East Asian countries surrounding Japan Sea, such as Japan, China, Korea and Russia, have shown significant change of atmospheric conditions with fast industrial development. Atmospheric behaviors of carcinogenic polycyclic aromatic hydrocarbon (PAH) and nitropolycyclic aromatic hydrocarbon (NPAH) were studied in this area. Their atmospheric concentrations decreased in Japanese cities by the effective countermeasures against automobile exhaust. However, several cities in China and Russia showed the increasing tendency of the concentrations. By using the analytical results, the emission inventory and the chemical transport model were newly developed. In the atmosphere, on the other hand, several oxidized derivatives of PAHs and NPAHs formed through secondary formation were identified. Several compound of metabolites and secondary formed derivatives of PAHs and NPAHs showed strong biological activities such as mutagenicity and endocrine disruption.

日本海周围的东亚国家，例如日本，中国，韩国和俄罗斯，随着快速工业发展的大气状况发生了重大变化。在该地区研究了致癌多环芳烃（PAH）和硝基二环芳烃（NPAH）的大气行为。通过反对汽车排气的有效对策，日本城市的大气浓度降低了。但是，中国和俄罗斯的几个城市表明，集中度的趋势不断增加。通过使用分析结果，新开发了发射库存和化学传输模型。另一方面，在大气中，通过次级形成形成的PAH和NPAH的几种氧化衍生物。代谢产物和二次形成的PAH和NPAH衍生物的几种化合物表现出强大的生物学活性，例如诱变性和内分泌破坏。
