Determination and partitioning of heavy metals in sediments of the Vaal Dam System by sequential extraction
@article{Gouws1997DeterminationAP, title={Determination and partitioning of heavy metals in sediments of the Vaal Dam System by sequential extraction}, author={K. Gouws and P. P. Coetzee}, journal={Water SA}, year={1997}, volume={23}, pages={217-226} }
The partitioning of 12 heavy metals in sediments of the Vaal Dam system was determined by applying a sequential extraction procedure. Environmental risks associated with the potential remobilisation of these metals, the capacity of the sediment to continue functioning as a sink and the possible origin of the metals were assessed. Despite the fact that the water level was at record lows; ca, 13% in the Vaal Dam. the extractable metal content of the sediments was low indicating a relatively…
