Contamination of soils with dust fallout from the tailings dam at the Rosh Pinah area, Namibia: Regional assessment, dust dispersion modeling and environmental consequences

Popis výsledku v původním jazyce

The dust blown out from the tailings dam - and to a lesser extent from the ore treatment plant - appears to be the major environmental threat in the Rosh Pinah town. The amount of suspended dust particles in the air (TSP) monitored on the surface of thetailings dam ranges between 8 and 84 mg m(-3). The air contains (in mu g m(-3)) high amounts of Zn (median: 792), Pb (median: 412), Mn (median: 163), and Cu (median: 42), and lesser amounts of As (median: 5) and Cd (median: 2). Sampling of topsoil together with reference sampling of subsurface soil at a depth of 80-90 cm revealed that the shape of the dust contamination halo is elongated northwestward according to the prevailing direction of winds during summer. The eastern and northeastern parts of theRosh Pinah town are affected by dust fallout. The factor analysis of data acquired from topsoil revealed two factors governing the source and the nature of individual components: (a) "tailings specific factor" grouping predominantly CO2
