Description of key information

Additional information

Research on stability constants indicates generally stronger affinity of the Sn (IV) ion with oxides/hydroxides than with other anions, such as fluorides and chlorides. Tin (IV) oxide is insoluble in water and is expected to partition primarily to the soil and the sediment. Inorganic tin is relatively immobile and nonvolatile, and bioavailability to organisms tends to be low. Release of inorganic tin from benthic sediments is unlikely, except under highly anoxic conditions.
