In this study, a novel 2D/2D/2D ternary heterostructure comprising Ti₃C₂ MXene (TC), Bi₂MoO₆ (BMO), and g-C₃N₄ (CN) was rationally engineered to achieve superior solar-driven photodegradation of waterborne pharmaceutical contaminants. The optimized TC/BMO-15/CN hybrid exhibited outstanding degradation efficiencies of ∼100% for cefixime in 90 min and 99% for naproxen in just 30 min, significantly outperforming pristine CN, BMO, and the binary BMO-15/CN photocatalyst. Comprehensive structural, optical, and electrochemical characterizations revealed that the synergistic integration of TC as a conductive bridge-combined with the optimal BMO content and intimate interfacial coupling-enhanced light harvesting, facilitated efficient tri-component interfacial charge transfer, and prolonged charge carrier lifetimes. Mechanistic investigations using reactive species quenching, ESR spectroscopy, and in situ light-irradiated XPS confirmed the formation of an S-scheme heterojunction, which enables selective spatial retention of high-energy charge carriers for redox reactions. By uniting architectural synergy with S-scheme charge transfer, the system enhances charge dynamics and enables efficient mineralization of complex pharmaceutical pollutants. Furthermore, the TC/BMO-15/CN catalyst demonstrated excellent structural stability and maintained high degradation performance across various water matrices and multiple reusability cycles.

CDs have good water solubility, stability and fluorescence properties, and thus are widely used in the fields of bioimaging, sensors and photocatalysis. While CDs face interference from other metal ions when used as sensors for detecting iron ions, this study demonstrates that the prepared biomass carbon dots (BCDs) exhibit selective detection of Cr(Ⅵ). In this study, nitrogen-doped biomass carbon dots (N-BCDs) were successfully prepared by microwave-assisted method using hawthorn branch as the carbon source and urea as the nitrogen source, and their morphological structures and optical properties were characterised. The results showed that the synthesised N-BCDs had an average size of 3.3 nm and exhibited bright blue fluorescence under UV illumination. The excitation wavelength is located at 307 nm, and the optimal emission wavelength is 372 nm, with a quantum yield of 16.08% and good fluorescence stability. The mixture of N-BCDs with Cr(Ⅵ) causes obvious fluorescence quenching, which was used as fluorescence probe for Cr(Ⅵ). The method had good linear correlation in the range of 20-100 μM for Cr(Ⅵ), and the limit of detection is as low as 0.84 μM. The fluorescence quenching of N-BCDs by Cr(Ⅵ) is a combination of dynamic quenching and internal filtration effects.

While the placenta is a known target of PFAS toxicity, most in vitro studies use two-dimensional (2D) cell culture models, often focusing on late-pregnancy tissue or blood PFAS concentrations and examining single compound exposures. In this study, we measure placenta PFAS concentrations in early pregnancy and design a placenta-relevant PFAS mixture to assess its impact on trophoblast function using a three-dimensional (3D) trophoblast spheroid model. PFAS levels in first-trimester placental tissue were quantified using liquid chromatography/triple quadrupole mass spectrometry. Six PFAS: perfluorononanoic acid (PFNA), perfluorooctanesulfonic acid (PFOS), perfluorobutanoic acid (PFBA), perfluorooctanoic acid (PFOA), perfluorohexanesulfonic acid (PFHxS), and perfluorodecanoic acid (PFDA); were selected based on their placenta concentrations and relevance to pregnancy complications to design the placenta real-life PFAS mixture. Next, trophoblast spheroids were propagated from two different cell lines, JEG-3 and HTR-8/SVneo, to assess the effects of PFAS mixture on trophoblast viability, apoptosis, invasion, hormone production, and gene expression. While trophoblast spheroid viability remained largely unaffected, we observed changes in trophoblast function. PFAS exposure significantly increased invasiveness in JEG-3 spheroids at 48 hours, but markedly reduced it in HTR-8/SVneo spheroids at 96 hours across varying concentrations. Additionally, pregnancy-specific hormone e.g. β-hCG production declined after 48 hours of PFAS mixture exposure in JEG-3 spheroids. Gene expression analysis revealed altered apoptosis and proliferation pathways in both trophoblast spheroids.

