Summary according the environmental distribution of cobalt and cobalt compounds, as given in CICAD 69 (WHO 2006)

"Cobalt and inorganic cobalt compounds are nonvolatile. Therefore, they are released into the atmosphere in particulate form." "Ultimately, the final repository for cobalt is soil and sediment." "Released into water, cobalt may sorb to particles and settle into sediment or sorb directly to sediment." "The partition coefficient, KD, of cobalt ranged from 0.2 to 3800 l/kg in a wide variety of soils.
