A rare fatal case of self-poisoning with nitrobenzene following oral ingestion is reported. On presentation to the hospital, severe methemoglobinemia (70%) was observed in an 82-year-old male who had ingested 250 mL of an unknown substance in the previous 24 h. ⋯ We detected that the blood contained 3.2 microg/mL of nitrobenzene. The determination of nitrobenzene was performed using the combination of GC-FID for screening analysis and quantitation and GC-MS for confirmation of the obtained results.
