The molecular basis for Na/Li exchange is unknown. Li can be transported by the Na pump, anion exchanger (AE1), a background leak, and the Na/Li exchanger. In vivo the intraerythrocyte concentration of Li results from the balance of passive entry, mostly on AE1, and the active extrusion on the Na/Li exchanger. Here we show that erythrocytes have Li-activated PO4 transport that behaves as if it ...

The human response to acute phosphate (PO4) loading is poorly characterized, and it is unknown whether an intestinal phosphate sensor mechanism exists. Here, we characterized the human mineral and endocrine response to parenteral and duodenal acute phosphate loads. Healthy human participants underwent 36 hours of intravenous (IV; 1.15 [low dose] and 2.30 [high dose] mmol of PO4/kg per 24 hours)...

Urbanization and climate change affecting water quality are the most critical problems that humanity has to encounter globally. Undoubtedly, urban bodies heavily contaminated by phosphorus (P). This study aims identify mechanisms efficiency of P sorption process for selected reactive materials (Autoclaved Aerated Concrete (AAC), Filtralite® Nature P, lightweight expanded clay aggregate (Leca®),...

The title compound, strontium trimanganese tris-(ortho-phosphate), was synthesized under hydro-thermal conditions. Its structure is isotypic to that of the lead analogue PbMn(II) 2Mn(III)(PO4)3. Two O atoms are in general positions, whereas all others atoms are in special positions. The Sr and one P atom exhibit mm2 symmetry, the Mn(II) atom 2/m symmetry, the Mn(III) atom and the other P atom ....

Sandusky Bay experiences annual toxic cyanobacterial blooms dominated by Planktothrix agardhii/suspensa. To further understand the environmental drivers of these events, we evaluated changes in the growth response and toxicity of the Planktothrix-dominated blooms to nutrient amendments with orthophosphate (PO4) and inorganic and organic forms of dissolved nitrogen (N; ammonium (NH4), nitrate (N...

The role of two submerged macrophyte species (Ceratophyllum demersum and Potamogeton pectinatus) as biological factor affecting concentrations of P and chlorophyll a concentrations was tested under laboratory conditions. In general, after four weeks exposition, the significant reduction of TP, P-PO4 and chlorophyll a was observed in all experimental variants (aquaria with P. pectinatus, C. deme...

A geochemical proxy for surface ocean nutrient concentrations recorded in coral skeleton could provide new insight into the connections between sub-seasonal to centennial scale nutrient dynamics, ocean physics, and primary production in the past. Previous work showed that coralline P/Ca, a novel seawater phosphate proxy, varies synchronously with annual upwelling-driven cycles in surface water ...

The title compound, poly[(μ2-hydrazine)(μ4-phosphato)iron(III)], [Fe(PO4)(N2H4)] n , was prepared under hydro-thermal conditions. Its asymmetric unit contains one Fe(III) atom located on an inversion centre, one P atom located on a twofold rotation axis, and two O, one N and two H atoms located on general positions. The Fe(III) atom is bound to four O atoms of symmetry-related PO4 tetra-hedra a...

Leachate from municipal landfills of the city is often contaminated heavily, especially for parameters such as organic components, heavy metals, microorganisms. However, leachate also contains amounts of valuable nutrients (e.g. N, P, K) which can be used for agriculture as fertilizers. Precipitated of N and P in the form of struvite (MgNH4PO4.6H2O) might be applied as a technique for removal a...

Growing demands for crops have expanded agricultural production to sandy soils with low available phosphorus (P) content and high P mobility. Knowledge of speciation solubility in such is poorly understood. Here we investigated: i) the clay size fraction soils, ii) pH-dependent soil orthophosphate (PO4–P), iii) particle size-dependent P. The studied loamy sand were organic matter (2.6–7.9 g kg−...
