Research of Monoterpenes Content in the Atmosphere of Forest

Abstract

[The biogenic emission of the atmospheric volatile organic compounds (VOCs) from the forests is dominated by monoterpenes. This study investigated the changes in the concentration of monoterpenes distributed in various types of forest near the Gangwon Nature Environment Research Park, Hongcheon, Gangwon Province, Korea. Samples were collected from the three sites of different types of forest, including coniferous, broadleaved and mixed forests. Additionally, the seasonal and daily changes of monoterpene compounds were monitored. Our results found the several types of monoterpene such as α-pinene, β-pinene, camphene, d-limonene, p-cymene and α-terpinene. The highest total concentration of terpene compounds was observed in the coniferous forest. For the summer season, the total concentration of terpene compounds was highest in coniferous and mixed forests, and that was also highest in broad-leaved forest for the autumn.]
