Abstract
Some of tree species (ex. Eucalyptus glob ulus Labill. and Pinus pinaster Aiton) are emitting BVOCs which are biogenic volatile organic compounds. Because of them volatile properties they might act as potential fuel during forest fire’s propagation, particularly under extreme atmospheric conditions. In order to optimize the experimental conditions, numerous determinations were carried out studying the release of five major monoterpenoids (α-pinene, β-pinene, thymol, limonene and 1,8-cineole) from leaves of tree species, while maximum selectivity and efficiency were achieved using activated carbon and PDMS/DVB fiber as sorbent phases for HS-BAμE and HSSPME, respectively. A new analytical approach is proposed for monitoring biogenic volatile organic compounds (BVOCs) by combining headspace bar adsorptive microextraction (HS‐BAμE) with gas chromatography–mass spectrometry (GC‐MS). The HS‐BAμE methodology was developed, optimized, validated and applied for the analysis of BVOCs emitted and compared with headspace solid chase microextraction (HS‐SPME), commonly accepted as a reference technique [3]. Under optimized experimental conditions, both methodologies showed similar profiling and proportional responses, although the latter present a higher sensitivity in the analytical configuration used. For the five monoterpenoids studied, acceptable detection limits and suitable linear dynamic ranges were achieved. In addition to other advantages BAμE technology has proven to be an effective and promising analytical alternative for monitoring BVOCs, given its great simplicity, easy handling and low cost.
