  • Environmental occurrence and impacts of arsenic at gold

    Arsenic is a common element in the natural environment and is frequently a significant component in gold deposits of the western United States. Such deposits contain various forms of arsenic: arsenides, sulfides, and sulfosalts. Upon weathering such minerals routinely lower the pH of nearby waters, mobilizing arsenic and other metals. Arsenic may also be mobilized in aqueous environments where
