Copper Oxide Nanoparticles Toxicity on Eisenia fetida Earthworms and Bacterial Species

Abstract

The extensive use of nanoparticles (NPs) in a variety of applications has raised great concerns about their environmental fate and biological effects. To investigate the role of CuO NPs in soil on microbes and earthworms, we exposed microorganisms and earthworms ( Eisenia fetida ) to different concentrations of CuO NPs E. fetida to CuO NPs is not dose related. Dose related weight loss of earthworms was noticed after 15 days of exposure. This study will be very useful in regulation of nanomaterials that are entering into the environment.
