Infants can develop acquired methemoglobinemia due to intake of well water high in nitrate concentrations. Although methemoglobinemia usually presents with more severe symptoms, this diagnosis should be considered in an infant with intermittent cyanosis in the absence of underlying heart or lung disease. Well water should be avoided in infancy unless properly tested.
婴儿因摄入硝酸盐浓度高的井水可发生获得性高铁血红蛋白血症。尽管高铁血红蛋白血症通常表现出更严重的症状，但对于无潜在心肺疾病却出现间歇性发绀的婴儿，应考虑这一诊断。除非经过适当检测，婴儿期应避免饮用井水。
