From November/December 2024 Grain Journal Issue. WebSep 15, 2024 · Conclusion: Phosphine should be/is considered to be an integral member in phosphorus biochemical cycle as it is found to be formed from the reduction of phosphites/hypophophosphites (important members in PBC). About 10% of the phosphorus produced in the atmosphere from PBC is PH 3.
