Abstract

Anoxic treatments using argon and nitrogen gas in controlled atmospheres have been used as a alternative to methyl bromide for insect disinfection in museums. Anoxic chamber system was manufactured and installed at The National Folk Museum of Korea for the first time in Korea. The internal capacity of anoxic chamber is 0.5m3 in which is able to use argon, nitrogen and carbon dioxide gas. This system is equipped with oxygen concentration, temperature and ralative humidity control devices and automatically controlled oxygen concentration from 0.01 to 20%, temperature from 10 to $50^{\circ}C$ and relative humidity 30 to 80%. To control the oxygen concentration, anoxic chamber system is adopted semi-dynamic method which supplies mixture of humidified gas and dry gas whenever oxygen concentration in chamber becomes higher than setting value. It has kept regularly oxygen concentration, temperature and relative humidity for 20 days using argon gas. To evaluate the disinfection of cigarette beetle larvae and adults and varied carpet beetle larvae, the anoxic chamber system maintained 0.01% of oxygen concentration, $25^{\circ}C$ in temperature and 50% in relative humidity for 30 days. Cigarette beetle larvae were killed in 7 days and adults in 3~5 days. And varied carpet beetle larvae were killed in 3 days. It reaches the conclusion form the evaluation this anoxic chamber system can be used to develop anoxic treatment as an alternative of methyl bromide for insect disinfection of infested cultural properties in museums.

박물관에서 문화재 해충의 살충을 위해 사용되어 온 메틸브로마이드는 오존층 파괴물질로써 2015년 사용이 금지됨에 따라 대체법으로써 아르곤이나 질소를 사용한 저산소 농도 살충법이 도입되었다. 국립민속박물관에서는 국내 최초로 저산소 농도 살충법의 적용이 가능한 저산소 농도 살충 챔버 시스템을 시제작하여 설치하였다. 저산소 농도 살충 챔버 시스템은 챔버 내부 용량이 $0.5m^3$이며, 아르곤, 질소, 이산소탄소의 사용이 가능하다. 이 시스템은 산소 농도 0.01~20%, 온도 $10{\sim}50^{\circ}C$, 습도 30~80%를 자동적으로 제어가 가능하며, 산소 농도 제어는 설정값 이상으로 상승할 때마다 가습 가스와 건조 가스를 혼합하여 주입하는 방법을 채택하였다. 시운전을 위해 30일 동안 가동 결과, 산소 농도, 온도 및 습도가 일정하게 유지되었다. 그리고 권연벌레 애벌레와 성충, 애알락수시렁이 애벌레 대해 아르곤 가스를 사용하여 산소 농도 0.01%, 온도 $25^{\circ}C$ 및 습도 50% 환경에서 살충 성능을 평가한 결과, 권연벌레 성충은 3~5일, 애벌레는 7일, 애알락수시렁이 애벌레는 3일이 소요되어, 시제작된 저산소 농도 살충 챔버 시스템의 살충 성능을 확인할 수 있었다. 평가 결과로부터 저산소 농도 살충 챔버 시스템은 박물관에서 메틸브로마이드 대체법인 저산소 농도 살충법의 기술을 개발하는데 충분히 활용이 가능함을 확인하였다.
