Abstract

Vino je popularno i široko konzumirano alkoholno piće i ekonomski važan proizvod. Dnevna konzumacija vina u umjerenoj količini doprinosi znatno potrebama ljudskog organizma za esencijalnim elementima, dok su As, Cd, Pb i Br poznati kao potencijalno toksični. U posljednje vrijeme sve veću popularnost dobiva organski uzgoj hrane, pa tako i vino, time raste i potreba za određivanjem elemenata u organski proizvedenim vinima. Za određivanje koncentracije metala korištene su dvije tehnike, atomska absorpcijska spektrofotometrija i induktivno spregnuta plazma spektrometar masa. Određivane su koncentracije sljedećih metala: Na, Al, Cr, Fe, Ni, Cu, Zn, As, Cd, Sn, Pb i Ag. U vinima se očekuje visoka koncentracija Zn, Fe i Cu, te su ta tri elementa mjerena AAS tehnikom, dok su ostali elementi mjereni ICP-MS tehnikom. Svi analizirani uzorci odgovaraju Pravilniku o vinu (NN/96/96, NN/141/10).

Abstract (english)

Wine is popular and widely consumed alcoholic beverage and economically important product. Daily consumption of wine in moderate amount contributes significantly to the needs of human body with essential elements, while As, Cd, Pb and Br are known to be potentially toxic. Recently, the popularity of growing organic food increased, including wine, thus increasing the need for determining elements in organically produced wines.To determine metal concentrations in wines two techniques were used, atomic absorption spectrometry and inductively coupled plasma mass spectroscopy. The concentrations of the following metals was measured: Na, Al, Cr, Fe, Ni, Cu, Zn, As, Cd, Sn, Pb and Ag. In wine is expected high concentration of Zn, Cu and Fe, and these three elements were measured by AAS technique, while other elements were measured with ICP-MS technique. All analyzed samples correspond to the Regulations on wine (NN / 96/96, NN / 141/10).
