Název v původním jazyce

The content of total mercury and methylmercury in common carp from selected Czech ponds.

Popis výsledku v původním jazyce

The aim of the present study was to investigate concentrations of total Merkury (THg) and methylmercury (MeHG) in the common carp from Czech ponds of Rožmberk, Spolský, Nezmar, and Velký Bědný. Seven common carps (Cyprinus caprio) from each of the pondswere caught. Muscle tissue, the liver, and the soft and hard roe were used for the tests. Total mercury and methylmercury were found in all the muscle tissue samples examined. Detection limits for total mercury and methylmercury determination methods were 0.001 mg kg?1 and 0.013 mg kg_1 respectively. Methylmercury levels in the liver and gonads were below the method?s limits of detection. THg and MeHg concentrations in muscle tissues were 0.018?0.063 mg kg?1 w.w. and 0.019?0.063 mg kg?1 w.w. respectively. MeHg made up 90?100% of THg in muscle tissues. Total mercury and methylmercury concentrations were significantly (P < 0.05) higher in fish from the Spolský pond than from the Nezmar pond. MeHg/THg ratios were significantly (P < 0.05) h
