The aim of this study was to determine the concentrations of mercury in tissues of the European chub (Squalius cephalus) which is used as a bioindicator of pollution of aquatic ecosystems. Levels of methylmercury and total mercury were determined in muscle and skin of twenty fishes caught at two sampling sites in the Svratka River, near the Brno City, Czech Republic. The effect of municipal wastewater treatment plant (WWTP), which is located between these two sampling sites, was considered. Determination of methylmercury was carried out by optimized extraction method and gas chromatography with electron capture detector. Total mercury concentrations were determined using the technique of direct combustion. The same methodology was applied to certified reference material. Concentrations of methylmercury ranged from 124.25 to 255.32 mu g.kg(-1) in the muscle and from 34.18 to 103.98 mu g.kg(-1) in skin samples of fishes caught upstream to the WWTP. Downstream to the WWTP, concentrations of methylmercury ranged from 59.74 to 183.50 mu g.kg(-1) in the muscle and from 13.62 to 76.88 mu g.kg(-1) in the skin. Concentrations of total mercury in muscle and skin of fishes caught upstream and downstream to the WWTP showed a similar pattern. Differences between levels of mercury in different fish tissues were compared, and the impact of WWTP was assessed.
