A simple method for cadmium and lead determination in foods by beam injection flame furnace atomic absorption spectrometry (BIFF-AAS) was proposed. Food slurries were prepared by transferring an exact amount of cryogenic-ground homogenized material (50-100mg) to centrifuge tubes, followed by addition of 5ml (up to 2.8moll - 1 ) nitric acid solution and sonication in an ultrasonic bath during 5-10min. Thereafter, slurries were diluted with water to 10ml, centrifuged during 5min at 5400rpm and 400μl aliquot of the supernatant was analyzed by BIFF-AAS. The detection limits based on peak height measurements were 0.03μgg - 1 Cd and 1.6μgg - 1 Pb for 2% (m/v) slurry (200mg/10ml). For method validation, the certified reference materials Pig Kidney (BCR 186) and Rice Flour (NIES 10) were used. Quantitative cadmium and lead recoveries were obtained and no statistical differences were found at 95% level by applying the t-test.
