Summary: This study aimed to assess the impact of two agrotechnical factors (floor management and nitrogen dose) on the yield and primary and secondary metabolites in 'Sampion' apple fruit. Living mulch did not decrease yield compared to herbicide fallow. Apples were found to contain a rich composition of phenolic and volatile organic compounds, which varied with the evaluated factors and weather conditions. Precipitation deficit and high summer temperatures hindered fruit growth and development, resulting in a higher content of phenolic compounds in the fruit flesh from trees in herbicide fallow. Living mulch, acting as a regulator of nitrogen availability to trees, stimulated anthocyanin synthesis, which was enhanced by low average temperatures at harvest time, leading to extensive fruit skin red blush.

Summary: Gas molecules and volatile compounds in the air have an impact on product purity and health. Luminescence metal-organic frameworks (LMOFs) have been widely reported as sensor materials for detecting different compounds. This review explores the luminescence mechanisms of LMOFs and the interactions between host and guest molecules, and describes the state-of-the-art LMOF-based sensors for various gas molecules and volatile organic compounds (VOCs). It can contribute to the further development and practical application of LMOFs in sensor combinations.

Summary: Competition for adsorption sites between atmospheric moisture and volatile organic compounds can significantly impact the VOC removal performance of metal-organic framework adsorbents like MIL-101. In this study, a vapor phase deposition of polydimethylsiloxane (PDMS) was used to create more hydrophobic MIL-101 composites, resulting in enhanced internal hydrophobicity and intact porosity. The MIL-101-PDMS composite showed superior performance in capturing toluene, exhibiting higher adsorption capacity and overall capture rate compared to pristine MIL-101, and maintaining excellent structural stability and adsorption performance after multiple sorption/desorption cycles.

Summary: Biochar derived from corn stalk doping with activated carbon was used to sorb benzene and o-xylene. The specific surface area, total pore volume, and micropore volume of microwave biochar increased with increasing microwave power, which resulted in higher adsorption capacities for benzene and o-xylene. Benzene adsorption was mainly influenced by surface interaction and partition mechanisms, while o-xylene adsorption was governed by pore filling.

Summary: Tree stems are important sources of volatile organic compounds (VOCs) that play crucial roles in tree defense and atmospheric chemistry. However, the magnitude and environmental drivers of stem VOC emissions in various forest ecosystems are not well understood. Drought can lead to nonlinear decreases in monoterpene and acetaldehyde emissions, but large peaks of emissions can still occur in late summer under dry conditions, possibly due to abiotic or biotic stressors.

Summary: This study investigates the impact of volatile organic compounds (VOCs) on ozone formation by considering their photochemical loss. The results show that neglecting the chemical loss of VOCs leads to underestimation of the contributions from highly reactive VOC components and overestimation of contributions from VOC components with lower chemical activity. Additionally, the estimation of ozone formation may be underestimated if the atmospheric photochemical loss is not taken into account.

Summary: This study identified the concentrations of volatile organic compounds (VOCs) in the Huangshui River of the Tibetan Plateau. The results showed that sediment had significantly higher concentrations of alkenes, alkanes, and aromatics compared to water. VOC concentrations in summer were higher than in spring and winter. Some VOCs exceeded national standards and were related to human activities. Total organic carbon (TOC) was a major factor influencing the presence of VOCs in the river.

Summary: The concentrations of BTEX pollutants were investigated in an oil Refinery in Iran during summer and winter seasons. Air samples were collected from the breathing zones of supervisors, safetymen, repairmen, site men, and all workers. Carcinogenic and non-carcinogenic risk values were calculated using Monte Carlo simulations. BTEX concentrations were higher in summer, especially toluene and ethylbenzene. The exposure to benzene exceeded the threshold limit value for repairmen and site men in both seasons. Non-carcinogenic risk values for several compounds exceeded the acceptable level of 1.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
