IDENTIFICATION AND USE: Sodium azide is a colorless to white crystalline solid, forming hydrazoic acid in water. It is used in organic synthesis, and in the preparation of hydrazoic acid, lead azide, and pure sodium. Other uses include the differential selection of bacteria, in automatic blood counters, and as a preservative for laboratory reagents. It is also a propellant for inflating automotive safety bags. Agricultural uses including nematocide, herbicide, and fruit rot control. HUMAN STUDIES: Potential symptoms of overexposure include irritation of eyes and skin, nausea, vomiting, restlessness, diarrhea, headache, dizziness, weakness, blurred vision, dyspnea, hypotension, tachycardia, bradycardia, tachypnea, hypothermia, acidosis, convulsions, and kidney changes. Cases of fatal sodium azide poisoning induced by suicidal ingestion have been reported. Death occurs rapidly when significant doses are absorbed, either due to the direct effect of sodium azide or an indirect effect due to nitric oxide, cyanide ions or hydrazoic acid production from sodium azide. The minimal hypotensive dose in humans lies between 0.2 and 0.4 ug/kg. Neuropsychological and psychological tests, a questionnaire, and hematological and cardiac measurements were gathered from 41 exposed workers and 42 unexposed workers in a chemical production plant yearly for 3 years. The exposed workers presented significantly more acute symptoms of exposure (headache, vertigo, nausea, fatigue, cardiac palpitations, irritated or red eyes) than did the unexposed workers. However, only one chronic symptom was repeatedly and more significantly reported, namely trembling of the hands. Azide is one of the few known potent mutagens that does not increase sister-chromatid exchanges SCEs and/or break chromosomes. ANIMAL STUDIES: Sodium azide inhibits respiration of bovine cornea, presumably by poisoning cytochrome oxidase. Repeated intraperitoneal injections in rats (5 to 10 mg/kg every 15 to 30 min for 3 to 6 hr) resulted in severe intoxication; some survivors showed injury and demyelination of nerve fibers in the central nervous system and testicular damage, but no lesions of liver or kidney. Intramuscular injection of 8 to 10 mg/kg in monkeys produced convulsions and apnea and resulted in the deaths of many of these animals. Among those who survived, ataxia developed secondary to the lesions in the cerebellar cortex; repeated administration caused necrosis and demyelination of the optic nerves and destruction of the caudate nucleus and putamen of the lenticular nucleus. In a chronic rat study in which the maximum tolerated dose and half that level were given in the diet or by gastric intubation twice weekly for 18 months, sodium azide was determined to be noncarcinogenic. Sterility has been produced in male mice given sodium azide. Sodium azide effectively reverts S. typhimurium strain TA1530, indicating that it is a base substitution mutagen. It is ineffective on strains which are frameshift mutants. It is highly mutagenic in barley, rice, peas, yeast and Chinese hamster V79 cells. However, azide apparently does not produce chromosome breaks in barley or Vicia. ECOTOXICITY STUDIES: Sodium azide is a potent mutagen of salmon sperm DNA in an acidic environment. Heritable translocation noted in insects after oral mutation dose 100 mg/L. Sodium azide induced a high frequency of mutations in barley seeds. Sodium azide does not induce somatic crossing over and chromosome breaks in soybeans.
... Sodium azide appeared in rat plasma 5 minutes after a single oral dose at 40 mg/kg and ... by 24 hours, no azide could be detected in either blood or peripheral tissues. A small fraction (7.9 ug) of the administered dose was eliminated in rat urine, but no azide was detected in expired air or feces.
