Název v původním jazyce

Methylmercury in tissues of fish from the Svratka River, Czech Republic

Popis výsledku v původním jazyce

Mercury is a global pollutant with a disturbing occurrence and fate in aquatic ecosystem where it is accumulated especially in fish through a transformation process to create its most toxic form - methylmercury. This study is focused on the evaluation ofcontamination of fish (muscle and skin tissue) from the Svratka River (South Moravian Region, Czech Republic) by methylmercury. The fish were caught at two sampling sites - upstream and downstream from the municipal wastewater treatment plant (WWTP) Brno-Modřice. Extraction of methylmercury was performed according to a method based on methylmercury digestion in hydrochloric acid and its subsequent extraction with toluene. The subsequent analysis was carried out using a gas chromatograph equipped with aDB-17 capillary column and a micro electron capture detector. Selected samples were also analyzed to determine total mercury concentrations using a special single-purpose atomic absorption spectrometer for determination of mercury. Obtai
