Area of Science:

  • Occupational Medicine
  • Toxicology
  • Environmental Health

Background:

  • A 40-year-old welder experienced acute mercury poisoning during the disassembly of mercury-covered tubes in acetaldehyde production.
  • Symptoms included nausea, abdominal pain, elevated temperature, headache, and gingivitis, persisting for two weeks prior to hospitalization.

Observation:

  • The patient presented with severe symptoms and extremely high initial urine mercury levels.
  • Neurological examination revealed nystagmus and a positive Romberg test, indicative of mercury's neurotoxic effects.
  • Workplace safety assessments confirmed excessive mercury vapor levels and improper respirator use.

Findings:

  • Treatment with DMPS-Heyl led to symptom resolution and normalization of urine mercury concentrations.
