This study of the Gnikpière artisanal gold mining site in Burkina Faso reveals that despite high awareness of mercury risks among miners, the widespread use of unprotected handling and open-air burning practices has resulted in significant soil contamination, particularly at milling sites, while water samples remained below detection limits.
This study demonstrates that the Gaussian Process Regression (GPR) model, when applied to bias-corrected CMIP6 data at a 6-month scale, effectively forecasts meteorological drought in Iran's semi-arid Karkheh Hydrosystem, revealing that while longer time scales show wetter trends, the pessimistic SSP585 scenario poses significantly higher risks for extreme drought events compared to the more stable SSP126 scenario.
This study utilizes multi-source satellite data and Google Earth Engine to analyze the spatiotemporal dynamics of air pollutants and land surface characteristics in Riyadh from 2018 to 2025, revealing that while seasonal meteorological conditions and urban greening influence pollution patterns, emission intensity and atmospheric processes remain the dominant controlling factors.
This study reveals that in the shallow-soil Chaohe River catchment, agricultural nitrogen is primarily enriched in surface layers with significant leaching vulnerability due to limited deep storage capacity, driven mainly by fertilizer inputs and mineralization while being positively regulated by soil sand content and negatively by pH.
A six-week mesocosm experiment demonstrates that climate-driven increases in nutrient runoff can promote the development of filamentous macroalgal mats in shallow coastal ecosystems, effectively overwhelming the biological control provided by abundant benthic grazers like *Hediste diversicolor*.
This study introduces a novel experimental setup using the Transient Plane Source technique to directly measure the thermal conductivity of water-saturated sandstone at elevated temperatures, revealing a temperature-dependent decrease in conductivity and highlighting the limitations of relying on dry-state data or mixing models for geothermal reservoir assessments.
This paper presents a large-scale review of over 2,000 U.S. Environmental Impact Statements using a customized Retrieval-Augmented Large Language Model pipeline to create a centralized ecology data store that reveals regional and sectoral trends in ecological tool usage and demonstrates its practical utility for environmental planners, legal practitioners, and researchers through specific case studies.
This study reveals that the South Indian Peninsula has experienced a significant warming-driven intensification of Heat–Wet Alternations since 1981, characterized by increased frequency and non-stationary variability linked to planetary warming and reorganized climatic modes, while also demonstrating the efficacy of a machine learning model in predicting these compound extremes based on antecedent local heat.
By analyzing valley network elevations against transient groundwater simulations, the study concludes that ancient Martian runoff was only weakly coupled to regional groundwater recharge, implying that surface water rarely reached aquifers and caution is needed when comparing surface and subsurface hydrologic evidence.
This study presents the first continent-wide map of the Antarctic Ice Sheet's internal structure, revealing that its stratification and anisotropy are shaped by thermomechanical coupling, specifically the onset of dislocation creep and basal temperature variations, which collectively govern the ice sheet's dynamics and future evolution.
