The current study investigated the degradation of the antibiotic metronidazole (MNZ) from aqueous solutions by means of a photo-Fenton-like process-based system. The efficiency of each variable such as CuCOFe2O4@AC nanoparticles (CFC), UV, and H₂O₂, along with their combined processes, was evaluated to select the most appropriate integrated process. In the second stage, a toxicity test was conducted

In arid and semi-arid regions, water scarcity is a dominant problem where water insufficiency greatly hinders sustainable agricultural development. Another significant challenge is usage of pump stations for lifting irrigation water to elevated lands considering cost recovery of cultivated crops. Egypt, which is a semi-arid region, has been facing challenges due to limited water resources and insufficient

Utilizing aquifers as groundwater storage reservoirs is an effective strategy for water management in water scare regions. The success of managed aquifer recharge (MAR) relies on the assessment and modeling of site-specific hydrogeological characteristics, including groundwater salinity, transmissivity, storativity, slope, soil properties, proximity to water recharge networks and road accessibility

Reference evapotranspiration, which includes the contribution of climatic conditions in potential evapotranspiration, is considered as an important and strategic criterion in water resources management and irrigation designs. Therefore, it is necessary to determine and predict its changes in each region. In this study, using copula functions, the behavior and changes of this component were investigated

In this study, the inactivation of various bacterial strains in a solar illuminated photocatalysis reactor with a titania photocatalyst dispersed in a geopolymer coating is studied. The modular reactor design consists of connected catalyst-coated open water carrying chutes. The cleaning efficiency of the process against chemical and biological water contaminants was evaluated by means of test series

Geogenic contamination of fluoride severely impacts groundwater quality rather than industrial contamination. In this study, MODFLOW and MT3D applications are used to predict the groundwater flow and fluoride transport in Vaniyambadi and Ambur taluk in Tirupathur district. The conceptual model with three-layered aquifer system has been developed using visual MODFLOW flex v6.1 for an area of 955 km2

The authors regret to report that the unit for PFASs' PNEC in Table S3 of the Supplementary Information was mistakenly labelled as ng/L instead of μg/L, leading to inaccurate statements in Fig. 5a, Section 3.4, Section 4.4, the Abstract, and the Conclusions. These occurred due to a miscalculation during data conversion. Below are the details of the errors and corresponding corrections.Download: Download

Anthropogenic pressures like ocean warming, acidification, rising N : P ratios, and marine heatwaves (MHWs) are affecting eukaryotic plankton diversity, though their combined impacts are rarely studied. To address this, we conducted a mesocosm experiment on a North Sea plankton community, testing the influence of a MHW under ambient and future environmental conditions. Using 18S rRNA amplicon sequencing

Brachiopods have been employed for environmental and climatic reconstructions in the near and geological past. Traditionally, one datapoint is obtained per shell, providing time‐averaged bulk signals. However, brachiopods also have the potential to provide time‐resolved information on (sub)annual timescales, but this has been understudied due to difficulties in accounting for brachiopod shell growth

Artificial intelligence has transformed both plankton dynamics and hazardous material management under toxic environments by enhanced hazard prediction in detecting how toxins affect plankton population and potentially uncovering greater depth of ecological insights. In proposed study, nonlinear autoregressive exogenous neural network coupled with Levenberg-Marquardt is efficaciously selected to model

Meandering rivers are widespread fluvial systems, yet surprisingly little is known about the quantity and spatiotemporal patterns of large wood (LW; pieces of dead wood ≥ 1 m long with ≥ 0.1 m in diameter) storage in these environments. This study aims to evaluate the interannual storage and dynamics of LW from 2016 to 2024, focusing on 13 meander bends within a 4 km actively meandering reach of the

Saltwater intrusion in estuarine aquifers through interactions with the saline river water has been shown an important contribution to coastal groundwater salinization. In this study, we performed three-dimensional laboratory experiments to investigate the saltwater intrusion dynamics in estuarine aquifers under tidal conditions. Fully-coupled numerical models were constructed considering surface water-groundwater

This study examines suspended sediment transport affected by flocculation settling in a highly stratified tidal estuary. In situ observation recorded two estuarine front passages during strong‐ebb and flood‐slack tides, respectively. The strong‐ebb front enhanced turbulence, increasing sediment concentrations (~ 5 ppm), macrofloc size (~ 300 μm) and settling efficiency. The surface plume combined with
