Impact of Nanomaterials on Earthwoms : A New Threat to Megadrili Resources

Abstract

Nanoscience is a very exciting and useful branch of science, in which, nanoparticles are designed for various purposes. World market for nanomaterials is increasing rapidly and advanced countries are earning a substantial amount from marketing of nanoparticles. But other side of the coin is related to the ill-effects of nanomaterials. Now-a-days nanomaterials are widely and indiscriminately used without realizing their short- and long-term consequences. Applications of nanomaterials may lead to several adverse effects on fauna and flora of the Earth. The disposed nanomaterials contaminate soil system which is the home of various invertebrates including earthworms. They effect metabolism, reproductive potential and life cycle and sometimes lead to death of organisms living beneath our feet. It declines soil sustainability and hampers productivity leading to economic losses. Therefore, no nanomaterial should be used without its impact assessment otherwise we will not be in a position to revert irreparable losses caused by use of nanomaterials
