Background

Cyanide compounds are used in a number of industrial processes including mining, electroplating, metallurgy, chemical manufacturing, and photography because these compounds can form stable complexes with a range of metals. Hydrogen cyanide is also a component of tobacco smoke, vehicle exhaust, and is produced by the burning of some plastics. Cyanide salts, such as potassium and sodium cyanide, are also used as rodenticides.
