Summary: Cyanide is a chemical that is produced naturally by algae, bacteria, fungi, and plants. If cyanide is commercially used it is reacted with other chemicals to form compounds. Hydrogen cyanide is a very popular example of this, used in organic synthesis, metallurgy, electroplating, as a pesticide fumigant, and the production of plastic among other applications. Cyanide is classified by the EPA as a Hazardous Air Pollutant (HAPs). Reaction with water produces hydrogen cyanide gas which is poisonous.
