Geogenic Contamination: Hydrogeochemical processes and relationships in Shallow Aquifers of Ibadan, South-West Nigeria [PDF]
Bulletin of Geography. Physical Geography Series, 2015 Abstract The result of the spatial analysis as applied to the hydrogeochemical data set in the shallow aquifer of Ibadan provides an insight into the underlying factors controlling hydrogeochemical processes in the area. A total of thirty drinking water samples (six samples each from the five major lithologic formations of the study area)

Integrated machine learning-bayesian receptor modelling framework for uncertainty-aware source apportionment in a non-stationary fluoride-contaminated coastal aquifer [PDF]
Scientific ReportsFluoride contamination in coastal aquifers is difficult to evaluate because its mobilisation is controlled by overlapping and seasonally dynamic non-stationary hydrogeochemical processes influenced by seawater intrusion, lithological heterogeneity ...

Nonhazardous Process for Extracting Pure Titanium Dioxide Nanorods from Geogenic Ilmenite [PDF]
ACS Omega, 2020 Abstract The current rate of industrial production of titanium dioxide, from natural ilmenite, is around 6500 kT per annum. The two main processes used, namely, sulfate and chloride processes, require concentrated corrosive acids and drastic conditions, such as 1000 °C, in open processes, thus contributing to considerable costs and ...

Surface water quality and geogenic process in the quillcayhuanca and shallap streams, huaraz-Peru
International Journal of Hydrology, 2022 This research developed because, given the evidence of previous studies, it is necessary to determine the chemical quality of the water in the Quillcayhuanca and Shallap streams, which surround the city of Huaraz on its way to the Santa River, on the western slope of the Cordillera Blanca in Peru.

Occurrence, Origin and Transformation Processes of Geogenic Chromium in Soils and Sediments [PDF]
Current Pollution Reports, 2016 Weathering of ultramafic rocks has been linked to the occurrence of elevated concentrations of hexavalent chromium (Cr(VI)) in soils, sediments, and groundwater. Ultramafic rocks and the derived serpentine soils and sediments are encountered in populated areas around the world and present high Cr concentrations, with an average of 2200 and 2650 mg/kg ...

An appraisal of the principal concerns and controlling factors for Arsenic contamination in Chile
Scientific Reports, 2023 Although geogenic Arsenic (As) contamination is well-recognized in northern Chile, it is not restricted to this part of the country, as the geological conditions favoring As release to the human environment exist across the country as well, although not ...
