Reactivity Profile
NITRITES, INORGANIC, N.O.S. are oxidizing agents. React with acids to form toxic nitrogen dioxide gas. A violent explosion occurs if an ammonium salt is melted with a nitrite salt [Von Schwartz 1918. p 299]. A mixture with potassium cyanide may cause an explosion [Pieters 1957. p. 30].

Metabolism/Metabolites
Intake of some amount of nitrates and nitrites is a normal part of the nitrogen cycle in humans. In vivo conversion of nitrates to nitrites can occur in the gastrointestional tract under the right conditions, significantly enhancing nitrates' toxic potency. The major metabolic pathway for nitrate is conversion to nitrite, and then to ammonia. Nitrites, nitrates, and their metabolites are excreted in the urine. (L1137)
用途と製造
UsesNitrates and nitrites are naturally produced and may also be found in pesticides. Exposure usually occurs from contact with contaminated soil, food water. Nitrates may also be found in certain drugs. (L1137)
