OVERVIEW. Cyanide is a potentially lethal toxic agent that can be found in liquid and gaseous form. First discovered in 1786 by Scheele, who extracted it from the dye Prussian blue – and promptly died from exposure to the vapours. Average lethal dose of prussic acid (hydrogen cyanide, HCN) taken by mouth between 60 and 90 mg (adult)
Dec 11, 2018 · According to Jackson and Logue, blood is the ideal matrix for testing for cyanide since cyanide binds to hemoglobin on red blood cells (RBCs) and there is a direct correlation between toxic effects and blood cyanide concentration . Since cyanide binds primarily to RBCs, detection in the plasma and serum is minimal.

First isolated in 1782, cyanide is a compound composed of carbon atom triple-bonded to a nitrogen atom (C≡N). Cyanide is a naturally occurring chemical can be produced by certain types of bacteria, fungi, and algae and found in several types of plants, seeds, and fruit stones, including bamboo, cassava, bitter almonds, apples, and peaches.
Aug 14, 2024 · Following ingestion, cyanide is found in the stomach, with lesser amounts found in the spleen, blood, liver, brain, and kidney; it is found in the lung, blood, brain and kidneys following inhalation .
Furthermore, cyanide was found to attach more readily to plasma albumin than to hemoglobin (McMillan and Svoboda 1982). It was suggested that hemoglobin in erythrocytes binds cyanide molecules, but does not play any role in their metabolism. Some authors argue that cyanide in red blood cells may be biologically active . In addition, it is known ...

Feb 13, 2023 · Cyanide is a rapidly acting substance that is traditionally known as a poison. Hydrogen cyanide was first isolated from Prussian blue dye in 1786, and cyanide first extracted from almonds around 1800. Cyanide can exist as a gas, hydrogen cyanide, a salt, potassium cyanide. Natural substances in some foods such as lima beans, almonds can release cyanide. Cyanide is also found in manufacturing ...

Jan 1, 2015 · In the blood, most cyanide is concentrated within red blood cells, making red blood cell cyanide concentrations many times higher than concentrations in plasma. The higher levels of cyanide found in red blood cells are more easily measured, and red blood cell cyanide concentrations correlate with concentrations in plasma and tissue.
