Statistical evaluation of fluoride contamination in groundwater resources of Santiago del Estero Province, Argentina.
Highlights Fluoride concentration in groundwater from Santiago del Estero was determined. pH, conductivity,TDS, chloride, hardness and alkalinity were monitored. Multivariate methods of principal component analysis and clusters were applied for evaluating the fluoride content. Abstract This study investigates the suitability of statistical techniques for evaluating the fluoride content and the groundwater quality from Robles Department […]Argentina
Hydrogeochemical controls on the mobility of arsenic, fluoride and other geogenic co-contaminants in the shallow aquifers of northeastern La Pampa Province in Argentina.
Highlights Shallow groundwater in NE La Pampa province is saline and has elevated arsenic, and fluoride levels Weathering of carbonate minerals controls groundwater chemistry During dry seasons trace elements accumulate in discharge areas due to evaporation Abstract Elevated Arsenic (As) and Fluoride (F) concentrations in groundwater have been studied in the shallow aquifers of northeastern […]Argentina Water Treatment
Occurrence and distribution of high arsenic in sediments and groundwater of the Claromecó fluvial basin, southern Pampean plain (Argentina).
Abstract Occurrences of high arsenic (As) in sediments and groundwaters were investigated in the Claromecó fluvial basin, southern Pampean plain, Argentina. This investigation includes sedimentology, mineralogy, and hydrogeochemistry of the Neogene and Quaternary aquifers to determine possible sources and transport mechanisms for As in the Claromecó basin. Characterization of the sediments revealed homogeneous mineralogy in […]Argentina
Geochemical occurrence of arsenic, vanadium and fluoride in groundwater of Patagonia, Argentina: Sources and mobilization processes
Highlights The As, V and F presence in the groundwater of Peninsula Valdes is due to a natural origin. Volcanic particles and iron oxides of the Miocene sediments shows the highest As concentrations. Groundwater pH conditions the volcanic shards dissolution and therefore the As, V and F release. Abstract Contamination of groundwater in different parts […]Argentina Volcanoes
Evaluation of exposure to fluoride in child population of North Argentina
Abstract: Fluoride is an important element for humans. It inhibits initiation and progression of dental caries and stimulates bone formation. However, excessive intake may lead to the appearance of dental and/or skeletal fluorosis and a decrease in intellectual coefficient in child populations. This study evaluates exposure to fluoride in the child population of Chaco province […]Argentina
