Mercury is one of the few metals which strongly bioconcentrates and biomagnifies, and has only harmful effects with no useful physiological functions when is present in fish and wildlife, and is easily transformed from a less toxic inorganic form to a more toxic organic form in fish tissue. One organic form of mercury, methyl mercury, is of particular concern because it can build up in certain fish. For this study were chosen 5 aquatic complexes (Somova-Parches, Sontea-Fortuna, Matita-Merhei, Rosu-Puiu and Gorgova-Uzlina), of the Danube delta, one of the most important biodiversity Reserve in Europe. The samples were analysed by cold vapour atomic absorption spectrometry (CVAAS) procedure, a physical method based on the absorption of radiation at 253.7 nm by mercury vapour. The aim of this study was to evaluate mercury levels in freshwater fish species (approximately 500 samples from different species) from the Danube delta Biosphere Reserve.
