High-molecular-weight dissolved organic

Additional information is required to determine what is causing this net removal. In the case of iron, research has demonstrated that its solubility decreases with increasing salinity leading to the formation of two types of solids (1) iron oxide minerals, and (2) organic floes. Some iron is also removed by uptake as a micronutrient by plankton. The floes form from the co-precipitation of iron with the high-molecular-weight dissolved organic compounds naturally present in river water.
