ABSTRACT
Arsenic (As) is a trace inorganic element with its origin being from mineral phases in their crystal lattice and/or adsorbed onto minerals’ surface as inner-or outersphere complexes. The interaction between minerals and water is responsible for the presence of arsenic in the aqueous phases (rivers, stream and sea waters, lakes, and groundwaters). For the rate of water, mineral interaction for As mobilization is dependent on the type of mineral and the biogeochemical conditions like redox potential (Eh), pH, temperature, microbial activity, the speciation and the concentration of metals in the uid, and the ionic strength of the solution. However, once arsenic is released from the solid phases, it can be sorbed onto the mineral phase, precipitate, redissolved, and biointegrate according to the surrounding environmental conditions.
