Heavy Metals Toxicity and the Environment

Heavy metals are naturally occurring elements that have a high atomic weight and a density at least 5 times greater than that of water. Their multiple industrial, domestic, agricultural, medical and technological applications have led to their wide distribution in the

Agronomy

The aim of the work described here was to understand the pedogeochemical signature of five rare earth elements (REEs; Ce, Nd, La, Y, and Sc) in vineyard soils in Campo de Calatrava (a unique territory with calcareous, volcanic and metamorphic rocks). The mean contents in surface horizons of Ce, Nd, La, Y, and Sc were 65.7, 32.0, 35.5, 18.8, and 13.9 mgkg–1, respectively.

Global Marine Mineral Resources

The Global Marine Mineral Resources project researches deep ocean minerals within the U.S. Exclusive Economic Zone and throughout the Earth's oceans. Our research concerns the setting, genesis, and metal enrichment processes of mineral deposits, the relationship between marine minerals related and deep-sea biota, and the potential geochemical

Greenland: what is China doing there and why?

In 2013, Greenland repealed a law banning the mining of radioactive material and rare earth elements in order to diversify its economy. [72] To combine this with the erosion of the Greenland ice sheet, which makes more areas of Greenland open for mining projects, ensures increased (economic) opportunities.
