Arsenic Toxicity Case Study Where is Arsenic Found

Arsenic occurs naturally in the earths crust, and much of its dispersion in the environment stems from mining and commercial uses. In industry, arsenic is a byproduct of the smelting process (separation of metal from rock) for many metal ores such as . cobalt, gold, lead, nickel, and ; zinc.
