| Outline of Final Research Achievements |
Semi volatile organic compounds (SVOCs) could cause asthma or allergies in indoor environment. SVOCs exist as adsorption onto airborne particles as well as gas phase. However, influence on this mechanism by particles residence time and surface characteristics such as pore size distribution and specific surface area hasn’t considered in previous studies. The aims of this study are to examine SVOC adsorption onto airborne particles depending on particles surface characteristics and residence time. SVOC adsorption experiments were carried out for airborne test particles of carbon black and silica which have 4 types of different particle diameter respectively in different residence time t = 7.5 ~120 min with DEHP as SVOC. Adsorbed DEHP amount per particles surface area is almost the same in each test particle and each residence time.
