Copper, a native metal found in ores, is the principal metal in bronze and brass. It is a
reddish metal with a density of 8920 kg m− 3. All of copper's compounds tend to be brightly …

The biogeochemical cycling of metals in natural systems is often accompanied by stable
isotope fractionation which can now be measured due to recent analytical advances. In …

In plants, copper (Cu) acts as essential cofactor of numerous proteins. While the definitive
number of these so-called cuproproteins is unknown, they perform central functions in plant …

Metal oxide nanoparticles (NPs) are reported to impact plant growth in hydroponic systems.
This study describes the impact of commercial CuO (< 50 nm) and ZnO (< 100 nm) NPs on …

Metals in soil are potentially harmful to humans and ecosystems. Stable isotope
measurement may provide “fingerprint” information on the sources of metals. In light of the …

This paper reports the values of reduced partition function ratios (as 1000 ln β) for Fe, Ni, Cu,
and Zn bound to a number of inorganic and organic ligands. We used Density Functional …

The drainage of rice soils increases Cd solubility and results in high Cd concentrations in
rice grains. However, plant Cd uptake is limited by sorption to iron plaques, and Cd …

To study the sources and transformations of Hg in the rice plant (Oryza sativa L.), stable Hg
isotope variations in different tissues (foliage, root, stem, and seed) of rice which were …

Aims Recent advances in mass spectrometry have demonstrated that higher plants
discriminate stable Zn isotopes during uptake and translocation depending on …

Analyses of stable metal isotope ratios constitute a novel tool in order to improve our
understanding of biogeochemical processes in soil–plant systems. In this study, we used …
