Objective ：To establish microwave digestion -graphite furnace atomic absorption spectrometry for the determination of lead in children＇s hair. Methods：The samples were digested with microwave oven and determined by graphite furnace atomic absorption spectrometry. Results： The correlation coefficient of the metod was 0. 9996 with RSDs of 1.15% - 2.16% and average recoveries of 94.4% - 102%. Conclusion： The method is accurate, precisive and sensitive, it is suitable for the determination of lead in hair.
