This document discusses cyanide poisoning. It begins by defining cyanide and listing common sources such as fumigation of ships, electroplating, and the plastic industry. Cyanide poisoning can occur through homicide, suicide, or accidents involving these industries. It is absorbed through inhalation, ingestion, or skin absorption. Clinically, it causes rapid death by inhibiting cellular respiration. Signs include a bitter almond smell, nausea, vomiting, and loss of consciousness. Post-mortem, the body has a bright red color and bitter almond odor. Treatment focuses on giving oxygen, activated charcoal if ingested, and dicobalt edetate as an antidote to prevent death.
