Abstract
We aimed to understand the correlation between the microclimate environment within a forest and NVOC (Natural volatile organic compounds) concentration and the concentration of NVOC more efficiently through the prediction model method. In this study, 380 samples were collected and analyzed to examine the characteristics of NVOC emitted from a birch forest. NVOC were analyzed in May and July 2019, and measurements were performed at three different locations. Using a pump and stainless-steel tube filled with Tenax-TA, 9 L of NVOC was collected at a speed of 150 mL/h. The analysis of NVOC composition in the forest showed that it comprised α-pinene 27% and camphor 10%. Evaluation of the correlation between the NVOC concentration and the microclimate in the forests showed that the concentration increased markedly with the increase in temperature and humidity, and the concentration decreased with the increase in wind velocity. Nineteen substances in total including α-pinene and β-pinene were detected at high concentrations during the sunset. The results of the study site analysis presented a significant regression model with a R2 as high as 60.1%, confirming that the regression model of the concentration prediction of NVOC in birch forest has significant explanatory power.
Highlights
People have comfortable lives with industrialization and urbanization, but paradoxically are more exposed to many stressful environments as their urban lives become more advanced
The study is a birch forest located in the wondae-ri Betula platyphylla var. japonica forest, a trees planted in 138 ha
To achieve sustainable development of white birch forests, this study was conducted to identify the potential of these forests as healing spaces with forest value
Summary
People have comfortable lives with industrialization and urbanization, but paradoxically are more exposed to many stressful environments as their urban lives become more advanced. Exposure to stressful environments such as noise, fear of accidents, effects of environmental pollution, and complex lifestyle in urban areas can affect an individual’s mental and physical health and may cause social problems [1,2]. In a survey conducted by the Korea Centers for Disease Control and Prevention Air pollution is one of the reasons for causing stress in the urban environment and chronic diseases, which contains anthropogenic volatile organic compounds (AVOC) as its main factors. The existence of AVOC within the big cities’ atmosphere environment have been emitted through vehicles, architectural materials, and industrial facilities.
