Oral bioaccessibility of metal(loid)s in dust materials from mining areas of northern Namibia
Original language description
Ore mining and processing in semi-arid areas is responsible for the generation of metalloid containing dust, which is easily transported by wind to the surrounding environment. To assess the human exposure to dustderived metalloids As, Cd, Cu, Pb, Sb, Zn, as well as the potential risks related to incidental dust ingestion, we studied mine tailing dust , slag dust and smelter dust from old mining and smelting sites in northern Namibia Kombat, Berg Aukas, Tsumeb. In vitro bioaccessibility testing using extraction in simulated gastric fluid SGF was combined with determination of grain size distributions, chemical and mineralogical characterizations and leaching tests conducted on original dust samples and separated PM10 fractions. Extremely high As and Pb bioaccessibilities in the smelter dusts were caused by the presence of highly soluble phases such as arsenolite and various metal arsenates unstable under the acidic conditions of SGF. The exposure estimates calculated for an adult person of 70 kg
