The concentration of mercury in selected organs (muscles, liver and gills) of five fish species was measured by flameless cold vapor atomic absorption spectrometry (CV AAS).Differences in the total mercury content were found both between species and organs. The concentration of mercury turned out to be higher in muscles of freshwater fish than in other organs The muscle tissue of freshwater fish contained a higher concentration of mercury (0.135 mg/kg) than that of marine fish (0.052 mg/kg). In turn, the content of mercury (0.033 mg/kg) in gills of marine fish was higher than in the freshwater fish (0.019 mg/kg),whereas the content of mercury in liver of freshwater fish was close to that of the marine fish (0.051 mg/kg and 0.053 mg/kg, respectively)
