Arsenic is a metalloid trace element widely distributed throughout the natural environment (i.e. air, water and soil). It is the 40th most abundant element in the Earth's upper continental crust (Hu and Gao, 2008) being one of the most hazardous toxic elements for the ecological and human health (Chappell et al., 1999; Reimann et al., 2009).Web
Mining and smelting of these minerals create environmental hazards of arsenic leaking into groundwater and surface water from slag pits, waste dumps, extraction basins, and mines.
