Green and Rapid Determination of Phthalates in Mineral Water From Virgin and Recycled PET Bottles

Journal of Mass Spectrometry, Volume 61, Issue 8, August 2026.
ABSTRACT This study investigates the presence and quantification of phthalates released into mineral waters from virgin and recycled polyethylene terephthalate (PET) bottles. A green, solvent‐free analytical method based on solid‐phase microextraction (SPME) coupled with gas chromatography–mass spectrometry (GC/MS) was developed and validated to detect

Evaluating Stabilizers Effects on Aroma Release Dynamics in Ice Cream: A PTR‐ToF‐MS Analysis

Journal of Mass Spectrometry, Volume 61, Issue 8, August 2026.
ABSTRACT Capturing the dynamic volatilome of frozen matrices during phase transitions remains an analytical challenge, typically requiring invasive sampling. This study employs proton transfer reaction time‐of‐flight mass spectrometry (PTR‐ToF‐MS) as a rapid, noninvasive technique that directly samples headspace volatiles without preconcentration to ...

Effect of carcass storage condition on searcher efficiency trials for conservation detection dogs

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
We investigated the influence of storage condition on bat carcass odor through chemical analysis. Additionally, we tested the detectability of 3 carcass storage conditions through searcher efficiency trials with conservation detection dogs. Only 20% of the chemicals observed were shared across all 4 carcass storage conditions.

Bacterial Volatile Organic Compounds Mediate a Cooperative Relationship Between Bacteria and Plants Under Heavy Metal Stress

Microbial Biotechnology, Volume 19, Issue 8, August 2026.
In this brief report, we propose a scenario in which bacterial volatile organic compound (BVOC)‐mediated communication with plants can be interpreted as a form of plant–microbe cooperation under heavy metal stress. Different VOCs are emitted depending on bacterial stress states, and VOCs from heavy metal‐stressed bacteria modulate plant defense ...

Aboveground and Belowground Insect Herbivory Changes Maize‐Wireworm Interactions via Root Volatile Cues

Plant, Cell &Environment, Volume 49, Issue 8, Page 5689-5702, August 2026.
ABSTRACT The rhizosphere harbours critical plant‐herbivore interactions often mediated by small lipophilic molecules (SLMs). Despite the agricultural importance of many soil‐dwelling insects, surprisingly little is known about chemically mediated belowground crop‐pest interactions. Root and shoot herbivores can influence these interactions by modifying

Green and sustainable evaluation of methods for sample treatment in drug analysis

Green Analytical Chemistry
The time-consuming nature of many sample treatment protocols continues to be recognized as the main bottleneck of analytical procedures, which, in most cases, use long analysis times, excessive amounts of solvents and reagents, and energy.

Attraction of nocturnal scarab beetles by unusual floral volatiles in a Banksia (Proteaceae) with functionally diverse pollinators

Plant Biology, Volume 28, Issue 5, Page 1454-1466, August 2026.
Banksia attenuata (Proteaceae) attracts nocturnal scarab beetles with an unusual floral scent—the beetles pollinate the flower as they feed on pollen and nectar and mate on the inflorescences. Abstract Pollination by beetles has evolved multiple times in flowering plants but with relatively few plant species adapted specifically to pollination by ...

Sustainable Ball Milling‐Assisted Synthesis of Bread Waste‐Derived Highly Porous Carbons for Adsorption‐Based Applications

ChemPhysChem, Volume 27, Issue 13, 14 July 2026.
A simple strategy is proposed to convert food waste such as dry bread into highly porous carbons that can be used for catalysis and adsorption‐related applications. Namely, a fast ball milling of dry bread and a mild activation agent, followed by carbonization at 800°C, is used to obtain porous carbons with surface areas up to 2400 m2/g.
