Purifying phosphorus When phosphorus is mined out of the ground, it is in the form of phosphate, a mineral whose basic unit comprises one atom of phosphorus bound to four oxygen atoms. About 95 ...

This is an artist’s impression of habitable Mars Daein Ballard / CC BY-SA 3.0 We know that at different points in Earth’s history, it had very different oxygen levels. There seem to have been times at ...

The oxygen isotope composition of phosphate (δ 18 O p) offers a powerful tracer for elucidating the complex pathways of phosphorus cycling in both terrestrial and aquatic ecosystems. By analysing the ...

The recovery of Lake Sammamish from wastewater diversion in 1968 was delayed 7 years because sediment phosphorus release remained high until the mid-1970s. Marked reductions in phosphorus and ...

The planet’s long-standing natural “thermostat” is being outpaced by an feedback loop process involving algae, phosphorus, and oxygen that’s supercharged by anthropogenic climate change.

In order to improve the trophic state of Lake Sempach, a eutrophied lake in central Switzerland, its external phosphorus (P) load has been decreased and its hypolimnion has been artificially ...
