Layered double hydroxides (LDHs) and LDHs-derived materials are emerging as potential engineered adsorbents for the protection of water environment. Particularly, LDHs intercalated with different guest compounds (GC-LDHs), which differ from traditional interlayer anions (such as Cl−, SO42−, NO3−, CO32−, and PO43−), are widely reported by recent studies showing their promising multifunctional roles in water purification. Herein, this review systematically presents the synthesis methods and characterization techniques of GC-LDHs and their application as adsorbents in removing potentially toxic elements (PTEs) from the aqueous phase. This review also elaborates on the important roles of complexation, chelation, precipitation, isomorphic substitution, and ion exchange in the process of PTE removal by GC-LDHs. Among them, compared with PTE cations, ion exchange is an additional mechanism for the removal of PTE oxyanions by GC-LDHs. Furthermore, the influence of pH, ionic strength, temperature, physiochemical properties of original LDHs and guest compounds on the GC-LDHs adsorption performance are also summarized. Finally, the development trends and future challenges related to GC-LDHs are proposed. © 2022 Taylor & Francis Group, LLC.

Excessive fluoride emissions threaten ecological stability and human health. Previous studies have noted that industrial sources could be significant. However, quantifying industrial fluoride emissions has not been yet reported. In this study, both bottom-up and top-down approaches were used to estimate the fluoride emissions in the Nansi Lake Basin. Global and local spatial autocorrelation were adopted to reveal the spatial agglomeration effects. The fluoride emissions calculated by the bottom-up approach were larger than those calculated by the top-down method. The highest fluoride input mainly occurred in Zoucheng and Mudan. The highest fluoride emissions mainly occurred in Zoucheng and Rencheng using the bottom-up approach. The highest fluoride emissions mainly occurred in Zoucheng and Yanzhou using the top-down approach. Mining and washing of bituminous coal and anthracite (BAW) was the most significant source of fluoride input and emissions. A significant spatial agglomeration effect of fluoride emissions was found. These findings could provide a method for accurate industrial fluoride emission estimation, complement the critical data on the fluoride emissions of main industrial sectors, and provide a scientific basis for tracing fluoride sources. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

The widespread occurrence of emerging brominated flame retardant tetrabromobisphenol S (TBBPS) has become a major environmental concern. In this study, a nanoscale zero-valent iron (nZVI) impregnated organic montmorillonite composite (nZVI-OMT) was successfully prepared and utilized to degrade TBBPS in aqueous solution. The results show that the nZVI-OMT composite was very stable and reusable as the nZVI was well dispersed on the organic montmorillonite. Organic montmorillonite clay layers provide a strong support, facilitate well dispersion of the nZVI chains, and accelerate the overall TBBPS transformation with a degradation rate constant 5.5 times higher than that of the original nZVI. Four major intermediates, including tribromobisphenol S (tri-BBPS), dibromobisphenol S (di-BBPS), bromobisphenol S (BBPS), and bisphenol S (BPS), were detected by high-resolution mass spectrometry (HRMS), indicating sequential reductive debromination of TBBPS mediated by nZVI-OMT. The effective elimination of acute ecotoxicity predicted by toxicity analysis also suggests that the debromination process is a safe and viable option for the treatment of TBBPS. Our results have shown for the first time that TBBPS can be rapidly degraded by an nZVI-OMT composite, expanding the potential use of clay-supported nZVI composites as an environmentally friendly material for wastewater treatment and groundwater remediation. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

＜正＞*** Illicit drugs, which non-medical use is forbidden by the laws, have been abused widely around the world and cannot be completely metabolized by the human and wastewater treatment（1）. Therefore, it is crucial to estimate the aquatic toxicity and fate of illicit drugs. Previous studies have been performed in all over the world to detected levels of illicit drugs in surface waters（2）.

Permafrost degradation substantially affects water resources within the cryosphere. It is crucial to elucidate the dynamics of water availability influenced by both permafrost degradation and climate change to fully comprehend the water cycle in cold regions, such as the Qinghai‒Tibet Plateau (QTP). While existing studies have established the hydrological consequences of permafrost degradation through altered soil hydraulics and water storage capacity, the complex interplay between thawing permafrost and vegetation dynamics—particularly their synergistic regulation of precipitation partitioning and runoff generation through root-zone water accessibility—are poorly understood, creating critical knowledge gaps in predicting long-term water availability trajectories. In this study, we explore the influence of permafrost-vegetation interactions on regional water availability on the QTP by integrating the effects of permafrost degradation on vegetation into the Budyko-Fu model. Our results reveal a consistent increase in surface runoff ( R ) of the permafrost regions from 1981 to 2100, predominantly driven by rising precipitation. However, shifts in vegetation patterns, prompted by permafrost degradation, significantly modify hydrological partitioning, leading to non-monotonic variations in the runoff to precipitation ratio ( R/P ). Notably, early-stage permafrost thaw enhances vegetation growth and evapotranspiration, which results in a decrease in R/P . Conversely, deeper permafrost thaw ( e.g ., beyond the root zone of vegetation) can lead to vegetation degradation, which subsequently reduces evapotranspiration and consequently increasing the R/P ratio. These findings underscore the pivotal role of vegetation in regulating the hydrological cycle and affecting water availability in permafrost-affected regions.
