Abstract

The dispersal of metalliferous pollution from several spoil heaps produced during 20th century copper mining in the Gruben River valley,in the Namib Desert is examined. More specifically, this study examines the spatial and temporal patterns of metal dispersal and storage and how these vary according to different sedimentary environments. Although the total metal concentrations in the Gruben River valley sediments are extremely high and are in themselves a concern, the small percentage of metals held in the exchangeable phase and the low potential for remobilisation under the arid conditions would suggest that they pose only a minor risk to the environment
