Genomic surveillance of ESBL-producing Escherichia coli from community wastewater in São Tomé and Príncipe
The emergence and increasing spread of Escherichia coli producing extended-spectrum β-lactamase (ESBL) in water reservoirs poses a significant public health threat, particularly in low-resource settings. In this study 115 ESBL-producing E. coli (ESBL-Ec) were isolated from six community wastewater…

Hydro-environmental and ecological effects of drop structure in urban river system
Drop structures are common in urban rivers, yet their ecological effects on sedimentary bacterial communities insufficiently resolved. We investigated nine artificial units (single- and dual-drop configurations) along the urbanized Yangmei River, China. Using 16S rRNA sequencing, co-occurrence…

Impacts of wastewater treatment and the exposome on antibiotic resistance gene dynamics: Insights from Guadeloupe, a French Caribbean Island
Wastewater treatment plants (WWTPs) are global hotspots for disseminating antibiotic resistance genes (ARGs). Chemical compounds commonly found in wastewater, including antibiotics, biocides, non-steroidal anti-inflammatory drugs (NSAIDs), and heavy metals, along with climate variables and…

Chronic triphenyl phosphate exposure disrupts HPG axis and impairs reproduction in marine medaka (Oryzias melastigma)
Triphenyl phosphate (TPhP), a widely used organophosphorus flame retardant, has become a typical emerging pollutant in marine environments, yet its toxicity in marine fish is far from conclusive. This study investigated the chronic reproductive toxicity of TPhP in marine medaka (Oryzias melastigma)…

Harnessing ferric chloride dosing for removal of Maillard reaction-derived recalcitrant dissolved organic nitrogen during dewatering of municipal sludge treated by thermal hydrolysis-enhanced anaerobic digestion
Recalcitrant dissolved organic nitrogen (rDON) formed as a byproduct of thermal hydrolysis pretreatment (THP) resists mainstream biological nutrient removal and thus poses a challenge to water resource recovery facilities (WRRFs) that must achieve stringent total nitrogen standards. This study…

Drought-driven changes in emerging contaminant occurrence and distribution in groundwater: A Mediterranean catchment study
Droughts are projected to become more frequent and severe, threatening groundwater resources in Mediterranean regions by altering water quality and hydrological dynamics. This study provides for the first time a field-scale assessment of 85 emerging contaminants (ECs), including 41 pharmaceuticals…

Management of desalination brine and application for carbon capture and utilization
Desalination techniques have become increasingly common as freshwater resources grow scarcer. While these processes address water supply issues, they also generate high-salinity wastewater, commonly known as brine. The treatment of brine typically relies on direct disposal methods, such as sewer…

Depth-partitioned nitrogen uptake sustained by ammonium in a nitrate-rich reservoir
Thermal stratification in inland waters creates pronounced physicochemical gradients, yet a quantitative, depth-resolved understanding of how these gradients regulate nitrogen (N) dynamics remains lacking. Here, we conducted a two-year, depth-resolved study in a subtropical reservoir, quantifying…

Membrane biofilm reactor (MBfR) enabling optimal H2 delivery and supporting minimal nutrient supplementation to hydrogenotrophic biofilms
The hydrogenotrophic conversion of carbon dioxide (CO2) and hydrogen (H2) gases to methane (CH4), presents a viable alternative to fossil-based natural gas. While different bioreactors have been investigated, the key challenge in these systems is overcoming mass transfer limitations of H2 to…

Polystyrene nanoplastics modulate the transformation of silver ions in the dark: Key role of environmentally persistent free radicals
The co-occurrence of nanoplastics (NPs) and Ag+ has drawn public attention, and NPs-driven transformation of Ag⁺ has been widely documented under sunlight. However, the role of NPs in Ag+ transformation remains poorly understood under dark conditions. We found that environmentally persistent free…

Fusing multi-dimensional features with heterogeneous deep learning for robust dissolved oxygen prediction and control-oriented regulation analysis in complex lakes
Dissolved oxygen (DO) is a fundamental indicator for aquatic ecological health and algal bloom early warning. To address the limitations of existing models in capturing multi-scale features and their reliance on empirical parameter tuning, this study proposes a novel integrated framework. First, a…

Dual-Anode electrochemical strategy enabling struvite-based nutrient recovery coupled with antibiotic degradation
Livestock wastewater typically contains high concentrations of nutrients and antibiotics that are difficult to remove, posing serious environmental risks. This study proposed a dual-anode electrochemical system (DA-EMSP), which simultaneously integrates a boron-doped diamond (BDD) anode for…

Seasonal and depth-dependent dynamics of molecular properties of lake dissolved organic matter during chlorophyll-a production and depletion
The molecular properties of dissolved organic matter (DOM) are closely tied to diverse biogeochemical processes and are fundamental to aquatic ecosystem function. However, how changes in lake DOM molecular composition relate to chlorophyll a (Chl‑a) dynamics remains poorly understood. Here, we…

The crucial role of activated sludge models (ASMs) on wastewater treatment processes: Developments, applications, and future perspectives
Activated sludge models (ASMs), the most widely used mathematical models for biological wastewater treatment, offer a simplified matrix-based representation of pollutant biochemical degradation. As understanding of wastewater treatment mechanisms has advanced, the simplifying assumptions of general…
