환기가 불량한 실내공간에서 담배연기에 의한 CO, CO2, TVOC 및 에어로졸의 변화

Changes of CO, CO2, TVOC and Aerosol of Tobacco Smoke in a Poorly-Ventilated Indoor

Number of aerosol, CO, CO2 and TVOC after one-, two-, three-cigarettes smoking were monitored with time every10 minute for 180 minutes in the seminar room (volume 51.1 m3) when poorly-ventilated. IAQ monitor (IAQRAE,model PGM-5210) and PortCount (TSI, model 8020) were used for monitoring. Aerosol was decreased with exponentialdecay equation and it was estimated that number of aerosol would be long suspended (one cigarette 75/cc. twocigarettes 66/cc, three cigarettes 141/cc by 8hrs after smoking). While CO was also decreased with exponential or lineardecay equation and correlated with number of aerosol strongly, TVOC and CO2 were increased with linear equation inaccordance with time lag. Most of TVOC and CO2 were above standard levels of Korean Indoor Air Quality (Ministryof Environment) without regarding number of cigarettes. When naturally ventilated, all of CO, CO2 and TVOC concentrationswere dramatically decreased below standard levels of Korean Indoor Air Quality.
