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)
