Summary: Mercury is a typical toxic heavy metal that brings immeasurable hazards to the environment and humans, but the molecular mechanisms of its toxicity are not yet clear. This study provides visual evidence that exposure to mercury ions (Hg2+) can induce a secondary stress response in biological systems, leading to hypoxia microenvironment. The researchers successfully developed two NTR-selective fluorescent probes to evaluate the degree of hypoxia in vivo and in vitro, and observed an increase in NTR levels in response to mercury exposure, similar to the changes seen in extrinsic hypoxia exposure.

Summary: Sulfamethoxazole (SMX), a commonly found antibiotic in the environment, is efficiently degraded by a mixed bacteria community including Aeromonas caviae strain GLB-10. In addition to the bioproducts generated by single bacteria, the mixed bacteria produce acetanilide and hydroquinone during SMX degradation. The degradation mechanism of the mixed bacteria is more complex and involves acetylation, sulfur reduction 4S pathway, and ipso-hydrolysis. The molecular mechanism reveals the overexpression of outer membrane proteins and catalase peroxidase, as well as the involvement of 6-hydroxynicotinate 3-monooxygenase.

Summary: In order to monitor the pollution level of benzotriazole ultraviolet stabilizers (BUVSs), nitrogen-doped metal-organic framework derived porous carbon (UiO-66-NH2/DC) was integrated into a polyvinylidene fluoride mixed matrix membrane (PVDF MMM) as an adsorbent. The UiO-66-NH2/DC showed excellent extraction performance for BUVSs, solving the problem of difficult enrichment of large-size and hydrophobic targets. An influential method based on dispersive membrane extraction coupled with ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) was developed for the simultaneous analysis of four BUVSs in environmental water samples. This study expands the application prospects of porous carbon derived from MOF for sample pretreatment of pollutants in water.

A Zr(IV)-based metal-organic framework functionalized with amino groups (NH2-UiO-66) was used as a supporting platform to anchor gold nanoparticles (AuNPs), preventing the migration and aggregation of AuNPs. The addition of Hg2+ enhanced the peroxidase-like activity of the composite (AuNPs/NH2-UiO-66), accelerating the oxidation reaction. The color change in the reaction solution allowed for the quantitative detection of Hg2+.

Summary: This study investigates the effects of soil aging on the toxicity of microplastics to soil fauna. The results show that soil aging slightly alters the surface properties and morphology of microplastics, and significantly affects the release of additives. Additionally, a less diverse microbial community is formed on the surface of microplastics compared to the surrounding soils. Aged microplastics have a significant impact on the reproduction of soil worms, particularly those aged in soil with manure, and disrupt their gut microbiota. Changes in biofilm features and leaching properties of microplastics during aging are the main contributing factors to these shifts. This study provides preliminary insights into the role of soil aging in the toxicity of microplastics to soil fauna.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
