A complete description of the system is given by Paczkowski et al (). Charcoal filtered and humidified air was supplied to both arms of the olfactometer at a total constant flow of 400 ml/min, with each chamber receiving a flow of 40 ml/min from each side.…”

The eucalyptus weevil, Gonipterus platensis (Coleoptera, Curculionidae), is a major pest of eucalyptus plantations worldwide. To date, no pheromones have been identified for this species, despite their valuable potential as tools in monitoring or control strategies. Here we report the detection and identification of pheromones candidates of G. platensis. The weevil's volatile compounds were collected by solid phase micro extraction (SPME) and monolithic material sorption extraction (MMSE). Using Gas Chromatography coupled to Mass Spectrometry (GC/MS) analysis, eleven insect specific compounds were detected and identified: verbenene, cis‐verbenol, trans‐verbenol, verbenone, 2‐oxo‐1,8‐cineole, 9‐hydroxy‐1,8‐cineole, 2‐α‐hydroxy‐1,8‐cineole, 3‐oxo‐1,8‐cineole, 2‐β‐hydroxy‐1,8‐cineole, 3‐α‐hydroxy‐1,8‐cineole and 7‐hydroxy‐1,8‐cineole. Three of these compounds, verbenene, cis‐verbenol and trans‐verbenol, were shown to be male‐specific. Antennal sensitivity towards ten compounds emitted by G. platensis was detected using Gas Chromatography–Mass Spectrometry/Electroantennographic Detection (GC‐MS/EAD). Extracts from virgin males proved to be attractive to virgin females in olfactometer bioassays. Further behavioural bioassays showed that both virgin females and virgin males were attracted to the male‐specific compound cis‐verbenol and that virgin females were attracted to trans‐verbenol. Verbenone was attractive to mated females. Regarding 2‐α‐hydroxy‐1.8‐cineole and 2‐oxo‐1,8‐cineole, which are produced by both sexes, the alcohol was attractive to virgin males and both the alcohol and the ketone were repellant to mated females. This is, to our knowledge, the first identification of pheromones candidates in Gonipterus spp. and also the first evidence of cineole metabolites acting as semiochemicals.

“…During combustion, high emission rates of furfural have been reported in laboratory-based studies (Andreae and Merlet, 2001;Ciccioli et al, 2001). In a recent study, furfural was selected to be marker volatile compounds for early fire warning systems because it is emitted at high rates prior to ignition (Paczkowski et al, 2013). However, furfural concentrations are found to be low in the atmosphere aerosols downwind from wood combustion (Simoneit, 2002) and the few furfural measurements are available for air masses derived from biomass combustion.…”

Seasonal variability of daily particle mass and saccharides and furfural concentrations in atmospheric particulate matter in both coarse aerosols (diameter > 2.4 µm) and fine aerosols (diameter < 2.4 µm) was determined for a semi-urban area in the United Kingdom. Saccharides, which include levoglucosan, and furfural are derived from biomass burning and contribute to aerosol composition. This study examined the potential of saccharides and furfural as tracers for biomass combustion. High saccharide concentrations were observed in the autumn, but they did not show a high correlation with potassium expected in biomass smoke. These results may imply that the high saccharide concentrations are derived not only from biomass burning sources, but also from non-combustion sources, such as leaf decay. Significant seasonal variations were observed for saccharides and furfural species in fine atmospheric aerosols. Furfural is likely to be oxidized quickly in comparison with saccharides, so while saccharides such as levoglucosan are known to be fairly stable in the atmosphere, furfural could be transformed. Trajectory and factor analysis suggest that the saccharides may result from long-range transport, while furfural may be more influenced by the local sources possibly because of its shorter lifetime. This result may suggest it could give clues as to the age of biomass smoke.

“…The three high-priority VOCs, benzene, formaldehyde and naphthalene, have been applied in concentrations below, at and above the respective guideline values, and ethanol has been added as an interferent gas in much higher concentrations in order to simulate typical IAQ applications with background gases from, e.g., cleaning agents or alcoholic beverages. The sensors were operated in dynamic operation using temperature cycled operation (TCO), which is a well-known method for increasing sensitivity and selectivity of gas sensor systems based on MOS sensors (Heilig et al, 1997;Lee and Ready, 1999;Paczkowski et al, 2013;Baur et al, 2014). The resulting signals, after pre-processing and feature extraction, were analyzed by linear discriminant analysis (LDA), a multivariate pattern recognition method which separates different classes of input data while trying to group data sets of the same assigned group (Klecka, 1980;Gutierrez-Osuna, 2002).…”

Abstract. Pulsed laser deposition (PLD) at room temperature with a nanosecond laser was used to prepare WO 3 layers on both MEMS microheater platforms and Si/SiO 2 substrates. Structural characterization showed that the layers are formed of nanoparticles and nanoparticle agglomerates. Two types of layers were prepared, one at an oxygen partial pressure of 0.08 mbar and one at 0.2 mbar. The layer structure and the related gas sensing properties were shown to be highly dependent on this deposition parameter. At an oxygen pressure of 0.2 mbar, formation of ε-phase WO 3 was found, which is possibly contributing to the observed increase in sensitivity of the sensor material.The gas sensing performance of the two sensor layers prepared via PLD was tested for detection of volatile organic compounds (benzene, formaldehyde and naphthalene) at ppb level concentrations, with various ethanol backgrounds (0.5 and 2 ppm) and gas humidities (30, 50 and 70 % RH). The gas sensors were operated in temperature cycled operation. For signal processing, linear discriminant analysis was performed using features extracted from the conductance signals during temperature variations as input data.Both WO 3 sensor layers showed high sensitivity and selectivity to naphthalene compared to the other target gases. Of the two layers, the one prepared at higher oxygen partial pressure showed higher sensitivity and stability resulting in better discrimination of the gases and of different naphthalene concentrations. Naphthalene at concentrations down to 1 ppb could be detected with high reliability, even in an ethanol background of up to 2 ppm. The sensors show only low response to ethanol, which can be compensated reliably during the signal processing. Quantification of ppb level naphthalene concentrations was also possible with a high success rate of more than 99 % as shown by leave-one-out cross validation.
