Summary: This study investigated the structural characteristics and main properties of dissolved organic matter (DOM) in farmland soils near Urumqi, China, using three-dimensional fluorescence spectroscopy (EEM) and UV-visible spectrum technology, and analyzed its possible sources and pathways through spectroscopic indices. The results showed that humic-like substances were the main composition of soil DOM, and its autogenesis characteristics were not obvious. The DOM properties in the southern region of Urumqi were higher than those in the northern region and in Fukang, China, and higher in the upper layers of the soil than in the deeper layer. Spectroscopic analysis indicated that the DOM in these regions mainly originated from microbial metabolites. These findings provide important scientific data for further research on pollutant behavior and pollution control in the region.

Summary: This study investigated the effects of Cd and HA on ARGs, MGEs, and bacterial communities in soil. The results showed that the addition of Cd increased the abundance of ARGs and MGEs, while high concentrations of HA suppressed their expression. Available Cd was found to be the dominant factor influencing ARGs, and Proteobacteria were identified as the main host bacteria. Therefore, adding high concentrations of humic acid to Cd-contaminated soil can reduce the enrichment of ARGs.

Summary: Developing an adsorbent with a fast adsorption rate is important for ensuring high adsorption capacity and selectivity of gold ions. In this study, two humic acid modified phenolic resin (SHAR and NSHAR) were prepared using a simple two-step method with water as solvent. These adsorbents can efficiently recover Au(III) from mixed metal solutions. The adsorption behavior and mechanism of Au(III) on SHAR and NSHAR were investigated, and it was found that the process belongs to multi-molecular chemical adsorption. The adsorption of Au(III) on SHAR and NSHAR is endothermic and spontaneous. Unlike conventional adsorbents, Au(III) is reduced to zero valent gold and deposited on the adsorbent. NSHAR achieves adsorption equilibrium in just 10 minutes with a high adsorption capacity of 927 mg center dot g(-1) (compared to SHAR, which takes 50 minutes and has a capacity of 1440 mg center dot g(-1)). This research provides a new approach for the quick and efficient recovery of gold.

Summary: The study investigated the effect of compost application on the soil Cd concentration in cacao farms and found that compost application can reduce the soluble Cd content in the soil. Additionally, it was found that compost application increases the Cd bound to humic acids in the soil, thereby reducing its availability to plants. Furthermore, the quality of the compost applied also plays a role in mitigating Cd contamination.

Summary: Pesticide exposure affects insect immune response and may lead to honeybee colony deaths. Imidacloprid and amitraz alter the oxidative response of insect hemocytes at different concentrations of the immune stimulator, zymosan A. Different insect orders have different responses to pesticide exposure and their immune systems may render honeybee colonies more susceptible to infection and pests.

Summary: The efficiency of bioretention systems in mitigating stormwater depends largely on their ability to quickly infiltrate runoff. This literature review focuses on clarifying the influence of vegetation on the hydraulic conductivity of bioretention media, aiming to provide better guidance on plant selection for system durability. Overall, studies show a positive impact of plants on water infiltration and percolation in both greenhouse and field conditions. The selection of vegetation plays a crucial role in maintaining initial media infiltration rates, with different types of plants showing varying levels of improvement.

Summary: The rapid fabrication of high-performance composite membranes based on CMPs using simple and low-cost methods is challenging. In this study, three CMPs-based composite membranes were rapidly fabricated with adjustable size using unidirectional diffusion synthesis. The microstructural design enhanced the rejection rates of the membranes and they showed strong hydrolytic resistance, thermal stability, and acid-base resistance. Electrostatic adsorption and the adjustable microstructures significantly varied the repellence of the membranes to different charged molecules.

Summary: Introducing defects into porous metal-organic frameworks is important for improving their adsorption performance. Quasi-MOFs, an underutilized variant of large-scale, fundamentally deficient MOFs, have been found to have substantial amounts of unsaturated metal sites to offset the drawbacks of MOFs. In this study, a quasi-MOF was produced using a water-stable MOF and demonstrated significantly improved phosphate adsorption capability due to the presence of defect sites.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, a nanofibrous layered structure of Ff-Ti3C2Tx-Co3O4 was prepared by self-assembling nanofibrous Co3O4 with lamellar fluorine-free MXene (Ff-Ti3C2Tx). The Ff-Ti3C2Tx-Co3O4 exhibited excellent catalytic activity for degradation, resistant to ionic interference, and maintained high removal efficiency of sulfamethoxazole (SMX) in municipal wastewater. The rapid SMX degradation involved fast electron transfer in redox cycles with PMS and the generation of 1O2 via PMS ->center dot O2 -> 1O2. This work provides new insights into antibiotic degradation mechanisms and electron transfer based on PMS activation.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
