Why is cyanide a problem?
Cyanide is highly toxic, and can result in substantial environmental impacts and public health risks if released into the environment. Cyanide spills have resulted in major fish kills, contaminated drinking water supplies and harmed agricultural lands.
Why is cyanide used in mining?

What is the major effect of cyanide?

How much cyanide is in an apple?
A lethal dose of hydrogen cyanide may be around 50–300 mg. Apple seeds have the potential to release 0.6 mg of hydrogen cyanide per gram. This means that a person would have to eat 83–500 apple seeds to develop acute cyanide poisoning.
