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。在适当的条件下,硝酸盐可以在胃肠系统中转化为亚硝酸盐,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。亚硝酸盐会导致氧合血红蛋白的自动催化氧化,生成过氧化氢和高铁血红蛋白。高铁血红蛋白水平的升高是一种称为高铁血红蛋白血症的状况,其特点是组织缺氧,因为高铁血红蛋白无法结合氧气。
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)

  • 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。
Nitrate and nitrite poisoning causes methemoglobinemia. Nitrites may cause pregnancy complications and developmental effects. They may also be carcinogenic. (L1137)

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头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)

    摘要:
    A conductance study of the interaction between Rb+ and Cs+ ions and 18-crown-6 (18C6), dicyclohexyl-18-crown-6 (DC18C6), dibenzo-18-crown-6 (DB 18C6), dibenzo-24-crown-8 (DB24C8), and dibenzo-30-crown-10 (DB30C10) in acetonitrile solution has been carried out at various temperatures. The formation constants of the resulting 1:1 complexes were determined from the molar conductance-mole ratio data and found to vary in the orderDC18C6 > 18C6 > DB30C10 > DB18C6 > DB24C8for Rb+ ion andDC18C6 > 18C6 > DB30C10 similar to DB24C8 > DB18C6for Cs+ ion. The enthalpy and entropy of complexation were determined from the temperature dependence of the formation constants. The complexes with the 18-crowns are both enthalpy and entropy stabilized while, in the case of large crown ethers, the corresponding complexes are enthalpy stabilized but entropy destabilized.

    Ba-substituted CsTiSi2O6.5 were obtained from drop solution calorimetry in a molten lead borate solvent at 702°C. The enthalpies of formation, from constituent oxides, are exothermic and it decreases with increasing Ba content.
