WebMar 15, 2024 · Phosphates, Sewage, Stable isotopes Abstract Identifying phosphorus (P) sources is critical for solving eutrophication and controlling P in aquatic environments. Phosphate oxygen isotopes (δ 18 O p) have been used to trace P sources. Although phosphorus (15P) has 22 isotopes from P to P, only P is stable; as such, phosphorus is considered a monoisotopic element. The longest-lived radioactive isotopes are P with a half-life of 25.34 days and P with a half-life of 14.268 days.
