Understanding built-up land supply-demand coordination in China: A local and tele-coupling perspective

This study utilizes EE-MRIO, LTCCD, and HistGradientBoosting models to analyze China's built-up land supply–demand dynamics from 2012 to 2020, revealing a shift toward tele-coupled supply, an improving but spatially uneven coordination degree, and the critical role of multi-mechanism interactions in guiding future land governance toward stock optimization and interregional equity.

Machine Learning-Based Spatial Mapping, Source Apportionment and Health Risk Prediction of Heavy Metal Contamination in Zanjan Province, Iran

This study utilizes machine learning models and multivariate statistical analysis to map heavy metal contamination sources in Zanjan Province, Iran, revealing that Gradient Boosting and Support Vector Regression effectively predict health risks while highlighting that children face significantly higher non-carcinogenic and carcinogenic risks from cadmium, copper, and nickel exposure compared to adults.

Sinking particle fluxes and nitrogen loss in the eastern tropical North Pacific oxygen deficient zone measured using incubating sediment traps

This study utilizes in situ sediment trap experiments in the eastern tropical North Pacific oxygen deficient zone to reveal an inverted particle flux driven by local cyanobacteria and migrating zooplankton, demonstrating that sinking particles are the dominant source of nitrogen loss and providing the first direct measurements of in situ N2 production rates that align with previous nitrogen deficit estimates.

Indoor Air Quality and Thermal Environment Across Three Leather Footwear Facilities in Agra India

This 27-month study of three leather footwear facilities in Agra, India, reveals that indoor air quality and thermal conditions vary significantly by facility scale and ventilation, with the smallest cottage facility exhibiting substantially higher levels of particulate matter, gases, and CO2 compared to the organized facility, while seasonal factors primarily influenced particulate matter and thermal variables rather than gas-phase pollutants.

When Lakes Remember the Mine Through Multi-Century Evolution of Pit-Lake Hydrology and Closure Stability

This paper synthesizes current understanding of multi-century pit-lake hydrological evolution driven by climate, geology, and geochemistry to advocate for extended simulation periods and adaptive closure strategies that ensure long-term environmental stability and accurate contaminant risk assessment.

Characteristics and atmospheric drivers of hiatus events during Indian summer monsoon progression

This study identifies enhanced dry air intrusion from the northwest as the primary dynamical mechanism driving monsoon progression hiatuses during the Indian summer monsoon, a phenomenon characterized by suppressed convection and moisture transport that has increased in frequency in recent decades.

Baseline radiological assessment of soils in an active limestone mining environment in Ibese southwestern Nigeria

This study establishes a baseline radiological assessment of surface soils in the Ibese limestone mining area of southwestern Nigeria, revealing that while ⁴⁰K levels exceed global averages, all measured radionuclides and associated hazard indices remain below international safety limits, indicating negligible radiological risk to workers and residents.

From Hippocrates to UTCI: Twenty-Five Centuries of Human Biometeorology

This paper traces a continuous, two-millennium tradition of linking atmospheric conditions to human health from ancient civilizations to modern thermal indices like UTCI, arguing that the thermal environment has shaped culture and that contemporary rational indices merely quantify a long-standing insight rather than inventing it.

Integrated debris-flow susceptibility assessment along the Karakoram highway using statistical, multi- criteria, and explainable machine-learning models

This study evaluates debris-flow susceptibility along the Karakoram Highway by comparing multi-criteria decision-making, statistical, and machine learning models using a 104-site inventory, finding that Random Forest achieved the highest accuracy and revealing that topography and precipitation are the primary controlling factors for hazard mitigation in the China-Pakistan Economic Corridor.
