【 摘 要 】

Comparative analysis between bottled and tap waters as well as its comparisonwith current Serbian regulations, European Union Directives and World HealthOrganization standard are shown in this paper. Thirteen bottled waters andfourteen tap waters from the territory of Serbia were analyzed in theFederal Institute for Geosciences and Natural Resources (BGR) laboratory inBerlin, for the purpose of the “Geochemistry of European Bottled Water“project conducted by EuroGeo Survey Geochemistry (EGS). Macrocomponents(main cations and anions) of ground waters usually reflect onlithogeochemistry of the aquifer, while microcomponents indicate thecirculation of ground water through the different lithological environment.Analyzed bottled waters could be classified as those with low mineralcontent (M<500 mg/L) if HCO3 anion and Ca and Mg cations were the prevailingones, or mineral (M>500 mg/L) with prevailing HCO3 anion and Na cation.Waters with low mineral content were mainly from limestone and dolomite,while mineral waters mainly originated from magmatic and metamorphic rocks.Higher content of Cs, Li, Ge, Rb and F in bottled waters indicates theimportance of the magmatic intrusions influence on their chemicalcomposition. In some waters higher content of B, I, NH4, as well as of Tland W has been observed which can be attributed to water’s circulationthrough different lithological complexes. Tap water was mostly obtained fromgroundwater (from Neogen and alluvial aquifers and karst springs) with restbeing those of rivers and surface accumulations. Tap waters from CentralSerbia were with low mineral content, with prevailing HCO3 anion and Ca andMg cations, while waters from Vojvodina, the northern province of Serbia,were with higher mineralization, HCO3-Na. Chemical analyses of the sampledtap waters showed good quality, with exception of waters from the cities ofSenta and Zrenjanin in Vojvodina. High values of B (1170 and 895 g/L), As(20.9 and 71.9 g/l), Na (208 and 275 mg/L), as well as EC (715 and 928 S/cm)have been registered in these waters.
