Adsorption technology is an essential part of modern water treatment. However, only a handful of adsorbent materials are used industrially, which is in striking contrast with the exponentially increasing scientific publishing activity. In this perspective, the aim is to discuss the global progress on the adsorbent materials development by using the reported adsorption capacities as a simple probe. An automated text analyzer employing a large language model was used to extract adsorption data.

Co-generation of fresh water and electricity from solar energy offers a sustainable pathway to global water and energy challenges. Here, we report a high-performance solar-driven water-electricity co-generator integrating a front-side coupling (FSC) strategy, where a precisely engineered thin water film on the front surface of photovoltaic cells enables synergistic optical-thermal regulation.

The lifestyles and worldviews of indigenous communities have long been deeply intertwined with natural resources, particularly water. These vital resources are now severely threatened by systemic social marginalization and the enduring impacts of colonization, further violating the human right to water access. Our primary objective was to assess the domains and correlates of water insecurity in a Pilagá community in Formosa, Argentina.

Microplastic contamination in fish presents a growing environmental and public health concern, with implications that extend from aquatic ecosystems to consumer safety. This review presents a systematic summary of current knowledge about the health hazards of microplastics in fishes, including bioaccumulation, transfer mechanisms in the food chain, and the roles of microplastics as carriers of antibiotic-resistant genes.

The contamination of marine environments by chemical pollutants poses a significant threat to both ecosystem health and human food safety, affecting marine One Health by disrupting the interconnected well-being of organisms, ecosystems, and humans. A diverse array of contaminants including metals, persistent organic pollutants, pharmaceuticals, personal care products, per- and polyfluoroalkyl substances (PFAS), pesticides, among others, can accumulate in fish and seafood, raising concerns over dietary exposure.

The global challenge of water security is intensifying, driven by rapid population growth, industrialisation and climate change, making sustainable water reclamation and reuse an essential strategy for resilience. This study explores the potential of innovative Mobile Constructed Wetlands (MCW) as a decentralised, nature-based solution to enhance water security through the integration of water safety, accessibility and affordability assessments.

Denitrification using Pd-based catalysts converts N-oxyanions into harmless products. However, the metal cost and scarcity are barriers to application. In this work, we synthesize water-suspended, structure-controlled Ni-core/Pd-shell nanoparticles (Ni@Pd NPs) that show Pd-catalyzed nitrite (NO2⁻) reduction catalysis promoted by Ni.

The growing global demand for freshwater has intensified research into energy-efficient desalination technologies. Among various desalination methods, distillation-based technologies can utilize renewable solar sources and low-grade waste heat but are typically energy intensive. In recent years, solar thermal interfacial evaporation has emerged as a promising approach to enhance energy efficiency in seawater distillation by delivering heat directly to the liquid-vapor interface and bypassing the bulk fluid.

The combination of climate change, growing population, and development of urbanization has exacerbated the existing water resources crisis. There is no natural resource that is more precious than water, and all aspects of human livelihoods have their foundation connected to water resources. However, many regions of the globe are experiencing critical conditions linked to extreme hydrological events, particularly floods and droughts. This study aims at exploring socio environmental benefits of floodwater utilization in a changing climate world.

Wicked problems, such as water security, require a shift to transdisciplinary research by bringing disciplinary perspectives, conducting participatory research, and developing case-specific solutions.
