文摘

Redox effects on Cu, Se, Zn differ in Nile (NDS) & Mississippi (MDS) Deltaic soils. Mobilization of Cu decreased under reducing conditions while Se increased. Release of Se was affected by dissolved organic carbon, Fe, and Mn. Release of Zn was affected by Fe and Mn in the NDS and by Mn in the MDS.
