[Studies on lithium in the environment and its effects on the central nervous system]

This paper introduces the distribution of global lithium resources and absorption, distribution, metabolism and excretion of lithium in the human body, discussing the positive effect of lithium in the environment on the nervous system and its neuroprotective mechanism. The tiny amounts of lithium that enter the body through the food chain have been linked to beneficial health effects, such as improved cognition and reduced depression and violence. However, the safe dose range of lithium is narrow, and the health effects of drinking high concentrations of lithium water in high-lithium areas are unclear. It is necessary to study the health effects and mechanisms of different doses of lithium, especially high concentrations of lithium in the environment.
