Abstract
Plants re-emit a fraction of assimilated carbon into the atmosphere as biogenic volatile organic compounds (BVOCs). BVOCs are a heterogeneous group of compounds that includes terpenes (isoprene, monoterpenes, sesquiterpnes) as well as alkanes, alkenes, alcohols, aldehydes, esters, ethers, acids. These compounds contribute to the formation of troposheric ozone (O3) and secondary organic aerosols (SOA) and thus can play an important role in the Earth global system. Recent studies have also emphasized that global warming will lead to important feedback between BVOC emissions and climate change. BVOC emissions are regulated by a range of biotic and abiotic factors and vary from species to species. The first aim of the thesis was to develop an innovative accelerated solid-phase dynamic extraction (ASPDE) technique for BVOC measurements. The second aim was to study the BVOC emissions of selected European common or/and poorly investigated tree species: Quercus robur (oak), Fraxinus excelsior (ash), Abies alba (silver fir), Pinus nigra supsp. laricio (black pine), Larix decidua (larch). Experiments were carried out at ambient conditions in Flanders (Belgium). This research provides information on BVOC measurement techniques as well as emission patterns and rates of BVOCs from aforementioned tree species. Moreover, seasonality and other factors influencing BVOC emissions are also explored. Overall, collected data contribute to BVOC emission databases and can be used for improving the estimation of regional and global BVOC budgets.
