汞化合物具有脂溶性 ,易蓄积于红细胞和中枢神经系统 ,因此具有很高的毒性。通常测定总汞的方法是冷原子吸收光谱法。因为只有二价无机汞才能被冷原子吸收法定量地检测 ,所以需要进行高温消化来破坏样品中的有机汞化合物。这一过程有被试剂污染的危险并且因为汞具有高挥发性而
Mercury compounds are lipid-soluble, easy to accumulate in the red blood cells and the central nervous system, and therefore has high toxicity. The general method for determining total mercury is cold atomic absorption spectrometry. Because only divalent inorganic mercury can be quantitatively detected by cold atomic absorption spectroscopy, high temperature digestion is required to destroy the organic mercury compounds in the sample. This process is at risk of being contaminated with reagents and because of the high volatility of mercury
