“…It is possible therefore that these species may be lost to condensed water during sample collection or during the transfer of collected samples between wet and dry sample tubes. In addition, it is known that significant errors associated with the quantification of reactive and oxygenated compounds can arise (Larsen et al, 1997). The oxygenated species found here were not quantified due to uncertainty in their quantitative transfer.…”

Abstract. The biogenic volatile organic compound (BVOC) composition of ambient air at a rural field site near Djougou, Benin has been studied as part of the AMMA (African Monsoon Multidisciplinary Analysis) project. Ambient air was sampled during day and night during the period 2 June 2006 to 13 June 2006. Gas samples from within the forest canopy and from branch and cuvette enclosure systems for four vegetation species were also obtained and emissions flux estimates made. All samples were analysed for the presence of isoprene, monoterpenes and sesquiterpenes by either gas chromatography-time of flight mass spectrometry (GC-TOF/MS) or comprehensive gas chromatography-time of flight mass spectrometry (GCxGC-TOF/MS). Concentrations of isoprene ranged from a few tens of pptV to in excess of 3000 pptV. Similar concentration ranges for certain monoterpenes were also observed. Limonene was seen at a maximum concentration in ambient air of 5000 pptV. The combination of leaf-level observations and direct analysis of dried vegetation samples suggests that emissions of terpene species from indigenous species are unlikely to account for the unexpectedly high ambient concentrations of monoterpenes. Leaf scale emission measurements and biological sample analysis indicated that Anacardium occidentale, a non-native crop species found throughout the tropics, was the dominant source of monoterpenes at this location. These preliminary findings suggest that activities involving species replacement have potential implications for the chemistry of the African troposphere that have not been widely considered previously.

“…No in-line ozone scrubber was used, so it is acknowledged that there may have been uncharacterised losses of the reactive VOC from oxidation by ozone during the sampling and/or other on-tube interactions/rearrangements (Larsen et al, 1997;Helmig, 1997;Pollmann et al, 2005). The co-current collection of these samples (which occurred on 2 days out of the 4 week campaign) was only for the purposes of a spot inter-comparison against the continuous PTR-MS data, and to provide an indication of speciation between α-pinene and β-pinene, which the PTR-MS cannot distinguish.…”

“…Some of the monoterpenes are easily isomerized in stainless-steel cans, excessively heated metal transfer lines, and during storage or thermal desorption from adsorbent sampling traps. Therefore measured ratios of monoterpene emissions may be altered from their actual emission ratio (Larsen et al, 1997). For instance, -pinene and -pinene can be isomerized during analysis, forming camphene and possibly other monoterpenes in the process.…”

“…This may partially account for its absence or low levels in enclosure or rural air measurements (Larsen et al, 1997). The sesquiterpene -caryophyllene is often undetected unless O is scrubbed from enclosure purge air (Helmig, 1997).…”
