Groundwater contaminated with geogenic arsenic (As) is frequently used as drinking water in Burkina Faso, despite adverse health effects. This study focused on testing low-cost filter systems based zero-valent iron (ZVI), which have not yet been explored West Africa for As removal. The active ZVI bed was constructed using small-sized nails, embedded between sand layers. Household filters were tested nine months a remote village relying tube well concentrations of 400–1350 μg/L. Daily...
The semi-arid Sahel regions of West Africa rely heavily on groundwater from shallow to moderately deep (<100 m b.g.l.) crystalline bedrock aquifers for drinking water production. Groundwater quality may be affected by high geogenic arsenic (As) concentrations (>10 μg/L) stemming the oxidation sulphide minerals (pyrite, arsenopyrite) in mineralised zones. These are still little investigated, especially concerning residence times and influence annual monsoon season chemistry. To gain insights...
Small reservoirs (SRs) are essential water storage infrastructures for rural populations of Sub-Saharan West Africa. In recent years, rapid population increase has resulted in unprecedented land use and cover (LULC) changes. Our study documents the impacts such changes on quality SRs Burkina Faso. Multi-temporal Landsat images were analyzed to determine LULC evolutions at various scales between 2002 2014. Population densities calculated from downloaded 2014 data. situ samples collected...
As compared to the Asian lowlands, environmental exposure arsenic (As) in West Africa has received little attention. Recent studies have found geogenic contamination of groundwater many regions Burkina Faso. As-contaminated is used for drinking and increasingly also irrigation staple foods. This study assesses extent which cooking foods Faso influence plant uptake dietary consumption As, respectively. Using a greenhouse experimental setup, we evaluated transfer from water spiked with 0, 100,...
An original multi-parameter system has been used to study the nature of dust in ambient air, particularly total fibers and asbestos fibers, eight areas Institut de Physique Globe Paris (France). These analyses provide a detailed case environmental pollution by at low levels. The levels with length greater than 3 μm, measured real time fiber analyser monitor (FAM), give baseline 2.5 per l., throughout duration sampling. same levels, calculated during periods effective presence staff, are...
<abstract> <bold>Abstract.</bold> Arsenic is a major pollutant of groundwater with evident health impacts on affected populations. Since twenty years, these issues have been highlighted in West Africa. The magnitude arsenic contamination still not sufficiently known countries. There need to predict exactly which areas and kind geology found order give more certainty the implementation new boreholes. main objectives study are to: Measure reliability field measurement technique by comparison...
