Summary: Epithermal deposits are economically important sources of precious and base metals found in many metallogenic belts globally. However, exploration efforts are hindered by post-mineral cover in prospective districts. Hydrogeochemistry, the study of water-rock interaction, shows promise as an exploration tool in these environments. A case study of the Vaquillas epithermal deposit in northern Chile demonstrates the potential of hydrogeochemistry to identify anomalies and provide valuable insights for exploration in areas with significant post-mineral cover.

Summary: There are concerns about the sustainability of groundwater in Kabul due to rapid depletion. This study used stable isotopic analysis to determine the sources and rates of groundwater recharge. The results showed that precipitation was the main source of groundwater recharge, while river water and irrigation return flow also contributed. The contribution of river water to groundwater recharge varied spatially and with depth. The study highlights the importance of understanding the local water cycle for sustainable groundwater management.

Summary: This paper presents a multi-isotopic study to investigate the origin of saline groundwater in the Cordillera de la Costa, northern Chile. The chemical and isotopic compositions of coastal springs primarily reflect the concentration of salts from atmospheric deposition. The deep saline groundwater is influenced by ancient marine water remnants, mineral alteration, and interaction with volcanic rocks.

Summary: The study found that the evaporation effect in the Badain Jaran Desert gradually increased from south to north. Local precipitation was the main source of recharge for soil water, with deep soil water originating from a mixture of heavy precipitation and shallow soil water. Recharge source and chemical weathering were identified as the two major mechanisms controlling ion concentrations in the soil solution.

Summary: In this study, GIS, remote sensing and geostatistics were used to regionalize the potential natural aquifer recharge and identify suitable managed aquifer recharge (MAR) facilities. The results show that the potential recharge zones are mainly located in areas with high infiltration capacity, such as Koutine, Ksar Chrarif, Sahel El Ababsa, and Mareth. Building MAR facilities in these zones can increase groundwater recharge.

Summary: This study focuses on the replenishment of groundwater in a semi-arid region in Tanzania, showing that focused recharge from ephemeral stream discharges is critical. Groundwater level rises correspond better to pulses of stream discharge from intensive rainfall than from seasonal rainfall. Stable isotope ratios of O and H indicate similarities between groundwater and ephemeral streamflow, both linked to intensive daily rainfall.

Summary: The inter-mountainous region of central Honduras has been facing urban drinking water shortages due to land use fragmentation and rainfall deficits. A 3-year tracer study conducted in the headwaters of the Choluteca River basin revealed the spatiotemporal connectivity between rainfall and groundwater recharge elevations. However, the method's effectiveness was limited by seasonal isotopic variability and rapid infiltration. Mapping critical recharge areas in central Honduras is crucial for improving water regulations and environmental protection.

Summary: It has been found that stable water isotopes can indicate the sources of groundwater recharge. The composition of d18O and d2H reflects the mixture of water at the surface and the origin of moisture during precipitation and infiltration. Therefore, understanding the spatial variability in groundwater recharge and flow paths is crucial for effective aquifer management. This study uses stable water isotopes (d18O and d2H) and groundwater level measurements to investigate groundwater recharge sources and flow paths in the Bilate River watershed, Ethiopia. The isotopic ranges in groundwater samples are more similar to precipitation than river water. The analysis shows that local rainfall is the dominant recharge source for the groundwater. However, there is high enrichment of groundwater isotopes in the northeast and east of the watershed, indicating a mixture of groundwater and surface water due to lake water intrusion.

Summary: The study identifies recharge areas of the Peripheral Aquifer of the Salar de Atacama using isotopic analysis and meteorological data, showing sources of humidity and types of clouds producing precipitation. Summer precipitation is due to deep convection, while winter precipitation mainly comes from the Pacific Ocean. Recharge in the eastern subbasins occurs by precipitation infiltration, while isotopic lighter waters in the Altiplano-Puna Plateau basins do not significantly contribute to the peripheral aquifers of the SdA.

Summary: Human land use and climate change pose threats to ecosystems and natural resources on remote islands like the Azores. By studying paleoecological and paleoclimate records from Lake Funda on Flores Island, it was found that precipitation remained relatively stable between 1000-1400 CE, but the introduction of livestock by early human settlers led to increased primary productivity in the lakes. Evidence of eutrophication was observed, indicating the lasting impacts of human activities on the lake. Despite reforestation efforts, eutrophication continues to be a widespread issue.

Summary: In this study, the effects of wind and wave regimes on the vegetation cover and shoreline position of the Donin tilde os barrier on the NW Iberian coast were examined. It was found that wind stilling was the main factor responsible for the expansion of dune vegetation coverage and seaward shoreline advance. However, energetic winters with strong winds and waves caused erosion and deterioration of vegetation cover, resulting in reversed or stalled advances in shoreline evolution.

Summary: A hydrogeochemical and isotopic study was conducted to investigate the hydrogeological functioning of a small alluvial aquifer in central Chile under conditions of mega-drought and intensive water exploitation. The prolonged mega-drought resulted in reduced rainfall recharge and decreased piezometric levels in the aquifer. Groundwater contamination was not detected, except for elevated nitrate contents attributed to return irrigation. The isotopic and geochemical composition of the aquifer indicated fractionation by evaporation and pyrite oxidation related to copper porphyry mining activities.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
