what does cyanide mean
Cyanides are fast-acting poisons that can be lethal. They were used as chemical weapons for the first time in World War I. Low levels of cyanides are found in nature and in products we commonly eat and use. Cyanides can be produced by certain bacteria, fungi and algae. Cyanides are also found in cigarette smoke, in vehicle exhaust, and in foods such as spinach, bamboo shoots, almonds, lima beans, fruit pits and tapioca.
