Abstract

With the development of nanotechnology, the amount of nanomaterials increases and the problems of environment and the toxic property associated with it have become a social problem. But regulations and laws of nanomaterials have not yet been established. The purpose of this study is to utilize as the database of safety guidelines for research activities' workers associated with nanomaterials to conduct a behavior evaluation of aluminium oxide, which is most widely used in thirteen kinds of WPMN manufactured nanomaterials in the country. The experiment proceeds in the chamber reduced to 1/6 size of the actual laboratory, the test method was performed in NIOSH 0500. As the results of the study, the mass concentration was in inverse proportion to the particle size of the nanomaterials. And the mass concentration during the operation of ventilation equipment was reduced to about 1/8 times. In the future, it can be utilized as the database of safety guidelines for research activities' workers associated with nanomaterials. However, in order to increase the reliability of the study, the experiment of the mass concentration by particle size and Condensation Particle Counters will be needed additionally.

나노기술이 발전함에 따라 나노물질의 사용량이 증가하고, 그에 따른 환경 및 인체 유해성 문제가 사회적 이슈로 대두되고 있으나 나노물질에 대한 규제나 법규는 아직 제정되어 있지 않다. 이에 본 연구에서는 WPMN에서 지정한 제조나노물질 13종 중 국내에서 가장 많이 사용되고 있는 물질인 aluminium oxide의 거동평가를 실시하여 연구활동종사자들을 위한 안전지침의 기초 자료로 활용하고자 하였다. 실험은 실제 연구실을 1/6의 크기로 축소하여 제작한 chamber에서 진행되며, NIOSH method 0500에 준하여 질량농도를 측정하였다. 연구 결과 질량 농도는 물질의 입자 크기에 반비례하는 것으로 나타났으며, 환기 설비의 작동만으로 질량농도가 약 1/8배까지 감소하는 것을 확인 할 수 있었다. 본 연구를 향후 나노물질 관련 연구활동종사자를 위한 안전지침의 기초자료로 활용할 수 있을 것으로 보이나, 연구의 신뢰도를 높이기 위해 입경에 따른 질량농도, 수농도 측정등의 실험이 필요할 것으로 사료된다.
