Indoor Air Pollution Concentration by Elapsed Time of Staying in NoRaebang : Singing room Furnished with a Karaoke

The purpose of this study was to grasp the actual state of indoor air quality by stay time elapsed in NoRaebang, singing room furnished with a karaoke. Method was field survey with measurement on air pollutant factors and observation on influencing factors of them. Field surveys were carried out in 3 NoRaebang from 16th to 18th of December 2006. Measuring elements were indoor temperature, CO2, CO, PM10 and TVOC. As results, the averages of indoor temperature in each NoRaebang were 20.2～24.3℃. The averages of CO2 concentration were 1,578.1～2,578.6 ppm, all measured points exceeded the standard(1,000 ppm). The means of CO and PM10 concentration were 3.2～4.0 ppm and 40～56.4 ㎍/㎥, which were kept within the standard(10 ppm and 150 ㎍/㎥). The means of TVOC concentration were 0.3～0.6 ppm which exceeded the standard(0.12 ppm). The influencing factors of indoor air pollutant concentration were renovation of facility, number of users, and kind of user activity, etc.
