Abstract
The aim of this study was to determine lithium concentration in potable water, surface water, ground, and mineral water on the territory of the Republic of Macedonia. Water samples were collected from water bodies such as multiple public water supply systems located in 13 cities, wells boreholes located in 12 areas, lakes and rivers located in three different areas. Determination of lithium concentration in potable water, surface water was performed by the technique of inductively coupled plasma-mass spectrometry, while in ground water samples from wells boreholes and mineral waters with the technique of ion chromatography. The research shows that lithium concentration in potable water ranging from 0.1 to 5.2 μg/L; in surface water from 0.5 to 15.0 μg/L; ground water from wells boreholes from 16.0 to 49.1 μg/L and mineral water from 125.2 to 484.9 μg/L. Obtained values are in accordance with the relevant international values for the lithium content in water.

Of the importance that lithium has on the functioning of the human body, scientists[2] found that recommended daily dietary intake of lithium for adults with an average body mass of 70 kg is 1 mg/day, which is equivalent to 14.3 μg/kg body mass
The samples of potable water from public water supply systems were investigated, as well as surface water, ground water from wells boreholes and mineral water taken from the territory of the Republic of Macedonia [Figure 1]
Summary
The aim of this study was to determine lithium concentration in potable water, surface water, ground, and mineral water on the territory of the Republic of Macedonia. Determination of lithium concentration in potable water, surface water was performed by the technique of inductively coupled plasmamass spectrometry, while in ground water samples from wells boreholes and mineral waters with the technique of ion chromatography. The research shows that lithium concentration in potable water ranging from 0.1 to 5.2 μg/L; in surface water from 0.5 to 15.0 μg/L; ground water from wells boreholes from 16.0 to 49.1 μg/L and mineral water from 125.2 to 484.9 μg/L. Surveys conducted by Weiner[1] for the lithium intake in our organism, show that the main part of the lithium intake is inserted through cereals and vegetables 430 and 2900 μg/day, while through food from animal origin in our body are inserted insignificant concentration (2.5 μg/day). The concentration of lithium in the internal organs reaches a maximum concentration in the first trimester of gestation, with a gradual decline to the end of the pregnancy.[5]
