소나무 숲의 계절별 NVOC농도변화와 물리환경과의 관계

다국어 초록 (Multilingual Abstract)

This research has been conducted with the purpose of scientifically investigating the correlation between NVOC concentration of Daegwallyeong Pinus densiflora forest and its physical environmental factors. To fulfill this research, the investigation has been carried out by separating a year starting from December of 2012 to November of 2013 into 11 seasonal divisions. Each measurement consisted of 9L of pine forest air in 150ml/min flow velocity according to sunrise, culmination, sunset, totalling 143 sampling. In order to minimize the margin of error, two separate tubes have been used in same location and the average of analyzed measurement has been used. The collected NVOC substances were analyzed using HS-SPME procedure, then GC-MS analysis method.
The seasonal NVOC concentration of Daegwallyeong Pinus densiflora forest showed D-Limonene as the highest concentration during the winter but α-pinene as the highest concentration during the spring. Both summer and fall showed α-pinene as the highest concentration just as the spring. The NVOC composition distribution ratio showed differences every month, thus, it is expected that the seasonal physical environment affected the characteristics of the NVOC substances.
After comparing the correlation of NVOC concentration and its physical environment, majority of substances showed higher concentration when temperature, dew point, and humidity was higher; whereas the concentration dropped when the wind velocity rose. In order to verify such findings, the relationship between seasonal NVOC concentration and physical environment has been measured by comparing the measurement in hourly basis in a day of summer when the highest concentration is emitted. However, because of the different wind velocity which is a significant physical environment factor, NVOC has been analyzed every 10 minutes from 8pm to 9pm which showed highest concentration emission using specially manufactured pump. As a result, distinct correlation of NVOC concentration rises and drops has been found that with higher temperature, humidity, and dew point, the concentration rises whereas with higher wind velocity, it drops.
The researches in the past have been questioned of its accuracy due to the wash away of substance filling. However, in this research only disposable tubes have been used in order to minimize the margin of error. Currently, such method of research is insufficient, proposing more future research to have clear finding on NVOC concentration in the forest.
The data collected in this research can be used as a beneficial information in regard to health and outdoor leisure activities of people, and also provide more new understandings of forest and construction of healing forest, recreational forest, and urban forest for the people.
