The mercury concentration was quantified in frozen and canned fish found in the market of the Republic of Srpska, Bosnia and Herzegovina. Using the method of amalgamation by atomic absorption spectrophotometry with a direct mercury analyzer (DMA-80), significant differences in mercury concentrations among the analyzed fish were found. Frozen pangasius and canned tuna had the highest mercury concentration (59.1 μg/kg and 54.1 μg/kg, respectively). Also, fish from Vietnam had the highest level of total mercury in comparison to fish from other countries. Determined levels of mercury in our samples were below the limit set by the European and Bosnian and Herzegovinian legislation (500 μg/kg wet weight). We have concluded that consumption of commercial fish in the market of the Republic of Srpska does not present any health risk for the average consumer. Nevertheless, a surveillance system of mercury content in fishery products, especially in certain species that concentrate mercury, is crucial for public health protection.
