Abstract: Comparisons are made of mercury concentrations in muscle tissue of three fish species caught in two lake’s points ( Bourgas Lake and Mandra Lake ) with two marine fish species caught from the south part of Bulgaria Black Sea (Nesebbar). The freshwater species are gibel carp, roach and perch. The seawater fish species are sprat and Mediterranean horse mackerel. The total mercury determination was performed by Milestone Direct Mercury Analyzer DMA-80.The results were expressed as mg/kg w.w. The mean concentration of gibel carp was 0.0162 mg/kg w.w; of roach varies between 0.0273-0.0233 mg/kg w.w (depending on the location); of perch was 0.0273 mg/kg w.w. On the contrary, the mean concentrations of two sea fish species were higher: sprat was 0.12 mg/kg w.w and Mediterranean horse mackerel was 0.16 mg/kg w.w. Concentrations of mercury were within the limits set from various health organization and are at acceptable levels for human consumption.
