Study Notes

Cyanide Toxicity

Cyanide is a highly toxic substance.
Forms include cyanide gas (fastest acting), hydrogen cyanide, and sodium cyanide.
Industrial chemicals can be metabolized into cyanide.
Cyanide disrupts mitochondrial energy production, leading to rapid death.
Inhaling a large amount of cyanide gas can cause death within less than a minute.
An antidote exists, containing nitrite, which binds to cyanide, preventing mitochondrial disruption.
Individuals exposed to large doses often die too quickly for treatment to be effective.
