Oxygen Isotopes of Inorganic Phosphate in Environmental Samples

---

Phosphorus (P) fertilizers are known to increase crop productivity;
however, when applied in excess, it can cause serious environment pollution. Monitoring P pollution in natural environments using stable isotopes has been difficult
because P has only one stable isotope (31P) making the use of P stable isotope tracing
not an option. Radioactive P isotopes (32P and 33P) have been used but its drawbacks
are the short half-life, health risks and safety procedures required to apply them in
agricultural catchments. Phosphorus in organic and inorganic P forms is strongly
bonded to oxygen (O), which has three stable isotopes, providing a system to track
P cycling in agricultural catchments and environment using the stable isotopes of
O in phosphate (δ18O-PO4). In recent years, various studies have indicated that the
analysis of the stable isotopic composition of oxygen (O) bound to P (δ18Op) to better
understand P cycling in the environment, has become a promising tracer (surrogate)
to investigate soil P transformation, plant P uptake and to trace the sources of P from
the soil to water bodies and the environment. The chapter outlines the background
and examples of δ18Op studies in sediments, soils, fresh water, mineral fertilizers and
plants.
