Recent Advances in the Extraction of Polycyclic Aromatic Hydrocarbons from Environmental Samples

open access: yesMolecules, 2020
Polycyclic aromatic hydrocarbons (PAHs) comprise a group of chemical compounds consisting of two or more fused benzene rings. PAHs exhibit hydrophobicity and low water solubility, while some of their members are toxic substances resistant to degradation.

Gas Chromatography‐Based Methods for Profiling Volatile Off‐Aroma Compounds in Grain Legumes: A Review

open access: yesLegume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Instrumental characterisation of the volatile organic compounds (VOCs), responsible for off‐aroma, is mainly centred on gas chromatography‐based techniques. Despite previous reviews that have addressed the chemical compounds and biosynthetic pathways of off‐aroma generation, to date, there is a lack of a comprehensive review that critically ...

Nitrogen isotope analysis of ammonium and glycine [PDF]

open access: yes, 2005
Stable isotope techniques can be used as a tool in nitrogen cycling studies of different ecosystems. The studies are based on measurement of the heavy (15N)- to- light (14N) isotopic ratios of nitrogen in different biospheric pools.

Host tree preference and performance of the Eurasian spruce bark beetle (Ips typographus) on Scots pine

open access: yesPest Management Science, Volume 82, Issue 6, Page 5850-5860, June 2026.
Ips typographus showed lower reproductive output in an occasional host (Pinus sylvestris) under laboratory conditions, and did not prefer its main host (Picea abies) over P. sylvestris in two‐choice bioassays. Abstract BACKGROUND The Eurasian spruce bark beetle, Ips typographus, is one of the most serious pests of Norway spruce (NS, Picea abies), with ...

Integrated Assessment of Lipid Oxidation and Off‐Flavor Formation in Plant Protein Powders

open access: yesJournal of the American Oil Chemists' Society, Volume 103, Issue 5, Page 371-386, May 2026.
Impact of residual lipids on oxylipin and off‐flavor formation in commercial plant proteins: A detailed analysis of precursor‐product relationships by GC‐FID, LC‐MS/MS, and GC‐MS. ABSTRACT The widespread adoption of plant proteins is hindered by their inherent off‐flavors, often linked to lipid oxidation products.

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 5, Page 2206-2224, May 2026.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...

Volatile organic compounds emitted from fungal-rotting beech (Fagus sylvatica) [PDF]

open access: yes, 2008
Chemo-communication is an important mode of interaction within ecosystem. The living organism in the ecosystem can deliver signals to conspecifics, to co-organisms, and unintentionally to their enemies, by emitting the volatile organic compounds (VOCs ...

GC × GC‐TOF MS and Sensory Profiling of Aroma Compounds in Magnolia Species: Effects of Processing Methods on Volatile Retention in M. wufengensis

open access: yesFlavour and Fragrance Journal, Volume 41, Issue 3, Page 487-503, May 2026.
The first comparative analysis of Magnolia scents reveals that M. wufengensis is characterised by a high aldehyde content, exhibiting a fresh, sweet, and fruity fragrance profile. Furthermore, freeze‐drying preserves 6.7 times more 2‐nonenal compared to shade‐drying, highlighting its superior efficacy in retaining key volatile compounds.
