Misuse or excessive use of any medicine or product containing nitrates, whether unintentionally or intentionally, can lead to poisoning. Poisoning can result from swallowing, inhaling, or even skin contact. People have been poisoned after drinking nitrate-contaminated rural well water.
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.
Ingestion of nitrite (from potassium nitrite or sodium nitrite sources) has been associated with severe methemoglobinemia in adults and children; in some of these cases, symptoms included hypotension and/or tachycardia ( Gowans 1990; Sevier and Berbatis 1976; Ten Brink et al. 1982 ).
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.
Acute acquired methemoglobinemia is the most important adverse health effect caused by excessive nitrate/nitrite exposure. The known toxic effects from nitrate exposure result from the conversion of nitrate to nitrite.
Sodium nitrite is a powerful oxidizing agent that causes hypotension and limits oxygen transport and delivery in the body through the formation of methemoglobin. Clinical manifestations can include cyanosis, hypoxia, altered consciousness, dysrhythmias, and death.
Symptoms of nitrate/nitrite poisoning include • Bluish skin from a lack of oxygen (likely noticed around mouth/lips first). • Difficulty breathing, • Nausea, diarrhea, vomiting, • Dehydration (from loss of bodily fluids) • Fast pulse, dizziness, weakness, coma and/or convulsions.
