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 eleva ted pressure and temperature in a digestion device is described. The m ethod was tested on synthetic samples spiked with Hg(ClO4)2. Sufficien t decomposition of the organic matrix was reached during the sample pr etreatment and no significant loss of mercury was observed.
