Abstract: A method applying a gold fibre microelectrode is proposed for differential pulse anodic stripping voltammetry determination of traces of mercury in food products - fruit juices and beer. The method was tested using synthetic samples containing Hg at the trace level well below the state regulation limiting mass fraction value 10 x 10^-9 for mercury content in food products. It was applied to Hg analysis in some real samples of fruit juices Fruiko and beer distributed to market.
