Contamination of soils with dust fallout from the tailings dam at the Rosh Pinah area, Namibia: Regional assessment, dust dispersion modeling and environmental consequences
Original language description
The dust blown out from the tailings dam appears to be the major environmental threat in the Rosh Pinah town. The degree of regional industrial pollution of topsoil can be best evaluated using the Coefficient of Industrial Pollution (CIP) based on actualand median concentrations of the given contaminants. The bioaccessibility of metals and arsenic in topsoils was tested by a US EPA-adopted in vitro method using a simulating gastric fluid formed of a 0.4Msolution of glycine adjusted to pH 1.5 by HCl addition. Gastric accessible contents of chemical elements in topsoil increase (in % of their total contents in topsoil) in the ascending sequence: Fe (6.2%) -> As (8.6%) -> Cu (23.6%) -> Zn (39.3%) -> Mn (66.7%) -> Pb (85.9%). The evaluation of obtained data on gastric bioaccessibility indicates that a health risk related to soil or dust ingestion should be taken into account only in the case of lead. Dispersion modeling of suspended dust particles (TSP) in the air at Rosh Pinah revealed t
