Number of aerosol, CO, CO₂ and TVOC after one-, two-, three-cigarettes smoking were monitored with time every 10 minute for 180 minutes in the seminar room (volume 51.1 ㎥) when poorly-ventilated. IAQ monitor (IAQRAE, model PGM-5210) and PortCount (TSI, model 8020) were used for monitoring. Aerosol was decreased with exponential decay equation and it was estimated that number of aerosol would be long suspended (one cigarette 75/㏄. two cigarettes 66/㏄, three cigarettes 141/㏄ by 8hrs after smoking). While CO was also decreased with exponential or linear decay equation and correlated with number of aerosol strongly, TVOC and CO₂ were increased with linear equation in accordance with time lag. Most of TVOC and CO₂ were above standard levels of Korean Indoor Air Quality (Ministry of Environment) without regarding number of cigarettes. When naturally ventilated, all of CO, CO₂ and TVOC concentrations were dramatically decreased below standard levels of Korean Indoor Air Quality.
