The article discuses the electrolyte solubility theory for determining the riverine dissolved organic carbon (DOC) flux. It is reported that the organic substances contributing to DOC in surface waters has various origins and range widely in molecular size and chemical characteristics. It is further reported that electrolyte solubility theory explains how declining precipitation ionic strength (IS) has increased the dissolution of thermally moderated pools of soluble soil organic matter (OM).
