Objectives: This study was conducted to provide scientific and effective information on phytoncides, which areassociated with forest healing, and to activate recreational forests. Methods: The target sites were natural recreation forests, a forest park and an arboretum, and the control siteswere three urban parks. The samples were collected at a volume of 6.0 L and a flow rate of 0.1 L/min for onehour using a low volume pump and the solid adsorbent sampling method. The phytoncide compounds adsorbedin the Tenax TA tube were analyzed by a automatic heat desorption unit and GC-MS. Results: By type of recreational forest, the annual concentrations of phytoncide (monoterpene) for the forest parkshowed the highest concentration with 1.450 μg/m3, while those for the arboretum showed the lowestconcentration at 0.892 μg/m3, and thus the concentration of the forest park was approximately 1.6 times higherthan the arboretum. The season showing the highest concentration of phytoncides was summer (June) and theforest park was the highest among the recreational forests. The concentrations of major components forphytoncide showed in descending order: α-pinene, β-pinene, camphene, 3-carene and limonene. The seasonalconcentration of α-pinene, camphene and β-pinene by type of recreational forest increased in April, which ischaracterized by low temperature and humidity, and the seasonal concentration of camphene decreased withhigher humidity. The meteorological factors which had the high correlation with the concentration of totalterpene were temperature and humidity. CO2 and O2 showed an inverse correlation. Conclusion: The major components of phytoncide were α-pinene, β-pinene, camphene, 3-carene and limonenein descending order of concentration. Further and systematic study on the chemical nature of individualphytoncides, and on the effect of phytoncides on humans needs to be performed.
