We investigated how AgNP and ionic Ag undergo phase-transformations in soils.
- class="label">•
88% of AgNP remained persistent after 30 day of aerobic soil.
- class="label">•
In the anaerobic soil, 83% of the spiked AgNP was transformed into Ag2S.

Ionic Ag was sorbed with soil colloids or reduced to metallic Ag.
