Uranium bearing dissolved organic matter in the porewaters of uranium contaminated lake sediments
Breda Novotnik, W. Chend, R. Douglas Evans
Izvirni znanstveni članek
Oznake: uranium;lake sediments;porewater;disolved organic matter;high resolution mass spectrometry;
Uranium (U) mobility in the environment strongly depends on its oxidation state and the presence of complexing agents such as inorganic carbon, phosphates, and dissolved organic matter (DOM). Despite the importance of DOM in U mobility, the exact mechanism is still poorly understood. Therefore, th ...

Uranium isotope fractionation during adsorption, (co)precipitation, and biotic reduction
Duc Huy Dang, Breda Novotnik, Wei Wang, R. Bastian Georg, R. Douglas Evans
Izvirni znanstveni članek
Oznake: Uranium;fractionation;biotic;abiotic;oxides;
Uranium contamination of surface environments is a problem associated with both U-ore extraction/processing and situations in which groundwater comes into contact with geological formations high in uranium. Apart from the environmental concerns about U contamination, its accumulation and isotope com ...

Variations in U concentrations and isotope signatures in two Canadian lakes impacted by U mining
Wei Wang, Duc Huy Dang, Breda Novotnik, Thai T. Phan, R. Douglas Evans
Izvirni znanstveni članek
Oznake: uranium;isotope composition;uranium tailings;biogeochemical cycling;redox chemistry;
Temporal and vertical variations in uranium (U) concentrations and U isotope (δ238U, ‰) signatures were examined in sediment cores collected seven times over a one year period, from two lakes in Ontario, Canada, which are contaminated with U by historical mining activities. Bow Lake is holomictic, ...
