Abstract

This study measured five apartments in the Daejeon. There is higher fluctuation for ambient air particle conditions. The average PN (particle number) concentrations was 5.2x10⁸/m³. There are differences between five sites because of fluctuation for ambient air conditions. Particle concentration has different each occupant schedule. I/O ratios were different by occupancy schedules. Indoor particles exceeded 0.7 μm was significant emitted indoor activities. This result comes from two reasons. 1) Penetration by envelopes. 2) Indoor sources by occupants' activities. PN decay rate (a+k) were 0.49-4.29 h^-1 during indoor peak events. Total emitted particles (σ) was 0.0136.15 x 10¹³ particles per events. The cooking generated PN were wide range because of different event conditions. The ventilation rate is not enough to remove particles.
