Cyanides are infamous for their highly poisonous properties. Accidental cyanide poisoning occurs frequently, but occasionally, intentional poisonings also occur. Inhalation of fumes generated by fire may also cause cyanide poisoning. There are many limitations in direct anal. of cyanide. 2-Aminothiazoline-4-carboxylic acid (ATCA), a cyanide metabolite, seems to be the only surrogate that is being used in the detection of cyanide because of its stability and its cyanide-dependent quality in biol. matrix. Unfortunately, the toxicokinetic study on diverse animal models suggests significant interspecies differences; therefore, the attempt to extrapolate animal models to human model is unsuccessful. The aim of the present study was to evaluate the use of ATCA as a forensic marker of cyanide exposure. For this purpose, postmortem materials (blood and organs) from fire victims and cyanide-poisoned persons were collected. The distribution of ATCA in organs and its thermal stability were evaluated. The variability of cyanides in purified sample and in the context of their long-term and higher temperature stability was established. The presence of ATCA was detected by using LC-MS/MS method and that of cyanide was detected spectrofluorimetrically. This is the first report on the determination of ATCA distribution in tissues of fire victims and cyanide-poisoned persons. It was found that blood and heart had the highest ATCA concentrations ATCA was observed to be thermally stable even at 90°. Even though the cyanide concentration was not elevated in purified samples, it was unstable during long-term storage and at higher temperature, as expected. The relationship between ATCA and cyanides was also observed Higher ATCA concentrations were related to increased levels of cyanide in blood and organs (less prominent). ATCA seems to be a reliable forensic marker of exposure to LDs of cyanide.
