ABSTRACT

 

The extensive use of nanoparticles (NPs) in a variety of applications has increased great concern about their environmental fate and biological effects. The present study aimed to evaluate the effect of Ag-NPs coated paper on growth and nutrient content and its bioaccumulation in worm species, Eudrilus eugeniae. At the end 60 days of experiment, the results revealed that in case of growth and reproduction concern, the silver coated paper dishes do not much affecting the growth and mortality of worm but comparatively over the card paper, they decreases the rate of reproduction. In bioaccumulation experiment, it was found that the earthworms are very well adapted for accumulations because silver particles are gradually accumulate without recording any significant change in tissue metal concentration. Except Zn, Cu, Mg and lime, appreciable amount of nutrients like N, P, K, Na and Mn etc were significantly increased in worm cast.
