Hazardous polycyclic aromatic hydrocarbons (PAHs) and nitropolycyclic aromatic hydrocarbons (NPAHs) are mainly originated from imperfect combustion of fossil fuels such as petroleum and coal. The consumptions of not only petroleum but also coal have been increasing in the East Asian countries. We collected airborne particulates in ten cities in Japan, Korea, China and Russia and six PAHs and eleven NPAHs were determined by HPLC methods using fluorescence and chemiluminescence detections.
The total PAH concentrations were much higher in Chinese cities (Fushun, Tieling, Shenyang and Beijing) than those in other cities (Vladivostok, Busan, Kanazawa, Kitakyushu, Sapporo and Tokyo). The total NPAH concentrations were also higher in Chinese cities than those in the other cities.
The [NPAH]/[corresponding PAH] ratios are much larger in diesel-engine exhaust particulates than those in coal-burning particulates. The [1-nitropyrene]/[pyrene] ratio of airborne particulates was much smaller in the four Chinese cities, suggesting that coal combustion systems such as coal heaters were the main contributors. On the other hand, the ratios were larger in Korean and Japanese cities, suggesting the large contribution of diesel-engine vehicles.
