title: Massive oral ingestion of elemental mercury.
abstract: A 42 year old male, while repairing a sphygmomanometer, intentionally ingested an estimated 3 kg (220 mL) of metallic mercury. During admission, only tremor, irritability, forgetfulness and fatigue were noted. There were no obvious gastrointestinal or hepatic complications. Blood and urine mercury levels were significantly elevated. Most of the metallic mercury was cleared from the gut within 10 days. A few months later, hepatic dysfunction with jaundice developed. Serial investigations did not suggest a viral etiology or alcoholism. Liver function tests and blood and urine mercury levels returned to normal over the next 10 months. The observation suggests that massive and prolonged retention of metallic mercury may facilitate the conversion of metallic, elemental mercury to divalent mercury and its subsequent absorption with development of hepatic dysfunction.
