The purpose of this study was to investigate the level of lead, cadmium, and chromium in red and wine samples produced in different parts of the world. All wine samples purchased from local stores and treated before analysis. The thermal behavior of Cd, Cr and Pb during pyrolysis and atomization stages investigated with and without matrix modifier. The concentrations of cadmium, chromium and lead ranged from 300 to 970 µg/l, 16 to 170 µg/l and 12.0 – 35.0 µg/L, respectively. The concentrations of Cd and Cr were well below the maximum permissible levels set by the International Organization of Vine and Wine. However, the lead content of a couple of wine exceeded the maximum permissible level set by the International Association of Vine and Wine, 10 ppb. The precision was better than 7% for 95% of the samples.<br/>
