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
