Zusammenfassung:This study is to investigate the characteristics of emission concentration according to wallpaper sort and emission time using small chamber method. The target compounds included 45 VOCs and formaldehyde, which were respectively determined by adsorption sampling and thermal desorption coupled with GC/MS method, and by sampling in DNPH cartridge and HPLC method. The emission factor of TVOC and HCHO was detected to $1.1mg/m^2{\cdot}h$ and $0.01mg/m^2{\cdot}h$ respectively, and the wallpapers of 25 satisfied emission standard. TVOC emission factor appeared in order of the concentration of PVC, natural, and Non-PVC wallpaper, while HCHO was detected very low concentration without relation to wallpaper sort. The paraffin hydrocarbons appeared to be the most contributable class of hydrocarbons in terms of their concentrations, followed by aromatics, and olefins, halogenated hydrocarbons was not detected. PVC wallpapers plentifully emitted TVOC above other wallpapers, and toluene was showed higher concentration of 10 times than natural wallpaper. In addition to, emission factor according to elapse was gradually decreased. 본 연구는 벽지 종류 및 방출기간에 따른 방출농도특성을 알아보고자 소형챔버법으로 방출시험을 수행하였다. 방출시험을 통해 측정 분석된 TVOC와 HCHO의 평균농도는 각각 $1.1mg/m^2{\cdot}h$, $0.01mg/m^2{\cdot}h$로 나타났으며, 25개 벽지 모두 현 방출기준을 만족하였다. TVOC 방출농도를 보면 PVC 벽지, 천연 벽지, Non-PVC 벽지 순으로 나타났으며, HCHO는 벽지 종류에 상관없이 아주 낮은 농도로 검출되었다. 정성된 45종 개별 VOC에 대한 성분별 기여도순을 보면 파라핀계 탄화수소, 방향족 탄화수소, 올레핀계 탄화수소였으며, 그 중 파라핀계 탄화수소는 90% 이상의 기여율을 보였으며, 독성이 강한 할로겐화 탄화수소는 검출되지 않았다. PVC 벽지는 다른 벽지에 비해 방출량이 많았으며, 톨루엔은 천연벽지 보다 10배 정도 높은 농도를 보였다. 한편, 방출시간 경과에 따른 방출농도는 점차적으로 감소하는 경향을 보여주었다.
