Arsenic Toxicity Case Study Where is Arsenic Found

Oct 01, 2009Arsenic 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.

6. What are the effects of arsenic on the environment?

In general, inorganic forms of arsenic are more toxic to the environment than organic forms and, among inorganic forms, arsenite is more toxic than arsenate. This is probably because the way in which the various forms are taken up into the body differs and once taken up, they act in different ways in the body.
