Residual Metal Contamination of the ecosystem in the lower course of the Jihlava River

Popis výsledku v původním jazyce

In November 2001, October and November 2002, the concentrations of Hg, Cd, Pb, Cr, Cu, Zn and Ni were determined in four localities of the lower course of the Jihlava River (Czech Republic). The river water, sediments of the riverbed, zoobenthos and tissues of the fish (gill, gonad, skin, dorsal muscle) were analysed. The chub (Leuciscus cephalus) was used as the ichthyo-indicator. At the same time, the stability of the fish community was evaluated using electrofishing and applying basic ichthyologicalmethods. The work links up with previous investigation of the upper course of the Jihlava River (three localities) carried out by the authors in the same way in 1999. The aim of present study was the completion of previous investigation in the whole longitudinal river profile by monitoring selected heavy metals. The highest Cr (14.290 -- 77.070 mg/kg), Zn (13.600 -- 92.930 mg/kg) and Ni concentrations (12.290 -- 36.680 mg/kg)were found in sediments and their highest loading by all of the
