Comparison of characteristics of anthropogenic volatile organic compounds (AVOC), biogenic volatile organic compounds (BOVC), and weather environment in forest, urban forest and urban
Introduction<br /> This study was conducted to scientifically identify the trends of healing factor in forests, urban forests, and urban areas to help people choose leisure activities.<br /> <br /> Method<br /> From 2019 to 2020, 30 kinds of biogenic volatile organic compounds (BVOCs), 5 kinds of anthropogenic volatile organic compounds (AVOCs), including toluene, and 3 kinds of weather conditions(temperature, humidity, wind speed) were analyzed at forest welfare facilities such as the National Forest Healing Center (MH: Masil Healing Forest Road, MD: Moon Drami Road), urban forest (SF: Seoul Forest), and urban (GS: Gwanghwamun Square). Weather measurements were made from a.m.8 to p.m.18 using MWM-P5 and analyzed using GC/Mass-TD (thermal desorption system) of BVOCs and AVOCs.<br /> <br /> Result<br /> The number of BVOCs generated was the highest at 254.73pptv at the MH, followed by 105.64pptv at the SF, 91.65 pptv at MD and 44.35pptv at the GS. AVOCs were the highest at 3.89ppbv in the GS, followed by 2.40ppbv in SF, 0.44ppbv in MH and 0.43ppbv in MD. The discomfort index(temperature humidity index : THI), calculated by temperature and humidity, was lower in forests than in urban areas. On average, the wind speed was higher in the order of the GS, SF, MD, MH.<br /> <br /> Conclusion<br /> Forests had higher BVOCs than urban, and AVOCs on average were lower. Also, Forests maintained a more pleasant weather environment than urban areas. The difference in AVOCs appears to be the result of tree species and location. BVOCs appear to have been measured high in heavy traffic urban areas, and the weather environment is believed to be the result of differences in the level of crown densities caused by plants. Through this study, we found that forests are better in terms of air quality and comfort than in urban areas. This can be used as a standard for choosing leisure activities in anticipation of forest healing effects. Keywords: Human health and well-being ID: 3483887
