CADMIUM, COPPER, LEAD AND ZINC CONCENTRATIONS IN LOW QUALITY WINES AND ALCOHOL CONTAINING DRINKS FROM ITALY, BULGARIA AND POLAND

Abstract

We studied Cu, Cd, Pb and Zn concentrations in low quality wines produced in Bulgaria and Italy and in alcohol containing multi-fruit drinks produced in Poland. All the metals were present in tested products. Cadmium was not detected in Italian and Polish products. In one of the Bulgarian wines cadmium was detected in concentration of 0.004 mg•l-1. Italian wines were not contaminated with Pb. Its concentration was the highest in Polish drinks (0.88±0.52 mg•l-1). The largest and statistically significant differences occurred between Cu and Zn contents. Both metals had the highest concetrations in Italian wines (Cu - 0.13±0.05 mg•l-1; Zn - 0.83±0.56 mg•l-1), and the lowest in Polish products (Cu - 0.04±0.001 mg•l-1; Zn -0.18±0.16 mg•l-1).
