Reactive Processes of Organic Matter in the Amazon River, river (Hedges et al. 1986). The organic matter transported by rivers (ca. 500 × 10. g of organic carbon yr . and ca. 14 × 10. g of organic nitrogen yr.) represents a major link in the global cycles of bioactive elements (Ittekkot et al. 1983; Spitzy and Ittekkot 1991; Meybeck 1993) which modulates the biosphere over geological time.

However, remobilised elements may again be removed from the water column after being released from the sediments (Warnken et al. 2001). As the presence of geochemically reactive phases of trace metals may occur at elevated levels under a wide range of sedimentary conditions (e.g.
