Redox chemistry in the phosphorus biogeochemical cycle.

Interactive comment on “Glacial-interglacial variability in ocean oxygen and phosphorus in a global biogeochemical model” by V. Palastanga et al

This model was designed to look at the P cycle and therefore, the most important results are the changes in the P cycle between the different simulations. The removal of P from the ocean is messy it can be removed in multiple phases, which have complex relationships with the redox and biotic conditions near the sediment-water interface. Therefore, the discussion should really focus on these rem...

Review of interactions between phosphorus and arsenic in soils from four case studies

Arsenic is a non-essential element that poses risks in many environments, including soil, groundwater, and surface water. Insights into the environmental biogeochemistry of As can be gained by comparing As and P reaction processes. Arsenic and P are chemical analogues, and it is proposed that they have similar chemical behaviors in environmental systems. However some chemical properties of As a...

Beyond carbon and nitrogen: how the microbial energy economy couples elemental cycles in diverse ecosystems

www.frontiersinecology.org © The Ecological Society of America A organisms have to make a living by harnessing energy, collecting nutrients, and expelling waste. The joining together, or coupling, of elemental cycles occurs when elements required for biosynthesis are assimilated into microbial, plant, and animal biomass, and again when that biomass is decomposed; in both cases, elements cycle i...

The Effect of Coinage Transition Metal (Cu, Ag, Au) Substitutions on Two-electron Redox Potential of Quinones

Quinones are a class of compounds which have widespread importance in chemistry, biology and medicine. Because of their appropriate performance in electron transferring rate, quinones are among the most applicable mediators in biosensors. Recently, the effects of different non-metal substitutions on redox potential of quinone have been investigated to design suitable mediators for different ele...
