"The aim of the present study was to assess the contamination of the upper reaches of the Tich\u00E1 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 Tich\u00E1 Orlice River (\u010Cerven\u00E1 Voda - 103rd river km; Lichkov - 93rd river km) and its tributary Kralick\u00FD 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 Kralick\u00FD brook is an important anthropogenic source of metal contamination (particularly of mercury and copper) for the Tich\u00E1 Orlice River.
