Assessment of the quality of natural mineral waters from the Vrnjacka Banja area in aspect of the content of macro - and microelements

U okviru ovog rada izvršeno je preliminarno ispitivanje kvaliteta prirodnih mineralnih voda sa teritorije Vrnjačke Banje (U1-U7) određivanjem osnovnih fizičko-hemijskih parametara kao što su: temperatura, pH vrednost, provodljivost, mutnoća, sadržaj hlorida i ukupnih organskih materija, kao i sadržaj amonijaka. Posebna pažnja stavljena je na ispi tivanje sadržaja odabranih makro - i mikroelemenata za čije određivanje je korišćena ana litička tehnika induktivno kuplovana plazma sa optičkom emisionom spektrometrijom, ICP-OES (eng. Inductively coupled plasma - optic emission spectrometry). Koncentracije makroelemenata Ca, Mg i Si u analiziranim uzorcima bile su u granicama dozvoljenih vrednosti, dok je višestruko povišena koncentracija Na detektovana u uzorcima U2, U3, U5 i U7. Povišene koncentracije mikroelemenata zabeležene su u uzorcima: U6 (As); U3-U5 (Se); U1 i U4 (Fe); U1-U4 i U7 (Mn), dok koncentracije ostalih mikroelemenata (S, Ni, Cd) su bile u okviru dozvoljenih vrendosti po Pravilniku o ispravnosti vode za ljudsku upotrebu.In this paper preliminary tests of the quality of natural mineral waters from the Vrnjacka Banja area (U1-U7) were carried out by determining basic physical and chemical parameters such as: temperature, pH value, conductivity, turbidimetry, content of chloride and total organic substances, as well as the content of ammonia. Particular attention was paid to testing the content of selected macro- and microelements by using analytical techniques inductively purchased plasma with optical emission spectrometry, ICP-OES (Inductive Coupled Plasma - Optical Emission Spectrometry). The concentrations of macroelements Ca, Mg, and Si in the analyzed samples were within the limits of the allowed values, while the multiplied concentration of Na was detected in samples U2, U3, U5 and U7. Elevated concentrations of microelements were recorded in the samples: U6 (As); U3-U5 (Se); U1 and U4 (Fe); U1-U4 and U7 (Mn), while the concentrations of other microelements (S, Ni, Cd) were in the allowed values according to the National legislation of water for human use
