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 …

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 …

The oceanic biogeochemical cycles of the transition metals have been eliciting considerable
attention for some time. Many of them have isotope systems that are fractionated by key …

The number of studies using various stable isotope systems for tracing contamination
sources and various biogeochemical processes is rapidly rising due to the increased …

The fractionation of stable copper (C u) isotopes during uptake into plant roots and
translocation to shoots can provide information on C u acquisition mechanisms. Isotope …

Iron and copper isotopes are useful tools to track redox transformation and biogeochemical
cycling in natural environment. To study the relationships of stable Fe and Cu isotopic …

Recent reports suggest that significant fractionation of stable metal isotopes occurs during
biogeochemical cycling and that the uptake into higher plants is an important process. To …

The use of multiple isotopic ratios and statistical methods can substantially increase the
reliability and precision of determining contamination sources and pathways. In this study …
