'Nanominerals' influence Earth systems from ocean to atmosphere to biosphere
Date:3/20/2008

The ubiquity of tiny particles of minerals--mineral nanoparticles--in oceans and rivers, atmosphere and soils, and in living cells are providing scientists with new ways of understanding Earth's workings. Our planet's physical, chemical, and biological processes are influenced or driven by the properties of these minerals.

So states a team of researchers from seven universities in a paper published in this week's issue of the journal Science: "Nanominerals, Mineral Nanoparticles, and Earth Systems."

The way in which these infinitesimally small minerals influence Earth's systems is more complex than previously thought, the scientists say. Their work is funded by the National Science Foundation (NSF).

"This is an excellent summary of the relevance of natural nanoparticles in the Earth system," said Enriqueta Barrera, program director in NSF's Division of Earth Sciences. "It shows that there is much to be learned about the role of nanominerals, and points to the need for future research."

Minerals have an enormous range of physical and chemical properties due to a wide range of composition and structure, including particle size. Each mineral has a set of specific physical and chemical properties. Nanominerals, however, have one critical difference: a range of physical and chemical properties, depending on their size and shape.

"This difference changes our view of the diversity and complexity of minerals, and how they influence Earth systems," said Michael Hochella of the Virginia Polytechnic Institute and State University in Blacksburg, Va.

The role of nanominerals is far-reaching, said Hochella. Nanominerals are widely distributed throughout the atmosphere, oceans, surface and underground waters, and soils, and in most living organisms, even within proteins.

Nanoparticles play an important role in the lives of ocean-dwelling phytoplankton, for example, which remove carbon dioxide from the atmosphere.
