This study investigated the relation between formaldehyde emissions and fungal growth on plywood materials. In order to find out the effect of formaldehyde emissions on the growth of fungi species, four species, such as aspergillus, cladosporium, penicillium and rhzopus were grown on the surface of 11 different materials of which formaldehyde emission rate were tested before the their culture. From the results, it is found that formaldehyde emission rats significantly affect the biological activity of fungal spores on the materials. The spores are very active below about 20μg/(m^2h), formaldehyde emission rate. The activity of fungal species, however, becomes to weak at about 30μg/(m^2h), and then they are inactivated over about 560μg/(m^2h). This result demonstrates that fungal growth on the wooden materials depends on not only indoor air environmental conditions but also formaldehyde emissions rate.
