项目摘要

Some atmospheric aerosols collected in Toyama, Kanazawa and Vladivostok were analyzed to estimate the relationship between the growth of economic activities in the boundary area of China, Russia and North Korea. The United Nations planned the economic development in this area called "The Greater Tumen Initiative". But because of the bad economic situation of North Korea, the development really carried out in the area of Vladivostok suburbs and northeastern China. So, we had focused on the study of the relationship between the economic growth of Vladivostok suburb area and northeastern China area, and the chemical components of atmospheric aerosols in Toyama, Kanazawa, Vladivotok and Liaoning Province.Concentration of polycyclic aromatic hydrocarbons (PAHs) and nitro polycyclic aromatic hydrocarbons (N-PAHs) in the airborne particulate collected in some places in northeastern China showed more than 10 times higher than those of Tokyo, suggesting that main energy source in northeastern China are coal burning. This may resulted in the high concentration of PAHs and N-PAHs in the aerosols. Changes in the energy source or the development of combustion system in these area will contribute to the decrease in the concentrations. In 3 years of the research period, we could not confirm the decrease of the concentrations.Because of the changes in the Russian policy during the research period, we could not continue bringing out some samples collected in Russia to Japan. So finally, we analyzed a sample which was collected in Vladivostok before the political change in Russia, and we have compared the data on the analysis of the aerosol samples collected in Toyama which were analyzed by ICP spectrometry in Japan and XRDF in Russia. The results will be published in the report.

分析了在富山、金泽和海参崴采集的部分大气气溶胶，以估计中俄朝边境地区经济活动增长之间的关系。联合国规划了这一地区的经济发展，称为“大图们江倡议”。但由于朝鲜经济状况不佳，开发活动主要集中在海参崴郊区和东北地区。因此，我们重点研究了海参崴郊区和东北地区的经济增长与富山、金泽、海参崴和辽宁省。多环芳烃和硝基多环芳烃的浓度在中国东北一些地方收集的空气中颗粒物显示比东京高出10倍以上，这表明中国东北的主要能源是燃煤。这可能是导致大气中多环芳烃和N-PAHs浓度较高的原因。这些地区能源的变化或燃烧系统的发展将有助于浓度的降低。在3年的研究期间，我们无法确认浓度的降低。由于研究期间俄罗斯政策的变化，我们无法继续将在俄罗斯收集的一些样品带到日本。最后，我们分析了在俄罗斯政治变革之前在海参崴采集的样品，并将在日本富山采集的气溶胶样品的分析数据与在俄罗斯用ICP光谱法和XRDF分析的数据进行了比较。结果将在报告中公布。
