  author={K. Gouws and P. P. Coetzee},
  journal={Water SA},
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… 
Chemical sequential extraction for metal partitioning in environmental solid samples.
A comprehensive review of the sequential extraction schemes for metal fractionation in environmental samples (ie., sediment, soil, sewage sludge, fly ash, etc.), which covers principally the literature published over the last decade is presented.
Evaluation of Heavy Metals Pollution Loadings in the Sediments of the Ave River Basin (Portugal)
Sediment samples from the Ave river basin were collected with the aim of determining metal total pollution contents. Cr, Cu, Fe, Mn, Pb, Zn and VM at 550 °C were determined. Some physico-chemical
Study of application of BCR sequential extraction procedure for fractionation of heavy metal content of soils, sediments, and gravitation dusts
This article deals with the application of original and modified Community Bureau of Reference (BCR) sequential extraction scheme for fractionation of contaminant metallic elements (Zn, Cd, Pb, Ni,
Optimization of a sequential extraction procedure for trace elements in Arctic PM10
The optimized procedure proved successful in avoiding contaminations and suitable to be applied to PM samples having extremely low concentrations, such as samples collected in polar or other remote areas.
Natural and anthropogenic impacts on the geochemical composition and metal speciation of fine sediment in a glacier-fed Canadian river basin
Purpose Surveillance monitoring programs can provide fast, relatively low-cost, synoptic information on key water quality drivers and help inform land management decisions. Here, we evaluate
Chemical Fractionation of Trace Elements in Arctic PM10 Samples
In this study, the information potential of a two-step sequential extraction procedure was evaluated. For this purpose, first of all the elemental composition of Arctic PM10 samples collected in
Use of oligochaete communities for assessment of ecotoxicological risk in fine sediment of rivers and canals of the Artois-Picardie water basin (France)
This study had a purpose to validate different tools based on the oligochaetes for the evaluation of the biological quality of sediments within a surveillance network. Biological data (IOBS index,
