VOCs (Volatile Organic Compounds) are hydrocarbon compounds that easily volatilize into the atmosphere in gas form. They are classified into AVOCs (Anthropogenic Volatile Organic Compounds), emitted from anthropogenic sources, and BVOCs (Biogenic Volatile Organic Compounds), released from natural sources such as trees and herbaceous plants. Phytoncides, a component of BVOCs, are known for their beneficial effects on human health as forest therapy substances. However, from an atmospheric chemistry perspective, BVOCs are highly reactive and contribute to ozone (O₃) formation through photochemical reactions with nitrogen oxides (NOₓ). BVOCs are categorized into isoprene (C₅H₈), monoterpenes (C₁₀H₁₆), sesquiterpenes (C₁₅Hₓ), other reactive VOCs (ORVOCs, CₓHᵧOₓ), and other VOCs (OVOCs). The global emissions of BVOCs are estimated at approximately 1007 TgC/year, which is reported to be 7 to 10 times higher than AVOCs. Measurements were conducted for over two weeks using PTR-ToF-MS (Proton-Transfer-Reaction Time-of-Flight Mass Spectrometer) equipment on the Kangwon National University campus (in December 2023 and April 2024) and at the Gangwon Regional Air Environment Research Center (in June 2024). The study analyzed seasonal trends in BVOCs concentrations, their relationship with meteorological factors, and the correlation with ozone (O₃) concentrations in Chuncheon City. As a result of performing one-way ANOVA to analyze the seasonal differences in BVOCs concentrations, the concentration of isoprene showed a significant difference depending on the season (F₂, 1263 = 989.9, p < 0.001), and pinene also showed a significant difference (F₂, 1263 = 267, p < 0.001).
