Arsenic mine tailings and health - Better Health Channel

Arsenic is a substance found in the environment. It occurs naturally in crushed rock. It is often found near gold deposits and is extracted as part of gold and other mining activities. The waste left over after mining processes is called mine tailings. Mine tailings often look like fine clay or sand and commonly contain raised levels of arsenic.

ARSENIC AND ARSENIC COMPOUNDS - Arsenic, Metals,

1.4. Environmental occurrence. Arsenic is the 20 th most common element in the earth’s crust, and is emitted to the environment as a result of volcanic activity and industrial activities. Mining, smelting of non-ferrous metals and burning of fossil fuels are the major anthropogenic sources of arsenic contamination of air, water, and soil (primarily in the form of arsenic trioxide).
