Abstract: [cze] [eng]
U dvou parazito-hostitelských systémů (tesemnice vs. ryba) byly analyzovány koncentrace těžkých kovů. U systému Ligula intestinalis vs. cejn velký (Abramis brama), cejnek malý (Blicca bjoerkna) a plotice obecná (Rutilus rutilus) byly v biomase plerocerkoidů zjištěny průměrné koncentrace Pb v rozmezí 3,20-4,51, Cd 0,21-0,31, Cr 1,13-3,16 mg/kg ve 100% sušiny. Podle hodnot podílu parazit akumuloval 12,5-18,9 krát více Pb, 2,3-3,0 krát více Cd a 4,4-14,1 krát více Cr, než ve svalovině hostitelů. Concentrations of heavy metals in two parasite-host systems (tapeworm vs. fish) were analysed. In the system Ligula intestinalis vs. common bream Abramis brama, white bream Blicca bjoerkna and roach Rutilus rutilus were found in the biomass of plerocercoids mean heavy metal concentrations ranging in Pb 3.20-4.51, in Cd 0.21-0.31, in Cr 1.13-3.16 mg/kg in the 100% dry matter. Regarding the values of accumulation ratio, the parasite accumulated 12.5-18.9 time more Pb, 2.3-3.0 times more Cd, and 4.4-14.1 times more Cr, compared to heavy metal concentrations in the muscles of intermediate hosts.
