Abstract

Smoke toxicity is the test for the toxicity evaluation of smoke and hazardous gas, caused by combustion of building materials and finishing materials. Smoke toxicity can be evaluated by the mean incapacitation time of mice. This test result can be influenced by the health status of mice and test condition. In acute inhalation toxicity test of hazardous gas, no typical clinical findings and histopathologic abnormalities were observed. Tracheitis and bronchitis as well as acute lung inflammation around terminal bronchiole in some mouse of the highest dose group. Through this study, we established the method for inhalation toxicity test of hazardous gas as well as the SOP of inhalation toxicity test. However, in the future studies, the concentration control methods for inhalation technologies on hazardous gas will be needed to improve continuously and also further studies on other gas inhalation toxicity will be needed to conduct.

우리나라에서 건축물 내장재의 화재안전성능은 국토해양부 고시 제2011-39호에 의한 평가방법에 의해 불연성시험(KS F ISO 1182), 열방출률시험(KS F ISO 5660) 및 가스유해성시험(KSF 2271)을 실시하여 그 결과로서 분류하도록 되어 있다. 그 중 연기 및 연소독성가스에 대한 시험인 가스 유해성 시험은, 건축재료 및 내장재의 연소시 발생하는 가스의 유해성을 마우스의 평균 행동정지시간으로 측정하는 방법으로 사용하여 왔다. 이 중 연소 독성가스 4종(HCl, HF, HCN, $SO_2$) 흡입독성시험방법의 확립을 위하여 ICR계 mouse와 전신흡입노출장치를 이용하여, 독성가스 노출 및 병리검사를 수행하였다. 그 결과 호흡기관지와 가까운 폐포에서 대식세포(Macrophage)의 침윤을 유발하는 것으로 나타났고, 4종의 물질에 대한 조직의 병리검사로 전체적으로 충혈과 울혈은 확인되었다. 조직 중 폐와 신장에서 조직손상이 심하였고, 물질로는 HCN이 가장 많은 병리소견을 보였다.
