Arsenic distribution in mesquite (Prosopis laevigata) and

Arsenic concentrations have been determined in mesquite (Prosopis laevigata) and huizache (Acacia farnesiana) growing on As-rich soils in the semi-arid mining area of Zimapn, Mxico. The elevated As contents in the substrates (up to 32 000 mg/kg) were reflected in the dry weight concentrations of twigs (up to 82.7 mg/kg in mesquite and 225

Arsenic (As) AMERICAN ELEMENTS

The most common form of arsenic used in industry is arsenic trioxide, which may be produced by roasting any of these minerals in air. Roasting the same minerals without oxygen present will produce metallic arsenic. Arsenic is rarely harvested directly, but rather produced as a side product of the mining and purification of other metal ores.
