Opis:: Background. Heavy metals are at present classified among the most important and dangerous water pollutants. Since over 15 years parasites have been used as a bioindicators of water pollution, e.g. using their ability to accumulate heavy metals. Concentration of four elements (Zn, Cd, Ni, Cu) in selected organs of the perch (Perca fluviatilis) and in the tissues of its parasite, plerocercoid of the tapeworm Triaenophorus nodulosus, was analysed. Material and methods. The fish were subject to full helminthological section, resulting in 66 tapeworm larvae isolated from cysts, located in the liver. Plerocecroids, gills, liver and intestine with duodenum were removed and frozen. Content of heavy metals was determined with atomic absorption spectroscopy method. Results. The distribution of the content of Ni, Cd and Zn was similar. In all cases, among all the examined fish organs, the highest mean concentration of the metals was found in the liver, followed by the intestine; it was the lowest in the gills. The mean concentration of the metals in the tapeworm tissues was from 6 to 74 x higher than in the gills, 5−37 x higher than in the intestine and 2.5−28 x higher than in the liver. The concentration of Cu was also the highest in the tapeworm tissues, but its concentration in the fish intestine and liver was nearly the same; it was the lowest in the gills.
