代谢
摄入一定量的硝酸盐和亚硝酸盐是人类氮循环的正常部分。在适当条件下,硝酸盐可以在胃肠道内转化为亚硝酸盐,显著增加硝酸盐的毒性。硝酸盐的主要代谢途径是转化为亚硝酸盐,然后转化为氨。亚硝酸盐、硝酸盐及其代谢物通过尿液排出体外。
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)

毒理性
  • 毒性总结
硝酸盐的毒性是由于它进入体内后转化为亚硝酸盐。亚硝酸盐导致氧合血红蛋白自催化氧化成过氧化氢和高铁血红蛋白。这种高铁血红蛋白水平的升高被称为高铁血红蛋白血症,其特点是组织缺氧,因为高铁血红蛋白不能结合氧气。
Nitrate's toxicity is a result of it's conversion to nitrite once in the body. Nitrite causes the autocatalytic oxidation of oxyhemoglobin to hydrogen peroxide and methemoglobin. This elevation of methemoglobin levels is a condition known as methemoglobinemia, and is characterized by tissue hypoxia, as methemoglobin cannot bind oxygen. (A2450, L1613)

  • 致癌物分类
摄入硝酸盐或亚硝酸盐,在导致内源性亚硝化的条件下,对人类可能是致癌的(2A组)。
Ingested nitrate or nitrite under conditions that result in endogenous nitrosation is probably carcinogenic to humans (Group 2A). (L135)

毒理性
  • 健康影响
硝酸盐和亚硝酸盐中毒会导致高铁血红蛋白血症。亚硝酸盐可能会导致怀孕并发症和发育影响。它们也可能具有致癌性。

  • 症状
硝酸盐和亚硝酸盐中毒导致高铁血红蛋白血症。症状包括发绀、心脏心律不齐和循环衰竭,以及逐渐加重的中枢神经系统(CNS)影响。中枢神经系统的影响可能从轻微的眩晕和嗜睡到昏迷和抽搐不等。
Nitrate and nitrite poisoning causes methemoglobinemia. Symptoms include cyanosis, cardiac dysrhythmias and circulatory failure, and progressive central nervous system (CNS) effects. CNS effects can range from mild dizziness and lethargy to coma and convulsions. (L1137)
