BackgroundIn a context of environmental monitoring around installations related to the nuclear fuel cycle, the Diffusive Gradient in Thin-films (DGT) technique captures the integrated concentration of U isotopes in their native environment, yielding comprehensive data on U origin (anthropogenic vs natural), total concentration, and mobility. Howeve...

Transformation represents one of the most important pathways for the horizontal transfer of antibiotic resistance genes (ARGs), which enables competent bacteria to acquire extracellular ARGs from the surrounding environment. Both heavy metals and irradiation have been demonstrated to influence the bacterial transformation process. However, the impa...

Tato práce byla zaměřena na studium speciace uranu pomocí teoretických výpočtů a s použitím metody luminiscenční TRLFS. V části Současný stav poznání byla problematika speciace zasazena do širšího kontextu popisem vzniku radioaktivních odpadů, nutnosti jejich bezpečného ukládání a konceptů, které by měly být pro ukládání využity. Speciace v tomto o...

To understand the fate of uranium (VI) in environments with technologically enhanced natural radioactivity, it is necessary to describe the links between its speciation and transfers in the soil-water-plant continuum. The links between speciation, lability and availability of U(VI) are major issues in forest environments where organic speciation of...

Minjingu phosphate ore is Tanzania's sole domestic supply of phosphorus (P). The ore contains medium to high concentrations of naturally occurring P2O5 (20–35 %) and relevant concentrations of uranium and rare earth elements (REEs) are also suspected to be present. Currently, neither uranium nor REEs are recovered. They either end up in mine tailin...

Uranium is a natural radioelement (also a model for heavier actinides), but may be released through anthropogenicactivities. In order to assess its environmental impact in a given ecosystem, such as the marine system, itis essential to understand its distribution and speciation, and also to quantify its bioaccumulation. Our objectivewas to improve ...

Due to their intrinsic properties, X-rays are at the basis of several methods of material investigation. In the case of crystals, X-ray scattering and diffraction allow structural and microstructural analysis. Whether the material under consideration is amorphous or crystallized, elemental analysis can be done through the measurement of the energie...

The tetravalent state is the main oxidation state of uranium in the nuclear fuel, and it is also the most prevalent reduced form under environmental conditions, particularly in the anoxic and reducing conditions of deep natural waters.[1-3] The speciation of uranium under these conditions is complex, and the potential formation of intrinsic colloid...

In this study, I assessed the groundwater quality of drinking water from domestic wells within the Upper Big Blue Natural Resources District (UBB NRD), in southeastern Nebraska. Rural residents in the UBB NRD obtain drinking water from domestic wells that terminate in the High Plains Aquifer, one of the most important groundwater resources in the U...

Uranium-stressed soil caused by nuclear industry development and energy acquisition have attracted extensive attentions for a long time. This study investigated the effects of biochar application with different pyrolysis temperatures (300 ℃, 500 ℃ and 700 ℃) on remediation of uranium-stressed soil. The results showed that higher pyrolysis temperatu...
