Changes in hydrodynamic, structural and geochemical properties in carbonate rock samples due to reactive transport [PDF]

open access: yes, 2017
Reactive transport plays an important role in the development of a wide range of both anthropic and natural processes affecting geological media. To predict the consequences of reactive transport processes on structural and hydrodynamic properties of a ...

The integration of geochemical and isotopic approaches for thermo-mineral water characterization: the case of Tebessa (North Eastern Algeria)

open access: yesAcque Sotterranee, 2023
This research aims to assess the hydrogeochemical evolution and the assessment for drinking and irrigation use of the spring water from the alluvial aquifer and major karst aquifer systems in Tebessa (the northeastern part of Algeria).

Prediction of the lifespan of cement at a specific depth based on the coupling of geomechanical and geochemical processes for CO2 storage [PDF]

open access: yes, 2019
The injection of carbon dioxide (CO2) captured from combustion-based processes into underground formations is one of a number of plausible methods to reduce its release into the atmosphere and consequential greenhouse gas warming.

Hydrogeochemical Characterization, and Suitability Assessment of Drinking Groundwater: Application of Geostatistical Approach and Geographic Information System

open access: yesFrontiers in Environmental Science, 2022
Arsenic (As) contamination in drinking groundwater sources is a common environmental problem in Pakistan. Therefore, we collected a total of (n = 81) drinking groundwater samples from various groundwater sources, from two districts’ namely Ghotki (n = 44)

Silicate rock weathering and atmospheric/soil CO2 uptake in the Amazon basin estimated from river water geochemistry: seasonal and spatial variations [PDF]

open access: yes, 2003
Using the data of the CAMREX project (1982–1984) on the water geochemistry of the Amazon river and its main tributaries, it was possible to assess the silicate rock weathering processes and the associated consumption of atmospheric/soil CO2, taking into

A Coupled Geochemical‐Geodynamic Approach for Predicting Mantle Melting in Space and Time

open access: yesGeochemistry, Geophysics, Geosystems, 2022
Geodynamic simulations underpin our understanding of upper‐mantle processes, but their predictions require validation against observational data. Widely used geophysical datasets provide limited constraints on dynamic processes into the geological past ...

Geostatistics as a tool to improve the natural background level definition: An application in groundwater [PDF]

open access: yes, 2017
The Natural Background Level (NBL), suggested by UE BRIDGE project, is suited for spatially distributed datasets providing a regional value that could be higher than the Threshold Value (TV) set by every country.

pH as a Primary Control in Environmental Microbiology: 1. Thermodynamic Perspective

open access: yesFrontiers in Environmental Science, 2018
pH influences the occurrence and distribution of microorganisms. Microbes typically live over a range of 3–4 pH units and are described as acidophiles, neutrophiles, and alkaliphiles, depending on the optimal pH for growth.

Evaluating the influence of lake morphology, trophic status and diagenesis on geochemical profiles in lake sediments [PDF]

open access: yes, 2010
Recent geochemical studies provide evidence that changes in vertical distributions of nutrients in lake sediments are driven by anthropogenic activities, based primarily on trends of increasing concentrations in upper sediment layers.
