| Description
| - Cílem této práce bylo zjistit a zhodnotit stav zatížení tkání ryb z údolní nádrže Skalka v České republice celkovou rtutí a methylrtutí. Tato nádrž byla několik desítek let znečišťována odpadními vodami obsahujícími rtuť. V srpnu 2003 bylo odloveno celkem 30 kusů ryb, z toho: 5 kusů plotice obecné (Rutilus rutilus), 8 kusů cejna velkého (Abramis brama), 2 kusy cejnka malého (Blicca bjoerkna), 7 kusů tolstolobika pestrého (Aristichthys nobilis), 4 kusy bolena dravého (Aspius aspius), 3 kusy úhoře říčního (Anguilla anguilla) a 1 kus sumce velkého (Silurus glanis). K analýzám byla použita svalovina, játra a gonády. Průměrný obsah celkové rtuti byl ve svalovině bolena dravého (jako zástupce dravých druhů) 3,11 +/- 0,20 mg kg-1 a u cejna velkého (jako zástupce nedravých druhů) 0,96 +/- 0,22 mg kg-1. Všechna celková rtuť byla ve svalovině bolena dravého a cejna velkého ve formě methylrtuti. Obsah celkové rtuti a methylrtuti byl signifikantně (p < 0,05) vyšší ve svalovině a játrech ve srovnání s gonádami. (cs)
- The aim of this case study was to investigate the total mercury and methylmercury contamination of fish from the Skalka reservoir, Czech Republic. The reservoir had been polluted with mercury-containing sewage water for several decades. In total, 30 fish was sampled in August 2003. The fish caught included 5 roach (Rutilus rutilus), 8 bream (Abramis brama), 2 silver bream (Blicca bjoerkna), 7 big head carp (Aristichthys nobilis), 4 asp (Aspius aspius), 3 eel (Anguilla anguilla) and 1 wels catfish (Silurus glanis). Muscle tissue, the liver and the gonads were used for mercury determination. Total mercury in muscle tissue of the asp (as the representative of predatory species) and the bream (as the representative of non-predatory species) averaged 3.11 +/- 0.20 mg kg-1 and 0.96 +/- 0.22 mg kg-1, respectively. All total mercury in muscle tissue of the asp and the bream was in methylmercury form. The content of total mercury and methylmercury was significantly (p < 0.05) higher in muscle tissue and the
