A method of graphite furnace atomic absorption spectrometry (GFAAS) with a direct atomization technique has been developed for the determination of trace amounts of (\mathrm{Cd}) and (\mathrm{Pb}) in human teeth and artificial teeth. The samples were ground to a particle size of less than (10 \mu \mathrm{m}) and mixed with the same amount of graphite powder. One-half to (2 \mathrm{mg}) of mixed sample was weighed in a tared graphite cup and atomized in a cup-type graphite furnace according to the heating program that was established. Absorbances were determined by integration of the spectral lines in the absorbance vs time spectrum. Calibration was affected using aqueous standard solutions. The results for six human tooth samples and two artificial tooth samples were in good agreement with the values obtained by GFAAS for dissolved samples. The relative standard deviations were (3.1-12 %) ( (n) (=10)) for Cd ( (19-95 \mathrm{ng} \mathrm{g}^{-3}) ) and (0.9-8.1 %(n=10)) for (\mathrm{Pb}\left(1.43-6.32 \mu \mathrm{g} \mathrm{g}^{-3}\right)). The determination limits corresponding to twice the standard deviation ( (\sigma, n=10) ) for blank measurements were (13 \mathrm{pg}) for (\mathrm{Cd}) and (53 \mathrm{pg}) for Pb. 1995 Academic Press, Inc.
