Abstract

Objectives: This study was conducted to provide scientific and effective information on phytoncides, which are
associated 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 sites
were three urban parks. The samples were collected at a volume of 6.0 L and a flow rate of 0.1 L/min for one
hour using a low volume pump and the solid adsorbent sampling method. The phytoncide compounds adsorbed
in 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 park
showed the highest concentration with 1.450 μg/m3, while those for the arboretum showed the lowest
concentration at 0.892 μg/m3, and thus the concentration of the forest park was approximately 1.6 times higher
than the arboretum. The season showing the highest concentration of phytoncides was summer (June) and the
forest park was the highest among the recreational forests. The concentrations of major components for
phytoncide showed in descending order: α-pinene, β-pinene, camphene, 3-carene and limonene. The seasonal
concentration of α-pinene, camphene and β-pinene by type of recreational forest increased in April, which is
characterized by low temperature and humidity, and the seasonal concentration of camphene decreased with
higher humidity. The meteorological factors which had the high correlation with the concentration of total
terpene 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 limonene
in descending order of concentration. Further and systematic study on the chemical nature of individual
phytoncides, and on the effect of phytoncides on humans needs to be performed.
