| Outline of Final Research Achievements |
In this study, the effect by the existence form of water in the air is examined for the generation and behavior of indoor secondary organic aerosol (ISOA) by the experiments and prediction models for the indoor contamination mechanism. The following results are obtained.
By the experiment for the generation of ISOA, the generation and time growth characteristics are obtained by the differences of initial conditions such as moisture concentration. The possibility to generate the activated mist and the reaction and the decomposition of the hydrophobic VOC gas by the activated mist are shown by the experiment of the accelerated oxidation method with ultrasonic atomization technique. For the prediction model, the responsibility of cluster formation with water molecules is shown by molecular orbital and dynamics calculations. The exposure effect is reviewed for the health assessment. Indoor ultraviolet intensity is investigated for the ultraviolet environment.
