〔報告〕津波被災紙資料におけるATP＋AMP拭き取り検査の活用 [in Japanese] Application of ATP＋AMP Swab Test for Paper Documents Damaged by Tsunami [in Japanese]
Access this Article
Paper documents damaged by the tsunami that accompanied the Great East Japan Earthquake have been treated in Iwate Prefecture Museum since April 2011. However, it is difficult to confirm whether the deteriorating factors,such as fungus and bacteria,have been removed from the treated paper documents or not. ATP (adenosine triphosphate)＋ AMP (adenosine monophosphate)swab test method used in food hygiene field is a method for quickly measuring the degree of cleanliness. In order to evaluate the degree of the biological deteriorating factors of paper documents damaged by tsunami, ATP ＋ AMP swab test was applied for research on the tsunamidamaged paper documents in Iwate Prefecture Museum. In addition, microorganisms of dirt, such as soil and sand,which were collected from the paper documents were detected using cultivation. As a result,it was found that the degree of biological deteriorating factors of the paper documents declined after they were treated by removal of dirt with water, sterilization using sodium hypochlorite and dechlorination with water. Although mold growth was observed on dirt collected from an untreated document,there was no mold growth on dirt collected from a document washed with water. The result showed that the conservation method taken in Iwate Prefecture Museum is effective for the sterilization of paper documents damaged by tsunami. Further case studies are required in order to verify the effectiveness of ATP＋AMP swab test method on cultural properties.
