| Abstract: | Using a 10-stage cascade impactor, atmospheric aerosols were collected from urban and non-urban areas in Nanjing, China. The shapes of average mass distribution were multimodal for both the urban and non-urban samples. The average mass concentration of atmospheric aerosols in the industrial/agricultural area was larger than in city center and natural park areas. The mass median diameter (MMD) were 0.80 μm, 0.51 μm and 0.46 μm for the natural park, city center and industrial/agricultural samples, respectively. In both the urban and non-urban areas, the particles in accumulation and coarse modes were the main contributors to total mass concentration, the particles in Aitken nuclei mode were only a few percent of total mass. |
