摘　　要：目的：对使用氢化物发生-原子荧光光谱法测定全血中铅的方法进行系统的研究,建立一个灵敏、准确、高效、廉价的血铅测定的方法.方法：氢化物发生-原子荧光光谱法.结果：取1.0 ml血样消解,定容至10.0 ml上机测定,则方法的检出限为1.6 μg/L,回收率95%～106%.结论：氢化物发生-原子荧光光谱法测定全血中铅的方法,灵敏度与检出限均能达到血铅测定的要求,适用于我国绝大部分医疗机构开展铅防治工作.Objective：To process a systematic research on determination of lead（Pb） in whole blood by hydride generation atomic fluorescence spectrometry. To establish an sensitive, accurate, efficient, economic method to determine the lead in blood. Methods：Hydride generation atomic fluorescence spectrometry was employed. Results：Obtaining 1.0 ml blood sample, and pour to a 10. 0 ml container. Testing with hydride generation atomic fluorescence spectrometry, the minimum detectability was 1.6μg/L. The yield percentage was between 95% to 106%. Conclusion：The sensitivity and the minimum detectability of this method fulfill the requirement of blood lead determination. It is applicable to most medical institutions to launch lead prevention.
