Cyanide can exist in several chemical compounds and physical forms: liquid, gas, powder, crystals/salts or briquettes. All chemical forms of cyanidehydrogen cyanide (gas), sodium cyanide (liquid or solid) or calcium cyanide (liquid or solid)have a faint, bitter, almond-like odor.
Cyanide is widely used in industry, found in certain plants and household products and is produced by the incomplete combustion of common materials such as wood, paper, plastics and synthetics that are commonly found in building materials, interior furnishings and in transportation vehicle interiors such as planes, buses and ships.
The United States uses an estimated 1.838 billion pounds of cyanide (2004) annually for various industries including gold and silver mining, electroplating, production of plastics, synthetic fibers, pigments and dyes, and pesticides. Cyanide is primarily used as an intermediary in the production of other materials.
