A method is presented for the rapid determination of total mercury in blood. The reagent used is alkaline sodium borohydride, and no digestion of the sample is needed. The detection limit and sensitivity are 1.15 and 1.59 ng of Hg, respectively. The method gives reproducible results (the CV ranged from 5.3 to 6.7% for low and high mercury blood samples, respectively), comparable to those obtained by the digestion method. The mean analytical recoveries of added mercuric chloride and methylmercuric chloride were 106.65 and 99.02%, respectively. Other advantages of the method are freedom from contamination encountered with digestion methods and elimination of matrix effects.
本文介绍了一种快速测定血液中总汞的方法。所用试剂为碱性硼氢化钠，无需对样品进行消解。检测限和灵敏度分别为1.15 ng汞和1.59 ng汞。该方法结果具有可重复性（低汞和高汞血样的CV分别为5.3%至6.7%），与消解方法所得结果相当。添加的氯化汞和甲基氯化汞的平均分析回收率分别为106.65%和99.02%。该方法的其他优点包括无消解方法所遇到的污染以及消除了基质效应。
