Araújo, M.F.D.; Bernard, P.C.; Van Grieken, R.E. (1988). Heavy metal contamination in sediments from the Belgian coast and Scheldt estuary. Mar. Pollut. Bull. 19(6): 269-273

Sixty-two samples of total sediments and the separated clay/silt fractions were analysed by the energy-dispersive X-ray fluorescence spectrometry to evaluate the pollution level and the trends in samples collected along the Belgian coast over a period of 6 yr and at four stations located in the Scheldt estuary where two of these were sampled periodically for 4 yr. Three correction methods for grain size effects were applied, either to the bulk sediment samples or to the clay/silt size fractions, and the results were compared. Local variations on the concentrations in some of the elements determined were used to establish whether they result from an anthropogenic or natural origin. The level of pollution was assessed as a function of the location, sampling date, and depth.
