| Research Abstract |
Secondary organic aerosol(SOA) formation from volatile organic compounds(VOCs) is an important factor of the indoor pollutions. There are many reports about particle for mation by the reaction of d-Limonene and O_3 under UV irradiation. While there are few study about SOA from p-Dichlorobenzene, which is used for a mothball in Japan.
In this study, the screening experiments were performed on particle formation from VOCs, especially d-Limonene and p-Dichlorobenzene, without initial O_3 source. And experiment at the real room was performed on exposure to VOCs emitted from housekeeping products under ordinary usage in the residential room air. Particle, NOx and O_3 concentrations in the air were monitored. At the case of experiment with d-Limonene under UV irradiation, particle formation was started when O_3 was generated in the gasbag. In contrast, for experiments with p-Dichlorobenzene(without NOx), particles(<50nm) generated immediately after starting UV irradiation.
