Owing to rapid development and economic growth in Asian region, transboundary environmental problems become more severe than before, particularly for long-range transport of air pollutants. Therefore, the goals of this study are to study the Asian dust, biomass burning and acid substances via long-range transport and their impact on the air quality in Taiwan, as well as the source and receptor relationship. We integrated the surface measurements including aerosol and precipitation chemistry, and remote sensing techniques of lidar and satellite to study the emission, transport and deposition of Asian dust and biomass burning aerosols. We found that the washout and rainout effects of Asian dust can significantly eliminate the dust concentration, while it may affect the ecosystem due to wet deposition. In summary, the transport of air pollutants from China to Taiwan has become an important issue that a significant amount of observed air quality is contributed by China via long-range transport of air pollutants.
