Abstract
In relation to atmospheric environment, I have studied two different research fields "Field sampling of atmospheric aerosols" and "Air purification techniques for organic gases." In this paper, the outline of these researches are introduced based on field sampling of atmospheric ultrafine particles near the emission sources using a new developed inertial filter (INF) sampler, and investigation of effective treatment for VOC gases and their decomposition products using combined advanced oxidation process (AOP) techniques.
