“…The chemistry of trace metals and their interaction with natural ligands (such as, dissolved organic matter) are well studied in aquatic system as reflected by the large numbers of publications available in the literature (Achterberg and Braungardt, 1999;Bayen et al, 2006;Chakraborty, 2010;Chakraborty and Chakrabarti, 2008;Chakraborty et al, 2007;Chakraborty et al, 2009;Gopalapillai et al, 2008;Groschner and Appriou, 1994;Guthrie et al, 2005;Nicolau et al, 2008). However, the knowledge of speciation of trace metals and their interactions with heterogeneous binding sites present in sediments are not well understood.…”

“…Combination of two or more appropriate methods and techniques, with their associated measurement timescales and detection windows, may provide better information of metal speciation in natural systems (Chakraborty, 2010;Chakraborty et al, 2009). It is of clear interest in this section to identify the key factors which control La speciation in coastal and estuarine sediments by combining the data obtained by two different extraction methods.…”

“…The kinetic model developed by Olson and Shuman [49] has been adapted [50][51][52][53][54][55] to study the dissociation of a metal complex, ML, where M is a metal ion and L is a macromolecular, polyfunctional complexant, such as a humic substance, having binding sites of different chemical affinities (the charges on M and L have been omitted for simplicity). In the complexant L, the metal M is bound to multiple sites in L, all of which dissociate independently and simultaneously at a rate that depends on the nature of the functional group, its position on the macromolecules, and the residual charge.…”
