Lithium in drinking water, altitude, and suicide rates in rural areas of Argentinean Andes.

摘要: The Lithium Triangle in the Andean plateau involves high altitude (>3,000 m asl) hydrological systems having lithium graded waters. This research was carried-out rural areas of north westernmost Argentinean Andes and aimed: 1) to determine concentrations drinking waters; 2) calculate suicide mortality rates based on available official data (2003-2013); 3) analyze bivariate differences between water, mean mortality, sampling sites, water sources; 4) correlations altitude; 5) test predictive models for when considering predictors altitude, sources. determinations waters were performed by Microwave Plasma-Atomic Emission Spectrometer. Nonparametric tests applied correlations. Generalized linear (GLM) used fitting suicide. Drinking contained up 2.98 mg L-1 lithium. Mean (per 100,000 inhabitants) high, ranging from 19.12 (± 19.83) 30.22 16.70). but not positively correlated with analyzing (Li: rho = 0.76, p-value < 0.001). However, GLM calculated, a significant interaction effect found (p-value would act some way restraining rates.
