“…Moreover, in affected countries, high-As concentrations were found only in some areas. For example, in Burkina Faso, high-As concentrations were found only in the northern region (Smedley et al 2007;Somé et al 2012;Nzihou et al 2013). In Botswana and Ethiopia, only the Okavango Delta and Rift Valley, respectively, seem be concerned with arsenic pollution (Reimann et al 2003;Huntsman-Mapila et al 2006;Rango et al 2010;Dsikowitzky et al 2013;Mladenov et al 2013;Rango et al 2013).…”

“…Recent reports have suggested that two deaths linked to high-As drinking water have occurred in this area (Ouedraogo 2006). Besides, Somé et al (2012) identified that 29.26 and 46.34 % of the population (240 persons) in 20 villages in Yatenga province, Burkina Faso, were affected by melanosis and keratosis, respectively. According to them, this public health problem in Yatenga linked to arsenic is due to drinking water.…”

The review of studies on arsenic in African waters shows that arsenic can be found in high concentrations in both surface water and groundwater. Arsenic concentrations in African groundwater range between 0.02 and 1760 μg L −1 , whilst the level of arsenic in surface water is ranged up to 10,000 μg L −1 . This high level of arsenic in surface water is related to mining operations, agricultural drains, local sediments, disposal, and incineration of municipal and industrial wastes. However, mining activities remain the main source of surface water pollution. They have thereby a strong impact on the concentration of arsenic in the environment. As for groundwater, high levels of arsenic occur in natural conditions. It is due to the presence of iron oxides; sulphide minerals such as pyrite, arsenopyrite, and chalcopyrite; volcanic rocks; and geothermal waters. Few studies in Africa make the link between human health problems and high levels of arsenic in water. Only two articles were found dealing with arsenic remediation. This shows that arsenic, which constitutes a major public health issue in the world, has less interest in Africa although high concentrations of arsenic have been found in both surface water and groundwater in some African countries. Most of the studies carried out on arsenic issues in Africa are dedicated to the characterization and the quantification of the pollution, but studies on the risk to human health and treatment systems are limited. The arsenic issue in Africa needs special attention in order to avoid the problems experienced in some areas mainly in Asia.

“…Groundwater contamination by arsenic levels is up to 1630 μg·L −1 due to mining activities having been measured [3]. The analysis and epidemiological study reported in reference [4] has established a high correlation between the presence of Arsenic in patients' urines and the concentration of Arsenic in their source of drinking water in Yatenga, one of the four provinces of the North region. Solution to this problem was supposed to drill 100 new bore-hole in order to replace access point above national standards.…”

Human health risks assessment were estimated by determining the nature and probability of adverse health effects in the North region’s populations who are now exposed to arsenic from drinking water or will be exposed in the future. Several questions were addressed in this study: what types of health problems may be caused by arsenic from drinking water? What is the chance that people will experience health problems when exposed to different levels of arsenic? What arsenic level are people exposed to and for how long? To answers these questions we have first identified the hazard by evaluating arsenic concentration in thirty-four (34) bore-hole water points among the region based on the assumption of clinical cases related to drinking water. Arsenic concentration ranged from 0 up to 87.8 micrograms per liter. Next we assessed the dose-response of exposure to arsenic. Dose-response relationship describes how the likelihood and severity of adverse health effects are related to the amount and condition of exposure to arsenic. This required us to choose toxicity reference values (TRVs) above which adverse effects may occur for noncarcinogenic and for carcinogenic effects. Exposure factors have been calculated in two scenarios: people from 0 to 14 years old and people from 15 to 70 years. Exposure has been estimated indirectly through consideration of measured concentrations of arsenic in drinking water. This study show that people in the Yatenga, Zondoma and Passore provinces are at very high risk for developing several pathologies such as hyper pigmentation, keratosis, cancer, etc. due by chronic exposure to arsenic in drinking water.

“…Recent studies in the northern part of Burkina Faso showed that more than 50 % of borehole water had arsenic content higher than WHO recommended values (10 ppb). Sanitary damages have also been pointed out including keratosis cases 2. Health implications resulting in consumption of arsenic contaminated water are dermatologic modifications (hyperpigmentation, keratosis) for short term and skin cancer and internal malignancies for long term exposition 3.…”

Determination of Arsenic(III) at a Nanogold Modified Solid Carbon Paste Electrode

et al. 2014

A selective and sensitive electroanalytical method was developed for arsenic determination based on a nanogold (AuNP) modified solid carbon paste working electrode (SCPE) modified in two steps (i) physisorption and (ii) additional electrodeposition of nanogold particles in the presence of iodide. Copper(II) interference was solved by covering the gold layer by a self assembled mono layer (SAM) of glutathione. Using DPASV a linear response of the signal was obtained as a function of As(III) in the concentration range 0.05–20 µM (4–1498 ppb) with a limit of detection of 0.01 µM (0.9 ppb). Sample stirring and degassing were not needed. Application to the determination of arsenic(III) and (V) in underground water samples from Burkina Faso was successfully achieved.
