Abstract: 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.
