A 21-year-old dental assistant attempted suicide by injecting 10 ml (135 g) of elemental mercury (quicksilver) intravenously. She presented to the emergency room with tachypnea, a dry cough, and bloody sputum. While breathing room air, she had a partial pressure of oxygen of 86 mm Hg. A chest radiograph showed that the mercury was distributed in the lungs in a vascular pattern that was more pronounced at the bases. The patient was discharged after one week, with improvement in her pulmonary symptoms.
