摘　　要： 建立了一种电热解-原子吸收光谱法快速测定食用菌中汞的方法,该方法汞的检出限为0.079ng(3σ),加标回收率为91.5%～104.6%。该方法与原子荧光光谱法对照,不需要进行样品前处理且结果无显著性差异,为食用菌产品汞的质量控制提供了一种快速、准确的分析方法。对分析中可能出现的共存元素干扰以及样品取样量等因素进行了讨论,并对样品的检测结果进行了安全性评价和原因分析以及提出了在食用菌栽培中有效控制汞含量水平的几个因素。 A rapid determination method of mercury in edible fungi by electropyrolysis atomic absorption spectrometry was established.The detection limit of mercury of the method was 0.079ng （ 3σ） . The recovery of standard addition was from 91.5% to 104.6%.Compared with atomic fluorescence spectrometry（ AFS） ,the samples need not be prepared and the results had no significant difference. A fast and accurate analytical method of mercury for the edible fungi was applied to control its quality. In the results,not only were the interferences of coexisting elements in edible fungi and sample weight discussed,but also were the safeties of the detection results evaluated and cause analyzed,and several factors to control the mercury level in edible fungi cultivating were given.
