| Description
| - Cílem práce bylo stanovit koncentrace celkové rtuti a methylrtuti ve svalovině 55 kusů jelce tlouště (Leuciscus cephalus) ze sedmi hlavních přítoků (Orlice, Chrudimka, Cidlina, Jizera, Vltava, Ohře, Bílina) řeky Labe a vyhodnotit zdravotní rizika konzumace ryb ze sledovaných přítoků. Celková rtuť byla stanovena atomovou absorpční spektrometrií na přístroji AMA-254 a methylrtuť ve formě CH3HgCl plynovou chromatografií. Nejvyšší průměrné koncentrace celkové rtuti a methylrtuti byly nalezeny v Jizeře (0,27?0,19 mg/kg a 0,23?0,15 mg/kg) a nejnižší koncentrace byly nalezeny u tloušťů z Cidliny (0,07?0,05 mg/kg a 0,06?0,04 mg/kg). Průměrná hodnota poměru methylrtuti k celkové rtuti byla 83 ? 15%. Ukazatele rizika konzumace ryb vypočítané pro jednotlivé sledované přítoky se pohybovaly mezi 0,01 a 0,04. Výsledky této práce ukázaly, že hlavní přítoky významně nepřispívají ke kontaminaci řeky Labe rtutí. (cs)
- The aim oh the present study was to investigate the concentrations of total mercury and methylmercury in muscle of 55 chub (Leuciscus cephalus) from seven main tributaries (Orlice, Chrudimka, Cidlina, Jizera, Vltava, Ohře, Bílina) of the Elbe River and to evaluate the health risks of eating fish from the tributaries monitored. Mercury was determined by means of cold vapour atomic absorption using AMA-254, methylmercury in the form of CH3HgCl by gas chromatography. The highest mean concentrations of total mercury and methylmercury were found in the Jizera (0,27?0,19 mg/kg and 0,23?0,15 mg/kg, respectively) and the lowest mean concentrations of total mercury and methylmercury were found in the chub from the Cidlina (0,07?0,05 mg/kg and 0,06?0,04 mg/kg, respectively). The average methylmercury ?to- total mercury ratio was 83?15%. The fish intake hazard indexes calculated for the individual tributaries monitored were between 0,01 and 0,04. The results of this study show that the Elbe River is not signific
