Abstract: The graphite furnace atomic absorption method with praphite probe has been used satisfactorily in determination of trace lead in hair. A linear relationship between the concentration of lead and peak area of absorbance was found, when the former is 0~250.μg/L. The method has a recovery of 98%~102%.

Key words: graphite furnace atomic absorption spectrometry, graphite probe, trace lead, human hair
