Abstract

In this study, the experiment to confirm the risks of particulate material was carried out as a precedent study for developing the toxicity evaluation method of combustion products including the toxicity of particulate material. In the experiment, the test result of filtering and exposing particulate material among combustion products and that of exposing combustion products including particulate material were compared and analyzed by analyzing changes in average movement stop time according to the installation of Membrane filter between the stirring box and test box through the gas toxicity test of the same specimen to filter particulate material among combustion products. As the test result, in case of installing a filter, the average movement stop time of an experimental rat increased by up to 264% in case of lumber specimen and up to 179% in case of urethane specimen. Through such result, the necessity of identifying the toxicity of particulate material and carrying out quantitative toxicity test for particulate material was confirmed.

본 연구에서는 입자상 물질의 유해성을 포함하는 연소생성물 독성평가 기법의 개발을 위한 선행 연구로써, 입자상 물질의 위험성을 확인하기 위한 실험을 수행하였다. 실험은 동일 시료의 가스유해성 시험을 통하여 교반상자와 피검상자 사이 Membrane 필터 설치 유무에 따른 평균행동정지시간의 변화를 분석함으로써, 연소생성물 중 입자상 물질을 필터링하여 노출시킨 경우와 입자상 물질을 포함한 연소생성물을 노출시킨 경우의 시험 결과를 비교 분석하였다. 시험결과 필터 장착 시 실험용 쥐의 평균행동 정지시간이 목재 시료의 경우 최대 264% 증가하였으며, 우레탄 시료의 경우 최대 179% 증가함을 확인하였다. 이를 통해 입자상 물질의 유해성 및 이에 대한 정량적 독성평가의 필요성을 확인하였다.
