Atmospheric aerosols, collected from China, Korea, Mongolia, India and Japan as well as coastal and remote islands, have been studied for organic chemical compositions. The aerosols from Manshan, 40 km north of Beijing, showed higher concentrations of dicarboxylic acids such as oxalic acid than those from Beijing, suggesting a secondary (photochemical) production of water-soluble organic acids during atmospheric transport. Indian aerosols from New Delhi showed very high concentrations of low molecular weight diacids. Aerosols from Ulaanbaatar were studied for the hygroscopicity, indicating that the growth factor (Gf=1.22) is close to that of biomass burning aerosols.
