Scenario-specific numerical simulations were performed in order to assess the diffusive spreading of volatile fuel constituents and their biodegradation in the unsaturated soil zone. This is especially important in arid regions where the groundwater table... see more

Paper description:The headspace method (HS) enables us to study the composition of volatile compounds by using only 0.1 g of plant material and without creating artefacts during isolation.Volatiles stored in twigs are separated from needle volatiles and t... see more

In Asia, the pine sawyer beetle Monochamus alternatus Hope (Coleoptera: Cerambycidae) is the most important vector of the pinewood nematode Bursaphelenchus xylophilus Steiner and Buhrer (Aphelenchida: Parasitaphelenchidae), the causal agent of pine wilt d... see more

Samples of ambient air were simultaneously collected at three different sites of Mexico City in March of 1997 in order to quantify the most abundant volatile aromatic compounds and estimate the source contributions by applicati... see more

A study has been conducted to investigate changes of volatile components during soy sauce fermentation. During the fermentation, many volatile components produced may contribute to soy sauce flavor. THe volatile identified by GC-MS werw classified into hy... see more

The aim of this work was to evaluate the volatile fraction profile of acacia raw honey from different countries: Romanian, Spain, and Czech Republic. A melissopalynological analysis was conducted on all the batches in order to verify them as belonging to ... see more

Solid-phase microextraction in combination with gas chromatography and mass-spectrometry (GC-MS) was used for determination of benzene, toluene, ethylbenzene and o-xylene (BTEX), polycyclic aromatic hydrocarbons (PAH), and for identification of volatile o... see more

Protium aracouchini (Aubl.) Marchand [sin Icica aracouchini Aubl.], which occurs in the Adolpho Ducke Forest Reserve, in the Brazilian Amazon, was evaluated for the presence of galls, for resin exudation and the composition of the essential oils from the ... see more

Diesel oil contamination is a growing environmental concern in most crude oil processing regions of the world. This study assessed the efficacy of both fresh and powdered Eichhornia crassipes (water hyacinth) as potential biostimulants in the remediation ... see more
