LEVELS OF LEAD AND CADMIUM ON WHEAT FLOURS ON THE ROMANIAN MARKET: AN ATOMIC ABSORPTION SPECTROMETRY ANALYSIS
Cereal industry and its derived products, especially wheat flour, have a big economic and social importance in Romania and worldwide. Therefore, as wheat flour is the main ingredient for obtaining bread, the most consumed product among Romanian people, its safety is of real wide interest.
The present work aims to determine the concentrations of Lead and Cadmium in 33 different wheat flour samples, available on the Romanian market. Analysis was performed by atomic absorption spectrometry with graphite furnace (GF-AAS), after dry digestion. Lead content ranged between 0.002 and 0.137 mg/kg while cadmium content ranged between 0.0002 and 0.024 mg/kg. All samples were within the accepted limits, imposed by the legislation in force.
