The results of the gamma-spectrometric measurements in a 16500 ha large region south-western Serbia, are presented. Activity concentrations 40K, 137Cs, and 210Pb different deciduous evergreen trees investigated. For all investigated isotopes, there is tendency that, on average, lowest activity were found tree stems, then leaves, while highest ones soil. Statistical analysis did not show any dif...

Mercury (Hg) contamination is pervasive in aquatic ecosystems and its bioaccumulation may lead to severe health concerns for both wildlife and humans. In this study we quantify historical Hg fluxes to the profundal sediment of Seneca Lake, NY. Previous studies show that the highest surface sediment Hg concentrations occur here, near a major tributary, the Keuka Lake Outlet. This tributary hoste...
