Pengchai et al, 2009;Oanh et al, 2011;Huang et al, 2013;Shi et al, 2014). Apart from biomass burnings, vehicular exhausts, domestic heating, industrial emissions and other fugitive sources can be acknowledged as important sources of PAHs (Riva et al, 2011;Wei et al, 2012;Amodio et al, 2013;Slezakova et al, 2013;Mu et al, 2014). As a consequence, there is a growing concern for human exposure risk to airborne carcinogens.…”

In Northern Thailand, wildland fire during cold period releases large amounts of smoke and fine particles into the atmosphere. The fine particles include several persistent organic compounds such as PAHs. In this study, PM 2.5 -bound PAH concentrations in the air of nine administrative provinces, namely Chiang-Mai, Chiang-Rai, Nan, Phayao, Mae Hong Son, Phrae, Lampang, Lamphun, Uttaradit (N Thailand) were determined during the wildland fire and non-wildland fire seasons. The monitoring strategy comprised two campaigns in each season. PM 2.5 was collected using MiniVolTM portable air samplers (Airmetrics) with quartz fibre filters. Both PAHs and their B[a]P Equivalent concentrations of other urban cities around the world were significantly higher than those of northern provinces for both seasons. The average cancer risks observed at nine administrative provinces were 8.525 × 10 -4 ± 3.493 × 10 -3 and 2.558 × 10 -3 ± 6.986 × 10 -3 for ingestion rate of 50 and 100 mg day -1 , respectively. The excess cancer risks of world cities for ingestion rate of 50 and 100 mg day -1 were much higher than those of Northern Thailand for 851 and 567 times in that order. Dust ingestion was exceedingly critical to non-dietary PAH exposure in comparison with PM 2.5 inhalation. These results are in good agreement with those of previous studies, underlining the significance of indoor air quality on long-term adverse respiratory diseases in Asian cities.
