Název v původním jazyce
Monitoring of risk metals in chub (Leuciscus cephalus L.) from the Svitava and Svratka rivers in the urban area of Brno, Czech Republic
Popis výsledku v původním jazyce
The aim of this study was to assess the impact of the Brno agglomeration on the distribution of risk elements (Pb, Cd, Cu, Zn, As) in tissues of a total of 50 chub (Leuciscus cephalus L.). 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 concentration was determined in the muscle, liver and kidney by high-resolution atomic absorption spectrometry. Electrothermic technique was used to assess lead, cadmium and copper concentrations; zinc content was determined by flame technique and arsenic by hydride generation. The highest concentrations of cadmium, lead, arsenic and zinc in individual tissues, ranked in a descending order as follows: kidney } liver }muscle; for copper it was liver } kidney } muscle. The highest concentrations of cadmium, arsenic and zinc were determined in chub kidney from the locality of Kníničky (1.35 +- 0.97, 0.186 +- 0.076, and 299.7 +- 123.4 mg?kg-1 respectively
