In aqueous environments, nitrate and nitrite salts such as sodium nitrate, potassium nitrate, sodium nitrite, and potassium nitrite rapidly ionize. Sodium nitrate is approximately 27% sodium and 73% nitrate. To determine a nitrate dose from a sodium nitrate source, the quantity of sodium nitrate is multiplied by the nitrate proportion (0.73).
Oct 27, 2022 · Sodium nitrite causes increased methemoglobin, resulting in systemic hypoxia, metabolic acidosis, and cyanosis. Since sodium nitrite is a preservative, the ingestion of foods containing an excessive amount of this substance can also cause acute intoxication up to death.
The known toxic effects of nitrate exposure result from the conversion of nitrate to nitrite [Hord 2011; ATSDR 2004]. The effects of nitrite (NO 2 -) are the same whether nitrite containing compounds are ingested or inhaled, or nitrite is produced in vivo from nitrate.
This Public Health Statement summarizes the Agency for Toxic Substances and Disease Registry’s (ATSDR) findings on inorganic nitrate and nitrite, including chemical characteristics, exposure risks, possible health effects from exposure, and ways to limit exposure.
