Thee Role of Sedimentation in Reducing Organic Carbon

Organic carbon in water sources is broadly classified into two fractions: disolved organic carbon (DOC) and specilate organic carbon (POC). POC included deploid s larger context, cell fragments, detritus, and living organisms such as algae bacteria. DOC contexes smaller context a precursor for products coulvic acids, which are often recalcitrant. Sedimentation diredirectly C poby physical settling.
