ABSTRACT. The main sources of essential trace element selenium (Se) to humans are plants, animals and water. Though Se concentration in water is low, the values are considered to be good markers of the environmental Se status. Se content in groundwater of 22 springs, wells and bottled water samples produced at the territory of the Crimea has been determined. Uneven distribution of Se at the territory of the Crimea was reflected in a broad concentrations range of the element from 0.082 to 7.85 µg/L with the highest values typical for Simferopol well and 2 samples of bottled water: ‘Crimean paradise’ and ‘Kula’ (1.25–1.38 µg/L). Two liters of water from Simferopol well provide up to 24% of the daily adequate Se consumption level. Chemical analysis of groundwater quality recorded high ecological risks connected with increased nitrates levels in more than 30% of samples investigated (up to 194 mg/L) and high mineralization (up to 1540 mg/L). Chemical analysis of fresh water demonstrated unsuitability for consumption of ‘Saki’ bottled water, characterized by significant MPC excess for nitrates (4.3 MPC), chlorides (1.4 MPC), fluorine (1.19 MPC) and mineralization (1.54 MPC). The work indicates the necessity of wide groundwater quality monitoring for the whole Crimean peninsula.
