ABSTRACT

Nanoparticles are not confined to technology. They are abundantly distributed in nature; they are the building blocks of nature providing information on the earth systems process evolution and reflect its pattern. Nanomineral particles are observed to be   reactive; they also tend to bond with each other to create new pollution. These nanoparticles are more reactive for geometrical reasons -- the properties of surface atoms are increasingly sensitized as the size of the (nanomineral) particle decreases. This article seeks to demystify the state of nanoscience vis-à-vis mineral systems. The natural mineral nanoparticles or nanomineral particles/nanometal particulates, their formation, behaviour during transport, transformation and energy changes are discussed. The environmental concerns related to these natural nanoparticles are looked into with particular reference to contamination of elements of ecosystem.

Keywords: Nanomineral particles, reactive, surface atoms, mineral systems, behaviour, environment, ecosystem
