W kilku gatunkach win oraz napojów alkoholowych (koktajle) oznaczono zawartość kadmu, ołowiu, chromu, cynku, manganu, miedzi, niklu i żelaza. Pierwiastki oznaczono bezpośrednio z mineralizatu, jak też po ekstrakcji ich kompleksów do fazy organicznej metodą płomieniową atomowej spektrometrii absorpcyjnej.

Cadmium, lead, chromium, zinc, manganese, copper, nickel and iron levels in eight wine and coctail grades were determined by flame atomic absorption spectrometry. Chromium, zinc, manganese, copper, and iron were determined by flame atomic absorption spectrometry directly form the mineralizates. Lead, cadmium and nickel were assayed using ammonium pyrrolidine dithiocarbonate (APDC) as complexing agent and 4-methyl-2-pentanone as organic extraction solvent. Average lead, cadmium and nickel level ranges were: 11,0-51,8 µg/l; 0,4-1,9 µg/l; and 19,4-73,2 µg/l, respectively. Copper and chromium levels in the wines and coctails were form 0,08 to 0,71 mg/l and from 0,010 to 0,060 mg/l, respectively. The highest concentrations were found for iron between 3,36 and 7,30 mg/l. Zinc and manganese levels were in the range 0,20 - 0,56 mg/l and 0,36 - 1,21 mg/l, respectively. Our data were compared with data form other sources and did not exceed the maximum admissible concentration values specified in revelent Polish standards.
