Comparison of Seasonal and Diurnal Concentration Profiles of BVOCs in Coniferous and Deciduous Forests

Ambient atmospheric concentrations of isoprene and monoterpenes were measured at two forest sites, one deciduous coniferous, over the year 2022. Both sites in a regional area sampled monthly between April September. The samples taken using sorbent tubes analyzed with thermal desorption–gas chromatography–mass spectrometry. highest determined August both sites. While is most abundant compound an average concentration 5.59 µg m−3 August, α-pinene β-pinene dominate throughout coniferous also (3.44 1.51 m−3). Because other (camphene, sabinene, 3-carene, p-cymene limonene) are emitted significant amounts, total higher (7.96 August) comparison to (6.08 Regarding detected forest, sabinene dominant monoterpene addition sometimes present (July) or equal (August) concentrations. seasonal diurnal all correlate very well each An exception profile similar isoprene.
