Plant-parasitic nematodes (PPNs) are one of the most destructive plant pathogens worldwide, and controlling them is extremely challenging. Volatile organic compounds (VOCs), which naturally exist in plants and microorganisms, play an important role in the biological control of PPNs and are considered potential substances for the development of commercial nematicides. This paper summarizes the VOCs produced by microorganisms and plants as well as their toxic effects on PPNs. VOCs from 26 microbial strains and 51 plants that are active against nematodes from over the last decade were reviewed. Furthermore, the mechanisms of toxicity of some VOCs against PPNs are also illustrated.

The olfactory system of insects plays a vital role in their survival by enabling them to detect chemical cues and adapt to changing environments. The rape stem weevil, Ceutorhynchus asper, is a significant pest posing a challenge for rapeseed production due to its destructive feeding habit and increasing resistance to insecticides. So far, there's still limited knowledge about structure and function of odorant binding proteins (OBPs) in beetles like C.

Rapid and convenient enrichment and detection of volatile cinnamaldehyde (Cin) from a common herbal medicine, cinnamon, was achieved through a reliable MSPE-HPLC-DAD approach. The magnetic porous carbon material (Carbon-FeC/lignin) used for MSPE was prepared as follows. First, the metal organic framework (MIL-101-NH (Fe)) was synthesized using the solvothermal method.

Volatile organic compounds (VOCs) significantly impact air quality as photochemical smog precursors and health hazards. Catalytic oxidation is a leading VOC abatement method but suffers from catalyst deactivation due to metal sintering and competitive adsorption in complex mixtures. Strong metal-support interactions (SMSIs) provide atomic level control of interfacial electronic and geometric structures.

Ozone (O) is a primary pollutant affecting air quality in China, whose formation rate was non-linearly based on volatile organic compounds (VOCs) and nitrogen oxides (NOx). A comprehensive understanding of the key drivers governing O formation and its sensitivity to precursor variations presents a persistent research challenge, stemming from the complex interplay of underlying photochemistry, meteorology, and topography. To address this knowledge gap, we conducted synchronous measurements of O and its precursors at both an urban (JPU) and a mountain (LM) site in a typical city in eastern China, enabling concurrent evaluation of O formation sensitivity and diagnostic analysis of its underlying mechanisms.

Background: The link between exposure to environmental hazards and thyroid function has been relatively well established. However, evidence on environmental exposure to volatile organic compounds (VOCs) and thyroid function in the general population remains unclear.
Objectives: To assess the impact of individual and joint effects of VOCs exposure on thyroid function in a representative sample of U.
