    Arsenic is often found in rocks that contain other valuable metals such as copper and lead. When smelters heat this ore to retrieve the other metals the arsenic is often released into the air as dust. Arsenic is also found in coal and can be released through coalfired power plants or incinerators that burn arseniccontaining products.
