摘要：

The mass concentration and size distribution of aerosols in Tokaimura were investigated using a high-volume and a low-volume Andersen sampler. A difference was found using the two samplers: the concentration of total aerosols determined with the high-volume sampler is smaller than that of the low-volume sampler by 70-90% throughout the year. Compared to the high-volume sampler, low-volume sampler gave lower concentration for aerosols > 7 mu m, higher concentration for aerosols of 3.3-7.0 mu m and < 1.1 mu m, though similar results for aerosols of 1.1-3.3 mu m. The low-volume sampler was found to have better separation efficiency and higher accuracy. (c) 2008 Chinese Society of Particuology and Institute of Process Engineering, Chinese Academy of Sciences.
