Abstract
본 연구는 벽지 종류 및 방출기간에 따른 방출농도특성을 알아보고자 소형챔버법으로 방출시 험을 수행하였다. 방출시험을 통해 측정 분석된 TVOC와 HCHO의 평균농도는 각각 1.1 mg/m2·h,0.01 mg/m2·h로 나타났으며, 25개 벽지 모두 현 방출기준을 만족하였다. TVOC 방출농도를 보면 PVC벽지, 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, 독성 이 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.
