Phosphorus desorption and isotope exchange kinetics in agricultural soils [PDF]
Soil Use and Management, 2020 Abstract To improve phosphorus (P) fertilization and environmental assessments, a better understanding of release kinetics of solid‐phase P to soil solution is needed. In this study, Fe (hydr)oxide‐coated filter papers (Fh papers), isotopic exchange kinetics (IEK) and chemical extractions were used to assess the ...

Autoradiography of Pi Distribution in Barley Seedlings
Bio-Protocol, 2014 Phosphorus-32 and Phosphorus-33 are radioisotopes of phosphorus. These isotopes are used to trace ionic phosphorus and phosphorus compounds. This protocol is used to follow the movement of inorganic phosphate (PO43-) from a leaf tip to the rest of the ...

Eutrophication-Driven Deoxygenation in the Coastal Ocean [PDF]
Oceanography, 2014 Human activities, especially increased nutrient loads that set in motion a cascading chain of events related to eutrophication, accelerate development of hypoxia (lower oxygen concentration) in many areas of the world's coastal ocean. Climate changes and

Changes in shelf phosphorus burial during the Hirnantian glaciation and its implications [PDF]
Estonian Journal of Earth Sciences, 2023 The Late Ordovician mass extinction occurred during an icehouse interval, accompanied by the glaciation of the supercontinent Gondwana, which was located at the South Pole at that time.

Responses of nitrogen stable isotopes in fish to phosphorus limitation in freshwater wetlands
Knowledge and Management of Aquatic Ecosystems, 2020 Human-induced eutrophication has altered ecological processes in aquatic ecosystems. Detection of ecological changes is a prerequisite for protecting ecosystems from degradation.

New insights into the early Bajocian (Middle Jurassic) carbon cycle perturbation
Sedimentologika, 2023 Mesozoic strata record numerous negative and positive carbon isotope excursions (CIEs). The Middle Jurassic records a negative ~0.5 ‰ CIE at the Aalenian-Bajocian boundary followed by a positive ~1.5 ‰ CIE covering the entire early Bajocian.

Isotopic Fingerprint for Phosphorus in Drinking Water Supplies
Environmental Science & Technology, 2015 Phosphate dosing of drinking water supplies, coupled with leakage from distribution networks, represents a significant input of phosphorus to the environment. The oxygen isotope composition of phosphate (δ(18)OPO4), a novel stable isotope tracer for phosphorus, offers new opportunities to understand the importance of phosphorus derived from sources ...
