Cyanide poisoning inhibits aerobic respiration and therefore increases anaerobic glycolysis which causes a rise of lactate in the plasma. A lactate concentration above 10 mmol per liter is an indicator of cyanide poisoning, as defined by the presence of a blood cyanide concentration above 40 μmol per liter.

Use of hydrogen cyanide as a pesticide or cleaner has been banned or restricted in some countries. [51] Most hydrogen cyanide is used in industrial processes, made by companies in Germany, Japan, the Netherlands and the US. [52] [53] Degesch resumed production of Zyklon B after the war. The product was sold as Cyanosil in Germany and Zyklon in ...
“This antidote will limit damage from gas poisoning caused by sudden fires and can be tested for the treatment of various symptoms caused by gas poisoning,” study co-author Hiroaki Kitagishi ...
Initial autopsy results showed traces of cyanide in the blood of six Vietnamese and American guests at a central Bangkok luxury hotel and one of them is believed to have poisoned the others over a ...
Cyanide antidote kit is a widely used method in treating cyanide induced histotoxic hypoxia. It consists of three different parts that are administered one after the other. The three parts are amyl nitrite, sodium nitrite, and sodium thiosulfate. [3] The nitrites act with hemoglobin to form methemoglobin which binds cyanide.
The most hazardous compound is hydrogen cyanide, which is a gas and kills by inhalation. For this reason, working with hydrogen cyanide requires wearing an air respirator supplied by an external oxygen source. [11] Hydrogen cyanide is produced by adding acid to a solution containing a cyanide salt.
A hydrogen cyanide concentration of 100–200 ppm in breathing air will kill a human within 10 to 60 minutes. [68] A hydrogen cyanide concentration of 2000 ppm (about 2380 mg/m 3) will kill a human in about one minute. [68] The toxic effect is caused by the action of the cyanide ion, which halts cellular respiration.
