Heavy metal content in different types of smoked meat in Serbia.

Concentrations of Fe, Cu, Ni, Cr, Pb, Mn, Zn and Cd in pork, beef, turkey and chicken samples were determined using inductively coupled plasma-optical emission spectrometry (ICP-OES). The mean concentration ranges in milligrams per 100 g of the studied metals in all samples were 0.6924-1.2154 for Fe, 0.6492-0.9831 for Cu, 0.0012-0.0027 for Pb, 0.041-0.0510 for Ni, 0.1186-0.1481 for Mn, 0.7257-5.2726 for Zn and 0.0042-0.0050 for Cd. The levels of analysed elements were in accordance with European standards for all metals except for manganese in all samples and for nickel in a certain number of samples. Zn level in beef was significantly higher compared to other samples, and Pb and Cd were found in concentrations well below the recommended daily intake.
