Abstract
Zinc deficiency is one of the major malnutritional problems worldwide specifically in developing and developed countries. The zinc uptake takes place in human body in ionic form and metabolized naturally and converted into nano form. In the present study zinc oxide nanoparticles (ZnONPs) were synthesized by starch. The synthesized different ZnONPs were characterized by Fourier Transform Infra-Red spectroscopy (FTIR) and Scanning Electron Microscopy (SEM) coupled with Energy Dispersive X ray analysis (EDX). FTIR analysis revealed Zinc peak at 405.05 cmˉ1.The average size of the synthesized ZnONPs was in the range from 200-300 nm with flower like shape. Furthermore, toxicity and level of nanoparticle accumulation were evaluated in young and adult guppies (Poecilia reticulata) using different concentration of ZnONPs. To explore the toxicological effect, the different concentration of nanoparticles administered in young and adult guppies. There was a dose dependent toxicological effects were noted in the guppies.
