| Research Abstract |
Study was done from five points of view as follows ; (1) study on monitoring method of fungous contamination in museums, (2) controlling environmental conditions by numerical simulation of air current, (3) less-chemical method for suppression of fungous growth, (4) actual survey of fungous contamination in museums, (5) collecting information of the effects by chemical biocides to human health.
Three portable samplers for counting air-borne fungi were studied in order to know repetitively reproducibility, residual of measuring, accuracy and reliability, respectively. Furthermore, correlation coefficient between three methods was obtained. All three samplers were not always stable in every suction volume and they were inclined to unstable in smaller suction volume. Suitable cultivation media should be selected considering the contamination level by fungi and it was found that MA medium was good for evaluate the fungous contamination level in the space close to outdoor like tumulus, and PDA medium was good in order to know the fungous contamination level in museums under air-conditioning.
Under this study, it was cleared that fungous growth were strongly affected by water content of the surface of media. In order to suppress the fungous growth, hydrophilic resins were tried to apply to soil for maintain the suitable water content on surface. Water content of soil surface was measured by infrared reflection method then it was found that water content was still high, but that the distribution of water content was small on the surface. Finally, it was thought that hydrophilic resin was good for not making dew point on the soil surface.
Actual investigation about fungous contamination in museums was performed and cleared that contamination in museums were still lower level than in residence. It was thought that measuring air-borne fungi was effective to find the actual growth of fungi in the room concerned.
