Mercuric Nitrate

A) TOXICITY: Mercury I chloride is one of the most toxic inorganic mercury salts. Fatalities have occurred from exposure to as little as 0.5 g. The more commonly reported estimated lethal dose of ingested mercury I chloride in an adult is 1 to 2 grams or 10 to 42 mg mercury/kg. For most inorganic mercury compounds, the acute lethal dose for a 70 kg adult is 1 to 4 grams or 14 to 57 mg/kg. There is insufficient data to quantify the amount of inorganic mercury associated with chronic toxicity. Chronic dermal can produce systemic toxicity.

A) TOXICITY: The minimum toxic dose of nitrite is extremely variable; the assessment of the severity of toxicity should be based on clinical findings in the majority of cases. The lowest reported lethal dose of oral sodium nitrite was a 1 g ingestion prior to death in a 17-year-old girl. THERAPEUTIC AND NORMAL DOSE RANGE: The acceptable daily intake of dietary nitrites (excluding infants under 6 months of age) is 0.4 mg/kg. Please refer to "SODIUM NITRITE" management for dosing information.
