Pd species in soils and a model substance treated with anions was examined. Pd in field soils most soluble compared to Pt and Rh. The outer atomic surfaces of metallic Pd black oxidized with anion treatment. Oxygen in anionic solutions had little effect on species status of metallic Pd. Pd likely to become more bioaccessible when in contact with anions in environment.
