Cyanide is a toxic chemical that may be introduced into living organisms as a result of natural processes and/or anthropogenic uses (legal or illicit). Exposure to cyanide can be verified by analysis of cyanide or one of its breakdown products from biological samples. This verification may be important for medical, law-enforcement, military, forensic, research, or veterinary purposes. This review will discuss current bioanalytical techniques used for the verification of cyanide exposure, identify common problems associated with the analysis of cyanide and its biological breakdown products, and briefly address the metabolism and toxicokinetics of cyanide and its breakdown products in biological …

Cyanide and nitrosoamines (NAs) are ubiquitous compounds, found in our food and water, either by natural process or through man-made activities. The toxicity of cyanide is exerted by its ability to inhibit metalloenzymes such as cytochrome c oxidase, causing concomitant cascades of biochemical effects such as lactic acidosis, inhibition of ATP production, respiratory seizure, and potential death. Nitrosoamines, on the other hand, undergo biotransformation (metabolic activation in cytochrome P450) in the body to produce unstable intermediates that alkylate DNA, causing mutations, and leading to carcinogenesis. In order to further the advancement of a promising cyanide, cobinamide (Cbi), an LC-MS-MS method …
