The work deals with the determination of heavy metals (mercury, cadmium and lead) in carp tissues by the use of atomic absorption spectrometry. The theoretical part is focused on the heavy metals and their forms in fishes and in the environment. The anatomy of fishes and the composition of the fish meat are also discussed. The practical part summarized the results of concentrations of studied heavy metals in the carp's tail muscles and in their liver. Carps were fished in two locations - The Pilský reservoir and Domanínský lake situated in Žďár nad Sázavou district. For mercury determination was used one-purpose atomic absorption spectrometer AMA 254. The amounts of cadmium and lead were measured by the electrotermal atomic absorption spectrometry by use of spectrometr ContrAA 700. The obtained results were discussed and evaluated. Obtained concentrations of mercury and lead did not exceed the regulation limits, only concentration of cadmium in liver exceeded these limits in all samples.
