Copper-binding ligands in the NE Pacific
2018, Marine ChemistryCitation Excerpt :In estuarine waters, terrestrially-derived humic substances (HS) account for a major fraction of the available organic ligands for Cu complexation (Abualhaija et al., 2015; Muller and Batchelli, 2013) and play a key role transporting metals, particularly iron (Fe) to coastal and open ocean waters (Bundy et al., 2015; Laglera and van den Berg, 2009; Misumi et al., 2013). Terrestrial HS are derived from the relatively recent degradation of plant matter (Averett et al., 1994) and are highly aromatic (Ruggiero et al., 1979; Sohn and Weese, 1986), forming organic Cu complexes in seawater with log K'Cu2+L = 12–13 (Kogut and Voelker, 2001; Whitby and van den Berg, 2015). Humic substances are also expected to be important in metal speciation in open ocean waters (Heller et al., 2013; Kitayama et al., 2009), given that 5–25% of dissolved organic carbon (DOC) in the surface ocean is HS (Benner, 2002).
