摘　　要：中子活化分析法测汞具有灵敏、准确、无试剂空白、能作多元素同时分析的优点。但与某些非核分析方法比较，分析成本比较高，需考虑汞的辐射稳定性而使方法复杂化，对某些低汞含量生物样品的分析必需作某些干扰元素的分离，测试步骤复杂，操作费力．耗时长。原子荧光光度法作为一种非核分析法测汞，同样具有灵敏、准确和重现性好的优点，而且方法简单、快速，分析成本低，结合样品分离和测定条件的选择，可同时作发汞和有机汞的测定。An elaborate comparison is made between two methods, i.e. NAA (neutron activation analysis) and AFS (atomic fluorescence analysis), for determining mercury in human hair on the basis of the authors' experience. It is emphasised that in spite of advantages of NAA such as high sensitivity, accuracy and the multielementanalysis feasibility, AFS method seems more suitable for the determination of both organic and inorganic mercury in human hair samples under some conditions due to itS simplicity, rapidity and low cost.
