Název v původním jazyce

Spatiotemporal trends of heavy metal concentrations in fish of the River Morava (Danube basin)

Popis výsledku v původním jazyce

The aim of this study was to assess Hg, Cd and Pb contamination in muscle tissue of fishes over the longitudinal profile of the River Morava and to detect any temporal trends over the past 18 years. Concs of heavy metals ranged as follows: Hg 0.015-0.369mg/kg; Cd 0.001-0.254 mg/kg and Pb 0.006-1.505 mg/kg. Hg levels did not exceed the max. allowed conc. in the CR (0.5 mg/kg). Content of Cd and Pb in fish muscle exceeded the max. allowed levels (0.05 and 0.3 mg/kg) in 11 and 4 samples, respectively. Onaverage, the order of metal conc. in fish muscle was: Hg>Pb>Cd. No significant differences were found between sites. Significant differences were found, however, for the interannual comparison of Cd and Pb (but not Hg) at different sites (p 0.05). A catastrophic flood in 1997 resulted in an increase in metal concs, especially Cd and Pb, in the following 1998 season. Our results indicate that the Morava river basin does not represent a threatening source of Hg, Cd or Pb for the River Danu
