A flow injection hydride generation atomic (FI-HG-AAS) method was developed for determination of arsenic in certified reference materials after open wet digestion of samples. Steps of the method were optimized and analytical as well as statistical parameters of the method were determined (Detection limit 1 μg/kg-1, Quantification limit 3 μg/kg-1). Accuracy of the method was evaluated using GBW10043 (Rice), GBW100052 (Green tea), T0770 (soya flour), NCS-ZC 73013 (Spinach), NCS-ZC 73015 (Milk powder) reference materials.
