Detailed explanation-1: -Cyanide is a highly cytotoxic poison[1] and its intoxication may be acute or chronic. Acute intoxication is lethal if not immediately diagnosed and treated within 30 minutes. Mode of poisoning is usually inhalation of smoke, absorption from contaminated skin; accidental oral ingestion is less common.

Detailed explanation-2: -Chronic toxicity is generally thought of as frequent exposures where effects may be delayed (even for years) and are generally irreversible. Chronic toxicity can also result in acute exposures, with long term chronic effects. An example of chronic toxicity relates to cigarette smoking and lung cancer.

Detailed explanation-3: -As such, cyanide poisoning is a form of histotoxic hypoxia, because it interferes with oxidative phosphorylation.
