Abstract

Large scale anoxic chamber system(volume $28m^3$) was developed and installed at The National Folk Museum of Korea for the first time in Korea. In order to get optimal anoxic treatment condition, we compared the disinfection of adults, larvae and eggs of cigarette beetles using nitrogen and argon. The time for complete disinfection of cigarette beetles in pine wooden blocks exposed to nitrogen at oxygen concentration 0.01% and 50% in relative humidity were 15 days at $20^{\circ}C$, 10 days at $25^{\circ}C$, and 7 days $30^{\circ}C$. Time were 10 days at $20^{\circ}C$, 7 days at $25^{\circ}C$, and 5 days $30^{\circ}C$ in argon anoxic atmosphere. From the mortality of cigarette beetles, optimal disinfection condition was oxygen concentration 0.01%, $25^{\circ}C$ in temperature, 50% in relative humidity and exposure time 21 days at nitrogen atmosphere. And when large scale anoxic chamber system was supplied nitrogen by nitrogen generator for anoxic treatment of many collections or large collections, it could be operated stably. To verify optimal disinfection condition, museum insects(adults, larvae, pupae and eggs of cigarette beetles in pine wooden blocks, cotton fabrics and Korean paper book, adults and larvae of drugstore beetles in pine wooden blocks, cotton fabrics and Korean paper book, larvae of varied carpet beetles in pine wooden block and silk fabrics, adults and larvae of hide beetles and adults of rice weevils in breeding boxes) which exposed at optimal disinfection condition, were completely killed.

질소와 아르곤을 사용한 대용량 저산소 농도 살충 챔버 시스템(내용적 $28m^3$)을 이용하여 박물관에서 발견되는 문화재 해충에 대한 살충력 및 운용성을 평가하였다. 질소 환경에서 저산소 농도 살충처리를 하였을 때 산소 농도 0.01%, 습도 50%의 환경하에서 나무 블록 속의 권연벌레 성충, 애벌레, 알의 완전 살충에는 $20^{\circ}C$ 15일, $25^{\circ}C$ 10일, $30^{\circ}C$ 7일이 소요되었다. 아르곤 환경에서는 $20^{\circ}C$ 10일, $25^{\circ}C$ 7일, $30^{\circ}C$ 5일이 소요되어, 질소 저산소 농도 살충처리는 아르곤에 비해 살충시간이 50% 더 소요되었다. 살충 시험 결과로부터 최적 살충 조건은 산소 농도 0.01%, 온도 $25^{\circ}C$, 습도 50%, 살충시간 21일로, 질소발생기로 대량의 질소를 자동 공급이 가능한 질소 저산소 농도 살충법은 대용량 저산소 농도 살충 챔버 시스템의 안정적인 운용이 가능한 방법으로 평가되었다. 최적 살충 조건에서 나무 블록, 면직물, 견직물, 한지 서적에 넣은 권연벌레의 알, 애벌레, 번데기, 성충, 인삼벌레의 성충, 애벌레, 알락수시렁이 애벌레 및 사육함의 암검은수시렁이의 애벌레, 성충 그리고 쌀바구미 성충은 100% 살충이 되었다. 본 연구를 통해 대용량 저산소 농도 살충 챔버 시스템은 질소 저산소 농도 살충법으로 박물관 발생 문화재 해충의 완전 살충과 원활한 운용이 가능할 것으로 판단되었다.
