Abstract

A 35-year-old man ingested an unknown amount of sodium azide and died within 2 h. The postmortem interval was 3 days. No alcohol or drugs were found in the blood and urine. Azide was derivatized in the peripheral blood, urine, and vitreous fluid with propionic anhydride. A portion of the headspace was injected onto a gas chromatograph with a nitrogen-phosphorus detector. Azide was quantitated in the peripheral blood (1.1 μg/mL), urine (7.5 μg/mL), and vitreous (43 μg/mL). The vitreous appears to be a better fluid for azide screening because of slower degradation.

Keywords: azide fatality; forensic science; gas chromatography-nitrogen-phosphorus detector; poison; suicide; toxicology.
