BACKGROUND
In pharmacological doses, lithium successfully treats bipolar disorder and it can reduce violent crimes committed by individuals with this disorder.
AIMS
To investigate whether naturally occurring lithium in drinking water lowers rates of violent crime in the general population.
METHOD
We examined lithium levels in the drinking water of the 274 municipalities of Kyushu Island in Japan and compared these with the crime rates in each municipality.
RESULTS
We found that lithium levels were significantly and inversely associated with crime rates in 2009.
CONCLUSIONS
Our findings suggest that even very low levels of lithium in drinking water may play a role in reducing crime rates in the general population.
背景
在药理学剂量下，锂能成功治疗双相情感障碍，并且可以减少患有这种疾病的个体实施的暴力犯罪。
目的
调查饮用水中天然存在的锂是否会降低普通人群的暴力犯罪率。
方法
我们检测了日本九州岛274个市的饮用水中的锂含量，并将其与各市的犯罪率进行比较。
结果
我们发现2009年锂含量与犯罪率显著负相关。
结论
我们的研究结果表明，即使饮用水中锂含量极低，也可能在降低普通人群犯罪率方面发挥作用。
