Pollution Characteristics and Health Risks of Heavy Metals in Groundwater of a Chemical Industrial Park

This study evaluates the severe heavy metal pollution and associated health risks in the groundwater of a southern Chinese chemical industrial park, revealing that industrial activities drive widespread contamination with Mn and Co posing significant non-carcinogenic risks while Al contributes to carcinogenic concerns, thereby providing a scientific basis for targeted remediation.

Added value of hourly climate-model ensembles for process-based local-scale water-balance projections

This study demonstrates that using native hourly resolution from convection-permitting climate ensembles, rather than aggregated daily data, significantly alters long-term local water-balance partitioning and drought-stress diagnostics by capturing process-relevant intra-day dynamics, particularly increasing interception evaporation and reducing runoff at forested sites.

Study on pore structure characterization and dynamic evolution in unconsolidated sandstone gas reservoirs

This study characterizes the multiscale pore structures and dynamic evolution of unconsolidated sandstone gas reservoirs in the Tainan Block, revealing that reservoirs combining microfractures with macroporosity yield superior productivity while water invasion and depletion significantly degrade pore connectivity and permeability by shifting the system toward smaller pore-throat structures.

Uranium radioisotopes 234U, 235U and 238U in the environment samples collected near Kowary in the Sudeten Foothills (southwestern Poland)

This study analyzes uranium isotopes (234U, 235U, and 238U) in environmental samples near Kowary, Poland, revealing significant concentration variations and radioactive disequilibrium between 234U and 238U while confirming that natural isotopic ratios remain largely intact, thereby demonstrating the analytical potential of combining alpha and mass spectrometry for investigating uranium geochemistry in post-mining environments.

Heavy Metal Pollution Characteristics in Campus Dust from Vocational and Comprehensive Universities in a Developing City, East China

This study investigates heavy metal pollution characteristics, sources, and health risks in indoor and outdoor dust from vocational and comprehensive universities in East China, revealing moderate zinc pollution and tire wear or vehicle exhaust as primary sources while confirming no significant non-carcinogenic or carcinogenic health risks to students and staff.

Seasonal Heavy Metal Contamination and Ecological Risk in the Mwambashi–Kafue River System, Zambia

This study reveals that the Mwambashi–Kafue River system in Zambia suffers from significant seasonal heavy metal contamination, particularly copper, which accumulates primarily in sediments and poses considerable ecological risks driven by mining-related activities.

River suspended sediment response to tropical cyclone precipitation in the Eastern United States

This study utilizes remote sensing and precipitation data to demonstrate that tropical cyclones in the eastern United States drive disproportionately high riverine sediment flux compared to non-cyclone events, revealing fundamentally different sediment response mechanisms that are critical for infrastructure planning and water quality management.

Explainable GeoAI Framework for Groundwater Pollution Prediction, Vulnerability Mapping, and Sustainable Water Intelligence in Semi-Arid Regions

This study presents an integrated GeoAI–ML–XAI framework for semi-arid regions that utilizes high-accuracy machine learning models and novel explainability metrics to predict groundwater pollution, identify key contamination drivers, and generate sustainable, interpretable vulnerability indices for improved environmental decision-making.

Firming weather dependent renewable generation yields single digit system level energy returns

This study demonstrates that while weather-dependent renewable sources like solar and wind show favorable installation-level energy returns, expanding the system boundary to include the necessary firming infrastructure (such as storage, overbuild, and backup) drastically reduces overall energy returns and increases carbon emissions, indicating that reliable decarbonization requires firm low-carbon generation with a sufficient net-energy surplus.
