摘要：

Gold fibre microelectrode was applied for mercury traces determination by differential pulse anodic stripping voltammetry in mushrooms. The food sample decomposition procedure with concentrated HNO3 under elevated pressure and temperature in a digestion device is described. The method was tested on synthetic samples spiked with Hg(ClO4)2. Sufficient decomposition of the organic matrix was reached during the sample pretreatment and no significant loss of mercury was observed.
