『Abstract
This is a review of previously published and unpublished results
of research into the occurrence of phosphine (PH3)
in the environment in the form of matrix bound phosphine in soils,
aquatic sediments and sludges (range pg m-3 to ng m-3).
The reviewed data support the hypothesis of the existence of
a small gaseous link in the phosphorus cycle, which could become
important over the long term.
Matrix-bound phosphine in soils can be interpreted as a stationary
state concentration of phosphine between production and consumption.
This phosphine turnover within the soil may be important even
if the stationary state concentration (matrix-bound phosphine)
is small. Under such circumstances, a slow migration process of
phosphine in the interstitial gas sphere of soils is possible.
Such a process would influence the balance of phosphorus in agricultural
and wetland soil.
The detection of easily oxidizable phosphine as a ubiquitous
trace gas in the atmosphere can be interpreted as the residue
of an important turnover of phosphine between widely distributed
emission sources and sinks such as soils and sediments. The atmosphere
can carry gaseous phosphorus to remote places.
