Summary:Concentrations of metals associated with both dissolved and colloidal organic matter decrease with depth, although the concentration of organic matter in the interstitial waters increases with depth. The distribution pattern may be explained as due either to release of organically-bound metals during diagenesis to form insoluble sulphides or to dilution of metal-rich material that may form only near the sediment surface by diagenetically-produced metal-poor organic matter. Diffusion of organically-associated metals in interstitial waters is probably not a major factor in metal transport, but the metal-organic complexes may be important in the diagenetic processes in which the activity of benthic animals is a significant transport mechanism.
