Trace amounts of lithium in drinking water may reduce a population's suicide rates, according to an analysis conducted by researchers from the universities of Oita and Hiroshima, Japan, and published in the British Journal of Psychiatry.

But mental health advocates warned against adopting plans to add the element to public drinking water supplies, as in controversial water fluoridation programs.

Lithium is a naturally occurring element that has long been used for the treatment of bipolar disorder. Unlike conventional antidepressants, lithium stabilizes moods at both extremes of the spectrum -- depression and mania. Research conducted on data collected in the 1980s has previously suggested that communities with higher concentrations of lithium in their tap water might have lower suicide rates than communities with lower levels.

To follow up on this research, scientists measured the levels of lithium in the drinking water of 18 different municipalities in the Japanese prefecture of Oita, finding concentrations ranging from 0.7 to 59 micrograms per liter. They then compared these numbers with the suicide rates in each community.

The researchers found that suicide rates were lowest in municipalities with the highest concentrations of lithium in the water.

"Our study suggests that very low levels of lithium in drinking water can lower the risk of suicide," the researchers wrote. "Very low levels may possess an antisuicidal effect."

Sophie Corlett of the mental health nonprofit Mind greeted the findings with caution.

"We already know that lithium can act as a powerful mood stabilizer for people with bipolar disorder, and treating people with lithium is also associated with lower suicide rates," she said. "However, lithium also has significant and an unpleasant side effects in higher doses, and can be toxic. Any suggestion that it should be added, even in tiny amounts, to drinking water should be treated with caution and researched very thoroughly."

There is a very small difference between a clinical and a toxic dose of lithium.

饮用水中微量锂的水可能会减少人口的xx率，根据从大分和日本广岛大学研究人员进行分析，并在英国精神病学杂志发表。

但是，心理健康倡导者警告采取计划中添加元素公共饮用水供水，在水中加氟的争议程序。

锂是一种自然发生的元素，一直用于xx双相障碍的使用。与传统的抗抑郁药，锂稳定在光谱两个极端的情绪 - 抑郁症和躁狂症。研究进行了20世纪80年代以前收集的数据表明，具有较高的浓度，锂社区的自来水可能较低水平比社区的降低xx率。

为了进一步落实了这项研究，科学家测量了饮用水的锂水平在日本大分县的18个不同的城市水，发现浓度为0.7至每公升59微克不等。然后，他们与每个社区的xx率这些数字。

研究人员发现，xx率{zd1}的市与{zg}的锂在水中的浓度。

“我们的研究表明，饮用水中锂非常低的水平水可降低xx的风险，”研究人员写道。 “非常低的水平可能拥有一个antisuicidal效果。”

索菲的非营利性心理健康心灵力行谨慎欢迎的结果。

“我们已经知道，锂可以作为与躁郁症的强大情绪稳定，以及对待锂的人也xx率较低有关，”她说。 “不过，也有重要的锂，并在高剂量的令人不快的副作用，而且可能是有毒的。任何认为应增加，建议即使在微量，饮用水应谨慎对待和研究得很周全。”
