WebDec 22, 2024 · The average concentration of dissolved phosphates in unpolluted river waters is equal 30–50 µg P/L [ 28, 29, 30 ], which is 0.6–1.0% of the calculated value of 5 mg P/L. This means that continental runoff contains a very small portion of the labile phosphorus that is formed as a result of organic matter degradation. WebThe global phosphorus cycle has four major components: (i) tectonic uplift and exposure of phosphorus-bearing rocks to the forces of weathering; (ii) physical erosion and chemical weathering of rocks producing soils and providing dissolved and particulate phosphorus to rivers; (iii) riverine transport of phosphorus to lakes and the ocean; and (iv) sedimentation …
