The role of inorganic colloids in the transport of toxic metals through the environment

Inorganic colloids are considered as potential transporters of toxic metals in the geosphere. If inorganic colloids are stable and able to adsorb toxic metals they may enhance their apparent solubility. If these colloids are mobile in the aquatic environment they may also enhance the transport of toxic metals. It is therefore of considerable interest to determine the characteristics of inorganic colloids in relation to toxic metal transport. [Continues.]
