Feb 23, 2024 · This compound is at the heart of why nitrates and nitrites are considered toxic. Nitrosamines are a carcinogen, or a cancer-causing substance. They are found everywhere in our environment,...
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.

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 ).
Mar 17, 2022 · Sodium nitrite toxicity is capable of causing severe methemoglobinemia with high mortality. Prompt identification is crucial. We discuss the important implications in regard to media coverage, imitative suicide, and accessibility of sodium nitrite.
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.
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.

Hematologic Effects. Acute acquired methemoglobinemia is the most important adverse health effect caused by excessive nitrate or nitrite exposure. Methemoglobinemia inducers also work through other mechanisms outside of nitrate and nitrite formation [Nelson and Hostetler 2003; Flomenbaum et al. 2006; Hunter et al. 2011] (See Table 2 ).
Exposure happens when substances enter the body. There are several ways exposure to nitrates and nitrites can occur: Drinking Water. • The largest source of nitrates in water comes from nitrogen-based fertilizers that get into shallow drinking water wells that are typically in rural areas.
