Heavy metals represent an important health risk to people living in historically contaminated areas with these substances, especially due to their bioaccumulation in soils, through the transfer to vegetables affecting the health of consumers. The aim of this study was to determine the concentrations of heavy metals (Pb, Cd, Cu and Zn) in vegetables grown in two nonferrous metallurgical industrial areas in Romania: Copşa Mică and Zlatna. Samples of potato, carrot and yellow onion harvested in these regions were analysed through atomic absorption spectrophotometric techniques and the results revealed elevated Pb and Cd concentrations in carrots and yellow onion grown in Copşa Mică area, while the concentrations of Pb and Cd in vegetables harvested in Zlatna area exceed the maximum limits only in carrots. Concentrations of Cu and Zn in vegetables analysed were below the maximum permissible limits, both in Zlatna and Copşa Mică area.
