Arsenic poisoning - Wikipedia

Arsenic poisoning is a medical condition that occurs due to elevated levels of arsenic in the body. If arsenic poisoning occurs over a brief period of time symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood. Long-term exposure can result in thickening of the skin, darker skin, abdominal pain, diarrhea, heart disease, numbness, and cancer.

How to Obtain Arsenic | Sciencing

Obtain arsenic as a by-product of mining and refining other metals. Recover the flue dusts produced from copper, nickel and tin, which are high in the arsenides of these metals. Heat them in air to sublimate the arsenic and cool the gas to condense the arsenic back into a solid. This method accounts for most of the arsenic production in the world.
