Whole‐crop harvestable chicory for the phytoextraction of copper from wine‐growing soils and its use in animal feed

Abstract Background Since 2018, European Union regulations have reduced copper (Cu) doses in viticulture to combat fungal diseases, but Cu continues to accumulate in soils, potentially harming soil organisms. The aim of our study was to reduce the Cu content of soils by means of...

The WoKaS-Iso database: workflow for a global compilation of oxygen-18 and deuterium records in karst springs and cave drip water for enhanced understanding of karst systems

For analysing karst hydrogeological systems, observations of karst springs and cave drips are considered indispensable. In addition to hydrometric observations, knowing the oxygen and hydrogen stable isotope ratios has improved the understanding of vadose zone and aquifer dynamic...

How can prospective life cycle assessment support the eco-design of an innovative battery-grade lithium carbonate production process?

The transition to low-carbon energy systems drives increasing lithium demand, making alternative recovery technologies essential for long-term supply resilience. This study shows how eco-design principles guide the identification of the most environmentally-friendly configuration...

Combined Impacts of Climate and Land-Use/Land-Cover Changes on the Flow Regime and Ecological Diversity in the Songkhram River Basin, A Tributary of the Mekong River

Abstract Climate change (CC) and land-use/land-cover (LU/LC) alterations are among the most pervasive drivers of hydrological and ecological change in river basins worldwide, yet their combined impacts on fluvial ecological diversity remain insufficiently quantified, particularly...

Experimental constraints on pre-eruptive conditions at Nabro volcano, Eritrea, 2011, and implications for sulphur emissions

Abstract We present new experimental constraints on the pre-eruptive magma storage conditions at Nabro Volcano, Eritrea, prior to its 2011 eruption, and discuss the implications for sulphur emissions. We find that the magma was likely stored in the shallow crust prior to eruption...

Assessment of mineralogical and chemical quantification of spodumene ore (Li) using a rapid compact XRF–XRD analyzer on-site: Impact of sample preparation on analytical results

Ore variability remains a major challenge for grade control and metallurgical performance, emphasizing the need for detailed mineralogical characterization to support process optimization and quantitative assessment of ore deportment. This study evaluates a combined XRF-XRD appro...

Regional risk assessment Part II: identification of diffuse soil contamination hotspots

Abstract Diffuse soil contamination represents a widespread environmental issue, resulting from multiple low-intensity and spatially dispersed sources, including atmospheric deposition, agricultural practices, traffic emissions, and legacy industrial activities. Unlike point-sour...

Magma-induced midcrustal flow and high-temperature metamorphism: Insights from the early Mesozoic Yunkai massif (South China) and tectonic implications

The way in which partial melting weakens the middle continental crust and triggers lateral flow is fundamental to understanding orogenic processes, yet the specific roles of magmatic heat and deformation remain debated. We addressed this issue through an integrated study of the e...

Impact of extreme rainfall on triggering conditions and susceptibility for shallow landslides: a case study in the Alpes-Maritimes region (France)

Abstract. Prediction of shallow landslides at the regional scale generally relies on statistical analyses of landslide inventories. Rainfall-duration thresholds and susceptibility maps are among the most common approaches to anticipate future landslide occurrences. However, the o...

Termites play a crucial role in forming major tropical soils: insights from a deep Ferralsol

Abstract Soil bioturbation is increasingly recognized as a key driver of pedogenesis in tropical ecosystems, influencing above- and below-ground biodiversity, nutrient cycling, and aggregate stability across different spatial and temporal scales. This ecological process may play...
