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 …

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 …

Copper (Cu) is not only an essential metallic element for human and organisms, but also a
toxic and pernicious element when its environmental content exceeds a certain threshold …

Background Particles from non-exhaust emissions derived from traffic activities are a
dominant cause of toxic metal pollution in urban environments. Recently, studies applying …

The distinct isotopic composition of metallic elements observed in different sources and
reservoirs provides an important perspective on tracing the source, transportation, and …

Farmland top soils and soil profiles situated in the karst area of Guilin, Guangxi Zhuang
Autonomous Region, southern China, reveal different degrees of heavy metal pollution, both …

The supplementation of Zn to farm animal feed and the excretion via manure leads to an
unintended Zn input to agricultural systems, which might compromise the long-term soil …

Zinc is a ubiquitous metal, acting both as an essential and a toxic element to organisms
depending on its concentration and speciation in solution. Human activities mobilize and …

In the mining area affected by coal mining activities for a long time, heavy metal Zn pollution
poses a serious threat to soil quality and human health, and direct evidence showing the …

The stable isotope compositions of Cu and Zn in major geochemical reservoirs are
increasingly studied with the aim to develop these isotope systems as tools to investigate the …
