The purpose of the present study was to evaluate the association between lithium levels in the public water supply and incidences of homicide in Greece. A total of 149 samples of drinking water were collected from 34 out of 52 prefectures, and data for homicides were taken from National Statistic Service of Greece (Hellenic Statistical Authority - EL.STAT). The average lithium level was 11.10 μg/l (SD = 21.16). The results indicate that there is a tendency for lower mean number of homicides in the prefectures with high levels of lithium in drinking water (R(2) = 0.054, β = -0.38, p = .004). Considering the results of our previous study, which showed an inverse association between the lithium levels in drinking water and the incidence of suicide, homicide, rape, and drug abuse, we suggest that natural lithium level intake may influence impulsiveness, a factor that mediate to the manifestation of both suicidality and aggressiveness.
本研究的目的是评估希腊公共供水系统中的锂含量与杀人案件发生率之间的关联。从52个行政区中的34个行政区共采集了149份饮用水样本，杀人案件数据取自希腊国家统计局（希腊统计局 - EL.STAT）。锂的平均含量为11.10微克/升（标准差 = 21.16）。结果表明，饮用水中锂含量高的行政区杀人案件的平均数量有减少的趋势（R(2)=0.054，β=-0.38，p = 0.004）。考虑到我们之前研究的结果，该研究表明饮用水中的锂含量与自杀、杀人、强奸和药物滥用的发生率呈负相关，我们认为天然锂摄入量可能会影响冲动性，而冲动性是自杀和攻击性表现的一个介导因素。
