Analysis of polycyclic aromatic hydrocarbons (PAHs) and nitropolycyclic aromatic hydrocarbons (nitroarenes) in the atmosphere in the area of Pan-Japan-Sea and removal of these organic compounds with iron oxides have been investigated. Concentration of these compounds in the atmosphere of Toyama, Kanazawa, Vladivostok and Shenyang show ed differences in the amount and the composition. The concentration of these organic compounds in Shenyang and her suburb was more than 10 times higher than that in Kanazawa. The ratio of 1-nitropyrene, one of the nitroarenes, to pyrene, one of the PAHs, suggested that main source of these compounds in Shenyang was coal combustion, though in Kanazawa and Toyama the main source is diesels-engine exhaust. Iron oxide (haematite) reacted with these compounds in helium stream at 300 〜 700 ℃ and removed them in the form of blackish particles on the iron oxide, indicating that the iron oxide catalyzed the thermal decomposition of these organic compounds. X-ray study showed that magnetite phase was observed after the reaction of haematite with the organics. This indicates that haematite was partially reduced to magnetite with the organics. By flowing air instead of helium, the organic, compounds were removed completely without forming blackish compounds on iron oxide, suggesting that oxygen in air oxidised the blackish compounds, probably the elementary carbon, and removed from the surface in the form of carbon dioxide. No phase transformation was observed from X-ray analysis of the haematite sample, indicating that haematite was not reduced to magnetite in air stream. Efficiency of removal of nitroarenes were higher than that of PAHs. Induction by nitro group may contributed to enhance the removal efficiency of PAHs.

研究了日本海海域大气中多环芳烃（PAHs）和硝基多环芳烃（Nitropyclic aromatic hydrocarbons，Nitroarenes）的分析以及铁氧化物对这些有机物的去除作用。这些化合物在富山、金泽、海参崴和沈阳大气中的浓度在数量和组成上存在艾德差异。沈阳市及其郊区大气中这些有机物的浓度比金泽市高10倍以上。1-硝基芘（硝基芳烃）与芘（多环芳烃）的比值表明，沈阳地区主要来源于燃煤，而金泽和富山地区主要来源于柴油机尾气。在300 ~ 700 ℃的氦气流中，氧化铁（赤铁矿）与这些化合物发生反应，并在氧化铁上以黑色颗粒的形式将它们除去，表明氧化铁催化了这些有机化合物的热分解。X射线衍射研究表明，磁铁矿相后，观察到的赤铁矿与有机物的反应。这表明，赤铁矿与有机物部分还原为磁铁矿。通过流动空气而不是氦气，有机化合物被完全去除，而不会在氧化铁上形成黑色化合物，这表明空气中的氧气氧化了黑色化合物，可能是元素碳，并以二氧化碳的形式从表面去除。没有相变观察到从X射线分析的赤铁矿样品，表明赤铁矿没有减少到磁铁矿在空气流。硝基芳烃的去除率高于多环芳烃。硝基的诱导作用可能有助于提高多环芳烃的去除率。
