초록
본 연구의 목적은 공기감염성 가축질병 유발의 주요 인자인 부유 세균 및 바이러스 등의 생물학상 인자들에 대한 유형별 공기청정기의 제균 효과를 비교 평가하는 데 있다. 시료 채취 장비에 대한 포집 성능 평가에서는 MS2 바이러스와 Pseudomonas fluorescens 모두 Button sampler보다는 Biosampler에 의한 채취 효율이 유의하게 높았다 (p<0.05). 공기청정기 유형 및 시료채취 방법에 관계없이 MS2 바이러스의 경우 초기 농도 대비 가동 후 5분에 50% 이상, 15분에 70% 이상, 30분에 80% 이상, 그리고 마지막 측정 시점인 60분에는 90% 이상의 제거 효율을 보이는 것으로 나타났다. P. fluorescens 세균의 경우 초기 농도 대비 가동 후 5분에 45% 이상, 15분에 50% 이상, 30분에 70% 이상, 그리고 마지막 측정 시점인 60분에는 75% 이상의 제거 효율을 보이는 것으로 나타났다. 유형별 공기청정기의 상대적 제균 효율을 비교해 보면 MS2 바이러스의 경우 이온 발생 방식>전기 집진 방식>습식 방식>건조 방식, P. fluorescens 세균의 경우 전기 집진 방식>이온 발생 방식>건조 방식>습식 방식의 순서로 조사되었다.
Abstract
The objective of this study is to evaluate reduction efficiency of various air purifiers on airborne microorganism causing air infected animal disease according to sample collection method. Collection efficiencies of MS2 virus and Pseudomonas fluorescens by biosampler was significantly higher than those by button sampler (p<0.05). Regardless of types of air purifier and sample collection method, temporal reduction efficiencies of MS2 virus and P. fluorescens compared to initial background concentration were >50% and >45% on 5 minutes, >70% and >50% on 15 minutes, >80% and >70% on 30 minutes and >90% and >75% on 60 minutes after operating air purifier, respectively. The air purifier of ionizer type showed the highest reduction efficiency on MS2 virus followed by air purifier of electronic precipitation, water filter and dry filter while the reduction efficiency of air purifier on P. fluorescens was highest in the electronic precipitation type followed by ionizer type, dry filter type and water filter type (p<0.05). Based on the results obtained from this study, temporal reduction efficiency of air purifier on MS2 virus was relatively higher than P. fluorescens.