Climate warming altered biochemical cycling and further threatened ecosystem imbalance, affecting methane (CH₄) emissions budget. To reveal the complex interplay of soil properties and microbial communities governing CH₄ emissions responding to temperature changes in alkaline wetland, 60-day incubation experiments with temperature gradients (5°C, 18°C, 25°C, 35°C) were conducted using soil collected from Zhalong wetland in northern China. The results showed that CH₄ emission increased along with elevated temperature and peaked at 35°C with 169.10±65.42 mg C kg^-1 dry soil, 343.7-fold higher than that at 5°C. Increased NH₄⁺-N and dissolved organic carbon concentrations induced by elevated temperatures significantly regulated CH₄ emission (p<0.05). Hydrogenotrophic methanogens (Methanobacterium) exhibited greater sensitivity to temperature fluctuations than acetoclastic methanogens (Methanosarcina, Methanosaeta), and dominated in archaeal communities with proportion of 21.8% under low and moderate temperature. Moreover, the accelerated Fe reduction process stimulated enrichment of methanogen (Methanobacterium, 8.8%→9.3%) while suppressing methanotrophs (Candidatus _Methanoperedens, 5.0%→4.2%), thereby contributing to higher CH₄ emissions under rising temperature. Besides, upregulated methanogenic genes (mcrA, fwdA, cdhC, mtrH) contributed to increased CH₄ production at 35°C.

In this context, understanding the extent of geographic and social disparities in the distribution of changes in walkability is also warranted. This study presents a nationwide assessment of how physical environment characteristics known to impact health and welfare are changing over time in the U.S. We integrate longitudinal data for over 164,000 participants in the American Cancer Society's prospective Cancer Prevention Study (CPS-3) cohort with objectively assessed built environment data at two time points (2013 and 2020). Descriptive and longitudinal change detection modeling of a geographically and ethnically diverse national sample of over 109,000 non-movers revealed some improvements in urban compactness, street connectivity, transit accessibility, urban diversity, and overall walkability levels. Changes in walkability across U.S. regions and the urban-rural continuum exhibited geographic disparities. Participants in rural areas and small towns experienced a modest reduction in walkability, whereas the reverse was observed for those in urban areas. Walkability increased over time for all age and racial groups but exhibited considerable variations. The increase in walkability over time was greatest for Hispanics and Blacks compared to non-Hispanic Whites.

Since the concept emerged in 2005, new data, methods, and tools have been generated by the scientific community to assess the different components of the exposome and their impacts on human health. Currently, one of the main challenges is accounting for the diversity and complexity of exposures and their effects on health in risk assessment, which might be accomplished by integrating the exposome into this process. To this end, a working group was constituted by Anses to develop a strategy to integrate the exposome concept in risk assessment and more generally in the work produced by health safety agencies. We present the principal challenges to be addressed by considering 8 themes covering relevant aspects of the exposome and we made recommendations for each theme: 1) characterization of the exposome in epidemiological surveys; 2) exposome data; 3) risk assessment of chemical mixtures; 4) aggregation of multiple sources and routes of exposure; 5) dynamics of the exposure in the context of time, space, and social factors; 6) establishment of reference values; 7) multiple factors in risk, benefit and health impact assessment; and 8) eco-exposome. Then, we propose practical recommendations with short-, medium-, and long-term time scales to progressively operationalize the exposome into risk assessments implemented by health safety agencies.

Analysis revealed that DMF modification markedly boosted defect density (I_D/I_G = 1.0732), specific surface area (397 m²/g, marking a 2.17 times rise compared to the control group), and the C=O bond content on the surface (23.90%), cumulatively leading to a 38.4% surge in the rate of BPA degradation relative to the original system. This study first identifies a threshold dependence between the dosage of DMF and the formation of pores, enabling accurate regulation of catalytic efficiency via dosage optimization. The reaction was driven by the synergistic activation of PMS by defect sites and C=O groups, resulting in efficient degradation via a non-radical pathway (dominated by ¹O₂/O₂^•-).
