“…This indicated that atmospheric nitro-PAH formation was influenced by not only the concentration of the parent PAHs and NO 2 but also other factors such as concentration of OH radicals, NO 3 radicals, and other oxidants. Our results are consistent with a previous report that investigated diurnal changes of nitro-PAHs (Kameda et al, 2004a).…”

“…In comparison, 2-NP is formed only via OH radical-initiated reaction of PY (Zielinska et al, 1986). The relative importance of these two pathways for nitro-PAH formation can be determined from the 2-NF/2-NP ratio; several reports have utilized this index to discuss the occurrence of radical initiated-formation (Kameda et al, 2004a;Bamford and Baker, 2003;Feilberg et al, 2001). The increase in the 2-NF/2-NP ratio between 1997-1998 and 2006-2007 indicates that the NO 3 radical-initiated nitration of PAHs has become more important.…”

The effectiveness of the government regulation on tail-pipe emission for diesel vehicles issued in 2003 in Tokyo was evaluated in this study. Variations in annual average concentrations of polycyclic aromatic hydrocarbons (PAHs) and nitro-PAHs associated with airborne particulate matter were investigated in connection with the variation in airborne elemental carbon (EC) concentration in downtown Tokyo,

“…After dispersion into the atmospheric environments, they may also deposit on ground surfaces, and discharge into and pollute water environments. Though many researchers have investigated the behaviors of nitro-PAHs in atmospheric environments (Arey et al 1987;Ciccioli et al 1996;Dimashki et al 2000;Marino et al 2000;Feilberg et al 2001;Bamford and Baker 2003;Kameda et al 2004Kameda et al , 2006Tang et al 2005;Crimmins and Baker 2006;Sienra and Rosazza 2006;Albinet et al 2007;Vasconcellos et al 2008;Kawanaka et al 2008), there has been less investigation of nitro-PAHs in water environments.…”

Atmospheric and sea sediment concentrations were measured for eight nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) and three unsubstituted PAHs in a suburban area and sea sediments in the Hiroshima Bay watershed area, Japan, from July to December, 2006 (atmospheric particulate matter) and in September and November, 2004 (sea sediments). Atmospheric concentration was higher in winter than summer for both nitro-PAHs and PAHs. Concentrations in sea sediments were less than 10%, and pattern was similar to those of atmospheric particles. Several combustion emission sources were also measured, and the 1-NP/Pyr ratio was compared to environmental values. The ratio of atmospheric and sea sediments were significantly lower than diesel particulate matters. Further, the vehicle emission loading and sea sedimentation loading was evaluated in this watershed area, and from the comparison, the existence of other important sources PAHs were suggested.

“…The criteria for such fine dusts are classified according to their size, and the composition may vary depending on the source and environmental factors [ 32 ]. Although the compositions of PM have not yet been clarified, past studies have shown that there is a difference in mutagenicity (capacity to cause mutations) depending on the day of the week [ 33 ], time of day [ 34 ], presence of urban/industrial facilities [ 35 ], altitude [ 36 ], and air pollutant concentration [ 37 , 38 , 39 , 40 , 41 , 42 ]. Especially in areas with urban and industrial facilities and areas with high concentrations of air pollutants, the mutagenicity of PM was higher.…”

In Korea, lung cancer is a common cancer, and has the highest mortality rate in both males and females. Approximately 80% of lung cancer is due to smoking, and the remaining cases are known to be due to genetic factors, history of respiratory disease, infection, diet, and occupational and environmental factors. Since the occupational and environmental hazards may differ from region to region, the lung cancer risk may differ too. To identify this, we selected seven metropolitan cities, and compared occupational and environmental hazards. Furthermore, we calculated smoking rate adjusted standardized rate ratio (ratio of 10-year cumulative age-standardized incidence rate of lung cancer during the 2000–2009 period at target region versus reference region) to compare the regional lung cancer risk. The result showed that the emissions and concentrations of air pollutant were higher in high-risk regions, and the risk of lung cancer was significantly elevated in such area. In this study, we simultaneously consider the cumulative incidence, age-standardization and smoking rate adjustment. Therefore, we can conclude that the validity of the finding of this study is higher than that of past studies. In conclusion, the occupational and environmental hazards have an effect on lung cancer.
