| 1 | Analyses of BioVOCs variation related to vegetation predominance in the Natural Park of Ampezzo Dolomites, UNESCO world heritage area of Dolomites显示文摘The determination of emitted Biogenic Volatile Compounds (BioVOCs) profile via Field Air Analysis (FAA) - Solid Phase Micro Extraction (75 μm Carboxen/PDMS portable field sampler) was performed using GC-MS. The six sampling sites located in the Natural Park of Ampezzo Dolomites, part of the UNESCO's World Heritage List, are characterized by different predominating vegetation. The ubiquitous compound hexanal was chosen as internal standard, in order to compare the amounts of the different compound in the different sites. The main terpenes identified were α-pinene, β-pinene, δ-3-carene and d-limonene, while 1,8 cineole was the highest abundant oxygenated terpene. In the site next the national road a higher amount of benzene derivatives (benzene, toluene, o-xylene, p-xylene and ethylbenzene) were observed. In the site relatively close to the road a marked decrease of benzene derivatives was observed. In the sites close to conifers (i.e. Fir, Pine and Larch) the terpenic content observed was higher than in the site close to the mixed forest (mainly large-leaf and some conifers). Some terpenes were observed also in the high-quote meadow site, although of lower abundance than in the other sites. The highest abundance of terpenes was observed in the Pinus cembra (Swiss Pine) site. | Luca Raveane Francesco Tisato Ilena Isak Pietro Traldi | 2013 | Journal of Forestry Research2013，24，3： | 1 |
