Description
  • The aim of the present study was to assess the contamination of the upper reaches of the Tichá Orlice River by metals and thus to help evaluate the reasons for unsatisfactory results in the reproduction of salmonoid fish. Metal concentrations in brown trout (Salmo trutta) were used for the contamination assessment. The samples were collected in June 2000 and 2001 at two collection sites from the Tichá Orlice River (Červená Voda - 103rd river km; Lichkov - 93rd river km) and its tributary Kralický brook (100th river km.). At each of the sites, 14 brown trout were collected in each of the periods of monitoring. The AAS method was used to determine the total mercury, arsenic, cadmium, lead, copper, zinc, chromium and nickel contents in the muscle tissue of the fish and in aquatic sediments. The Kralický brook is an important anthropogenic source of metal contamination (particularly of mercury and copper) for the Tichá Orlice River. In the muscle tissue of the brown trout collected at Červená Voda, signif

  • Cílem práce bylo posoudit kontaminaci horního toku řeky Tiché Orlice kovy a přispět tak k hodnocení příčin neuspokojivých výsledků reprodukce lososovitých ryb. K indikaci kontaminace byl použit pstruh obecný (Salmo trutta). Odběry vzorků byly provedeny v měsíci červnu 2000 a 2001 na dvou lokalitách řeky Tiché Orlice (Červená Voda - 103 ř. km; Lichkov - 93 ř. km) a na jejím přítoku Kralickém potoce (100 ř. km.). Na každé lokalitě bylo v obou sledovaných obdobích odloveno po 14 kusech pstruha obecného. Ve svalovině ryb a v sedimentech dna byl metodou AAS stanoven obsah celkové rtuti, arsenu, kadmia, olova, mědi, zinku, chromu a niklu. Výraznou antropogenní kontaminaci kovy (zejména rtutí a mědí) přináší do Tiché Orlice Kralický potok. Signifikantně vyšší obsah arsenu byl zjištěn ve svalovině pstruhů obecných v lokalitě Červená Voda ve srovnání s níže položenými lokalitami. Tento rozdíl byl diskutován v souvislosti s odlišnými fyzikálně - chemickými vlastnostmi vody a s potravní nabídkou. (cs)
