Lethal cyanide inhalation with post-mortem trans-cutaneous cyanide diffusion.
A 27-year-old worker in a metal processing factory was found dead in a basin, sitting in a solution containing potassium dicyano argentate, potassium cyanide, master batch and brightener 'Elfit 73'. The worker was wearing an acid-resisting overall, rubber boots and a simple dust respirator. While the cyanide concentration in the stomach contents was only 0.05 microg/ml, it was 7.7 microg/g in the lung tissue, 6.3 microg/ml in the heart blood and 31 microg/ml in the femoral vein blood. The different concentrations suggest an initial lethal inhalation of cyanide and an extensive post-mortem diffusion of cyanide through primarily non-injured skin of buttocks and legs. The possibility of a post-mortem cyanide diffusion bars from concluding a vital sign from a high cyanide concentration in a blood sample of one single body site.
