The aim of this study was to assess the impact of the Brno agglomeration (Czech Republic) on the distribution of risk elements (Pb, Cd, Cu, Zn, As) in tissues of 50 chubs (Leuciscus cephalus). Contamination by metals was monitored in fish from different sites on the Svitava and Svratka rivers in the urban agglomeration of Brno in 2008. Metal concentrations were determined in muscles, livers and kidneys by high-resolution atomic absorption spectrometry. Electrothermic technique was used to assess Pb, Cd and Cu concentrations; Zn conc. was determined by flame technique and As conc. by hydride generation. The highest concentrations of Cd, Pb, As and Zn in individual tissues ranked in a descending order as follows: kidney more than liver more than muscles; for Cu it was liver more than kidney more than muscles. The highest concentrations of Cd, As and Zn were determined in chub kidneys from the locality of Kninicky (1.35+/-0.97, 0.186+/-0.076, and 299.7+/-123.4 mg/kg, respectively); the highest concentration of Pb was on the Svratka before junction (0.28+/-0.19 mg/kg). The highest contamination with risk metals was found in chub from the Svratka river. The concentrations of all risk elements do not pose any environmental or health threat.
