Abstract: In the present study, the relationship between heavy metals (As, Cd, Cr, Cu, Hg, Pb, Ni, Sn and Zn) and
major elements and the location and/geological substrate of 105 river sediments in Flanders was investigated. Factor
Analysis was used to divide the dataset into four components: a first component including clay, organic matter, Na, Ca, K
and Mg, a relationship between Fe, As and Cd, an anthropogenic factor (including Cu, Hg, Pb, Sn and Zn) and finally the
pH and insoluble residue. Regression equations were constructed, using major elements such as Fe and Ca as independent
variables, besides more classical explaining variables such as clay content (< 2μm fraction), organic matter content and
pH. Most heavy metal concentrations could be predicted very well by the independent variables, except Zn, Se and Sn.
The results from this study, performed on a dataset of 105 riverbed sediments, indicate that, besides organic matter and
clay content, other variables such as the total Fe and Ca content can be relevant parameters to predict heavy metal
concentrations in sediments. The more general applicability of the obtained regression equations should be verified, and
the inclusion of Fe and Ca in regression equations that are applied for the standardization of total metal concentrations in
soils and sediments, should be considered.
