Solubility, migration, and bioavailability of plutonium is lacunar because experimental evidences are missing. We report here on X‐ray Absorption Spectroscopy of plutonium in natural seawater. The observed valence state is +IV and its speciation corresponds to PuO 2 type colloids. Furthermore, aging of the solution shows a gradient of ordering from hydroxide colloidal species to more crystalline PuO 2 colloids.
