Abstract

The present study was performed to compare healing environments among five tree species in the Kasuya Research Forest of Kyushu University. Measurements of forest stand-specific natural volatile organic compound (NVOC) concentrations and predicted mean vote (PMV) and predicted percentage of dissatisfied (PPD) indexes were performed simultaneously in the same region. Samplings were performed using Tenax TA-filled tubes and mini pumps to collect NVOCs in the forest air. The collected NVOCs were analyzed using gas chromatography-mass spectrometry. In addition, measurements of physical features of the forest environment (including temperature, humidity, wind velocity, and illumination intensity) were performed at a time interval of 1 min. Eucalyptus gomphocephala emitted the highest concentration of NVOCs (3.13 ng/m3). Thermal comfort was the highest in E. saligna community (PMV: -0.1; PPD: 6.9%), which revealed that Eucalyptus species has an excellent healing environment. The data obtained from this study may be used as beneficial information for citizens, who in turn will view the value of forest in a new perspective.
