项目摘要

Airborne particulates were collected in seven cities in the Pan-Japan Sea countries, Shenyang (China), Vladivostok (Russia), Seoul (South Korea), Kitakyushu, Kanazawa, Tokyo and Sapporo (Japan), in winter and summer. In addition, particulates from domestic coal-burning stoves and particulates from diesel-engine automobiles were collected. Nine polycyclic aromatic hydrocarbons (PAHs), fluoranthene, pyrene (Pyx), benz[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, benzo[ghi]perylene and indeno[1,2,3-cd]pyrene, and four nitropolycyclic aromatic hydrocarbons (NPAHs), 1,3-, 1,6-, 1,8-dinitropyrenes, and 1-nitropyrenes (1-Np) in the extracts from the particulates were analyzed by HPLC with fluorescence and chemiluminescence defections, respectively. The mean atmospheric concentrations of PAHs in Shenyang and Vladivostok were substantially higher than those in Seoul, Tokyo, Sapporo, Kitakyushu and Kanazawa. However, the mean atmospheric concentrations of NPAHs were at the same levels in every city except for Kitakyushu. Obvious seasonal variations (winter > summer) in the PAR and NPAH concentrations were observed in each city. In order to study the major contributors of atmospheric PAHs and NPAHs in these cities, cluster analysis and factor analysis were used and three large clusters were identified. Furthermore, the concentration ratios of 1-Np to Pyr were significantly smaller in Shenyang, Vladivostok and Kitakyushu and the values were close to those of particulates in the exhaust from coal stoves. However, the ratios were larger in Seoul, Kanazawa, Tokyo and Sapporo and the values were close to those of particulates in the exhaust from diesel-engine automobiles. Our results show that the concentration ratio of 1-Np to Pyr is an useful indicator of the contributions made by diesel-engine vehicles and coal combustion systems to particulates in urban air.

冬季和夏季，在泛日本海国家的七个城市，沉阳（中国）、符拉迪沃斯托克（俄罗斯）、首尔（韩国）、北九州、金泽、东京和札幌（日本）收集了空气中的颗粒物。此外，还收集了家用燃煤炉的颗粒物和柴油发动机汽车的颗粒物。九种多环芳烃 (PAH)、荧蒽、芘 (Pyx)、苯并[a]蒽、屈、苯并[b]荧蒽、苯并[k]荧蒽、苯并[a]芘、苯并[ghi]苝和茚[1 ,2,3-cd]芘和四种硝基多环芳烃 (NPAH), 1,3-,通过 HPLC 分别通过荧光和化学发光缺陷分析颗粒提取物中的 1,6-、1,8-二硝基芘和 1-硝基芘 (1-Np)。沉阳和符拉迪沃斯托克的大气中多环芳烃平均浓度显着高于首尔、东京、札幌、北九州和金泽。然而，除北九州外，各城市的 NPAH 平均大气浓度处于相同水平。各城市PAR和NPAH浓度存在明显的季节变化（冬季>夏季）。为了研究这些城市大气PAHs和NPAHs的主要贡献者，采用聚类分析和因子分析，确定了三大类。此外，沉阳、符拉迪沃斯托克和北九州的1-Np与Pyr的浓度比明显较小，且与煤炉废气中颗粒物的浓度接近。然而，首尔、金泽、东京和札幌的比率较大，并且该值接近柴油发动机汽车排气中的颗粒物的值。我们的结果表明，1-Np 与 Pyr 的浓度比是衡量柴油发动机车辆和燃煤系统对城市空气中颗粒物贡献的有用指标。
