The concentrations of U in natural waters are usually low, being typically less than 4 μg/L in
river water, around 3.3 μg/L in open seawater, and usually less than 5 μg/L in groundwater …

The photocatalytic conversion of soluble U (VI) into insoluble U (IV) is a robust strategy to
harvest aqueous uranium, but remains challenging owing to the intermittent availability of …

As the parent element in the U-Pb and Pb-Pb radiochronometers, uranium (U) was one of
the first heavy elements whose isotopic composition was carefully determined. Thought to …

Uranium is a toxic and pervasive geogenic contaminant often associated with organic
matter. Its abundance and speciation in organic-rich permafrost soils are unknown, thereby …

Tracing pollution originating from uranium (U) mining activities is a key challenge due to the
diversity of U sources (geochemical background versus U-ore) and its daughter …

The transformation of the mineral ferrihydrite in reducing environments, and its impact on the
mobility of incorporated trace metals, has been investigated in model laboratory studies, but …

The objective of this study was to determine if U sediment concentrations in a U-
contaminated wetland located within the Savannah River Site, South Carolina, were greater …

In this research, we focus our attention on the leaching peculiarity of uranium-containing Mg–
Al layered double hydroxide (LDH) which is one kind of waste sediment in uranium tailings …

Tims Branch riparian wetland located in South Carolina, USA has immobilized 94% of the U
released> 50 years ago from a nuclear fuel fabrication facility. Sediment organic matter (OM) …

High U concentrations (reaching up to 14850 mg⋅ kg− 1), were determined in soils and
sediments of a wetland downstream of a former U mine in France. This study aims to identify …
