Objectives: An objective of this study is to apply a thermal image camera which shows various color according to temperature of indoor surface for estimating concentration of airborne fungi.
Materials and Methods: While wall temperature were monitored by applying the thermal image camera, airborne bacteria as well as air temperature and relative humidity have been measured in lecture room and toilet of university for seven months.
Results: Based on the results obtained from this study, the ranges of temperature and airborne fungi concentration were 20∼24℃ and 20∼400 cfu/m3 for red image, 17.5∼20℃ and 35∼150 cfu/m3 for orange image, 15.5∼17.5℃ and 25∼650 cfu/m3 for sky-blue image, and 13.5∼15.5℃ and 50∼200 cfu/m3 for blue image, respectively. The color of indoor surface taken shot by thermal image camera showed consistent trend with temperature of indoor surface. There is, however, little correlation between color of indoor surface and airborne fungi concentration(p>0.05). Among environmental factors, relative humidity in indoor air showed a significant relationship with airborne fungi concentration(p<0.05).
Conclusions: The more measurement data for proving statistically an association between color of indoor surface and airborne fungi concentration should be provided to easily estimate indoor level of airborne fungi.
