측정방법에 따른 유물전시관 기획전시실 내 알데하이드 농도 분포 특성 비교

Comparison of Aldehydes Concentrations Characteristics According to Measurement Methods in Temporary Exhibition Hall

본 연구에서는 기획전시실을 대상으로 능동시료채취(Active type)와 확산형 시료채취(Passive type) 방법에 의한 전시실 내 외 알데하이드의 연중, 계절별 농도를 조사하고 측정방법에 따른 농도 비교를 통해 측정방법 간의 상관성을 비교하였다. 그 결과, Active type에 의한 전시실의 총알데하이드는 Passive type 보다 6.4배 높았다. 가장 높은 농도로 조사된 폼알데하이드는 여름철 농도가 가장 높았고 환경부 전시시설 기준을 초과하였다. 폼알데하이드의 연평균 I/O비는 5.4이었고 아세트알데하이드는 1.9로 알데하이드는 기획전시실 내부에서 다량 발생함을 확인할 수 있었다. 두 방법 간의 폼알데하이드 상관계수와 t-검정 결과, 강한 양의 선형관계임을 확인할 수 있었다.

In this study, the annual and seasonal concentrations of aldehydes was measured using the active type and passive type method in the temporary exhibition hall and outdoor air. It was compared with the correlation between the methods according the comparison of methods to measured concentrations. As a results, the ${\Sigma}$ aldehydes in exhibition hall by the active type was higher than 6.4 times by passive type. The formaldehyde was exceeded standards in exhibition facilities of the Ministry of Environment. It was the highest concentrations in summer. Annual I/O ratio of formaldehyde was 5.4 and acetaldehyde was 1.9, it was confirmed that a large amount occurs in the temporary exhibition hall. The results of the correlation coefficient and the t-test of formaldehyde were a strong positive linear relationship between the active type and the passive type.
